Description

Remote control device, display system and display method

technical field

The present invention relates to a remote control device, a display system and a display method, and in particular to a remote control device, a display system and a method for adjusting a display screen according to the pointer movement amount and pointer movement direction.

Background technique

In recent years, with the gradual popularization of electronic whiteboards and interactive projectors, the technology of optical pens for displaying mouse pointers has also been improved. According to the trajectory sensing method, the trajectory sensing method of the optical pen can be divided into two types: the image signal includes and does not include coordinate information.

Among them, the image signal does not include the type of coordinate information means that the optical pen itself simply generates pointing points on the display screen in response to the user's operation, and then the coordinate position of the pointing points is detected by a positioning device installed near the display screen; The type of coordinate information included in the image signal means that the optical pen can read the coordinate information carried in the image signal, and judge the current coordinate position of the pointing point on the display screen accordingly.

FIG. 1A is a schematic diagram of a conventional "image signal does not contain coordinate information" technology display system, please also refer to US Patent No. 5,528,263, "Interactive projected video image display system" (Interactive projected video image display system). In this figure, the display system 13 must Related sensing devices 111 are set around the projection screen 11, and the optical pen 10 will control the projector 112 to generate pointing points on the projection screen 11 according to the user's operation. Then, at least one sensing device 111 will point to the The location is communicated back to the host computer 12 .

Under this framework, when the image signal does not contain coordinate information to sense the trajectory of the optical pen, the sensing coordinates of the sensing device 111 must be consistent with the display coordinates of the projection screen of the projector 112; otherwise, even if the sensing device 111 can correctly The sensing coordinates of the pointing point are (X.Y), but the display coordinates (X.Y) in the projection screen of the projector 14 are not at the same position, so the pointing point of the mouse will be displayed at different positions on the projection screen 11, resulting in the use of Some people think that the optical pen 10 is faulty.

In other words, when the optical pen trajectory is sensed in a way that the image signal does not contain coordinate information, whenever the relative positional relationship between the sensing device 111, the projection screen 11 and the projector 14 changes, (for example: the sensing device 111 and the projector 14 is moved from classroom A to meeting room B for resetting), the sensing device 111 must first be recalibrated with the projector 112, which also causes limitations and inconvenience in use.

FIG. 1B is a schematic diagram of a conventional image signal including coordinate information technology display system. Please also refer to US Patent No. 7,421,111, "Light pen system for pixel-based displays". First, the host computer 16 controls the projection device 14 Interlaced projection of user video signal screens and a series of coordinate patterns (sequence of patterns) in sequence on the predetermined display area, for example: 59 frames (frames) of user video signal screens are projected per second, and 1 frame coordinates are inserted and projected Pattern; a series of coordinate patterns are interspersed in the video signal screen played by the user at a very low ratio, so the user cannot feel the difference in the video screen with the naked eye.

In this way, by inserting a series of coordinate patterns in the 60th picture frame time sequence, each position on the display screen has a specific sequence of light intensity (aunique sequence of light intensity). Therefore, according to the order of the light intensity sequence at the specific position where the tip of the optical pen is aligned by the optical pen sequence at the 60th frame, it can be judged that in the display area, the position of the point where the tip of the optical pen is currently aligned corresponds to What is the encoding of . Furthermore, where in the display area is the position of the indication point of the optical pen 15 can be determined according to the light intensity sequence.

For example: when the coordinate pattern is at the first time point t1 (the 60th frame timing), the block in the upper left corner of the display screen is shaded; when the coordinate pattern is at the second time point t2 (the 120th frame timing), the display screen The upper right block is shaded; when the coordinate pattern is at the third time point t3 (the 180th frame timing), the lower right block of the display screen is shaded; the coordinate pattern is at the fourth time point t4 (the 240th frame timing) ), the block in the lower left corner of the display screen is shaded.

So: when the code sequence sensed by the optical pen 15 is (1, 0, 0, 0) at the first time point t1, the second time point t2, the third time point t3, and the fourth time point t4 respectively, It can be judged that the nib of the optical pen 15 is currently aligned with the upper left corner of the display screen, that is, the current pointing point is located in the upper left corner of the block. Similarly, when the code sequence is (0, 1, 0, 0), it is judged that the nib of the optical pen 15 is currently aligned with the upper right block of the display screen, that is, the current pointer position is located in the upper right block.

Since the coordinate pattern picture and the user image signal picture are projected and output through the same projection device 14, even if the display system 17 shown in FIG. 1B is moved, it can be used directly without correction when resetting.

However, the display screens described below are applicable to display systems that do not contain or contain coordinate information in image signals. For ease of description, it will not be distinguished below whether the image signal contains coordinate information.

Please refer to FIG. 2A , which shows a cross-shaped cursor symbol representing a point 23 at the intersection of the optical pen pointing path and the display screen 22 in the display screen. When the user moves the optical pen 21 , the position of the cursor symbol 23 on the display screen 22 will change correspondingly.

Referring to FIG. 2B , the display system can also provide a writing function. When the user activates the writing function, the moving path of the optical pen 21 will become the input handwriting 26 input by the user.

In FIG. 2B , the conventional technology simply provides the function of displaying handwriting input by the optical pen. However, the input handwriting written by the optical pen does not change. If the user wishes to change the color or width of the input handwriting, he needs to re-select the palette setting in the display screen 22 to update the color of the trace. If the user needs to draw or write in multiple colors, the user must repeatedly enable the function of the screen color palette, and then re-select the color setting used by the newly selected input track. This kind of process is too complicated for the user and unfavorable to use.

Furthermore, if the user needs to adjust the display screen 22 in the window, it is usually necessary to adjust the vertical scroll bar 24 and the horizontal scroll bar 25 in the display screen 22 . However, for the horizontal or vertical adjustment of the display screen 22 , the user often needs to additionally use a mouse, a touch pad, and the like to control it on the computer host side. Therefore, the user must alternately use the optical pen and the touch panel to smoothly draw or write.

detailed description

According to an embodiment of the present invention, the present invention uses the remote control device to directly adjust the display screen, such as adjusting the vertical scroll bar of the display screen, adjusting the horizontal scroll bar of the display screen, and adjusting the zoom ratio of the display screen. Moreover, the optical pen of the present invention can directly control the width, brightness, color and other functions of the input handwriting when drawing patterns. For ease of description, an optical pen is used as an example of the remote control device below, but the type of the remote control device does not need to be limited.

Please refer to FIG. 3A , which is a schematic diagram of the optical pen of the present invention. A scroll wheel 352 is provided near the tip of the optical pen 35 housing, so that the user can use fingers to operate the scroll wheel 352 while holding the optical pen 35 . Furthermore, the user only needs to change the posture of the optical pen 35 and rotate the scroll wheel 352 by manipulating the hand, and various types of adjustments can be made to the display screen according to these operations. The details are as follows.

Please refer to FIG. 3B , which is a schematic diagram of the internal block of the optical pen of the present invention. The optical pen 35 includes a pen-shaped housing 351 , a scroll wheel 352 , a gravity sensing unit 353 , and a transmission unit 354 . Both the gravity sensing unit 353 and the transmission unit 354 are disposed inside the housing 351 , and the roller 352 is disposed on the surface of the pen-shaped housing 351 . In addition, the transmission unit 354 is electrically connected to the gravity sensing unit 353 and the input unit 352 .

Wherein, the scroll wheel 352 can be regarded as an input unit, and pointer movement information (A) can be generated according to the rotation amount and rotation direction of the scroll wheel 352; the gravity sensing unit 353 can generate placement information (A) according to the placement posture of the pen-like housing 351 B). Afterwards, the transmission unit 354 outputs the pointer movement information (A) and placement information (B) through bluetooth, wireless network and other means.

Please refer to FIG. 3C , which is a schematic diagram representing the placement posture of the optical pen by using the long-axis horizontal angle. In the present invention, the pen body direction from the tail end of the optical pen 35 to the pen tip is defined as the long axis of the casing, and the extension direction of the long axis of the casing is further defined as the indication path. When the user holds the optical pen 35 and controls its posture, it means that the direction of the body of the optical pen changes, and the horizontal included angle of the long axis changes accordingly.

Therefore, the gravity sensing unit 353 can use the long-axis horizontal angle to represent the placement information (B); and, according to the user's control, the scroll wheel 352 is rotated to generate the index movement direction (a1) and the index movement amount (a2 ) pointer movement information (A).

Please refer to FIG. 4 , which is a schematic diagram of the display device of the present invention. According to the idea of the present invention, the display device may be an electronic whiteboard whose image signal does not include coordinate information, or a projection device whose image signal includes coordinate information. Of course, the display device may also be a projection screen, a liquid crystal screen, a screen of a tablet computer or a notebook computer, etc., which have the function of sensing and indicating.

The display device 32 includes: a receiving unit 321 , a display control unit 323 , and a display unit 322 . Wherein, the receiving unit 321 is signally connected to the transmitting unit of the remote control device, and the display control unit 323 is electrically connected to the receiving unit 321 and the display unit 322 .

After the receiving unit 321 receives the pointer movement information (A) and placement information (B), the display control unit 323 adjusts the display screen presented by the display unit 322 according to the pointer movement information (A) and placement information (B).

In addition, the display device 32 may also include a storage unit (not shown), which is electrically connected to the display unit 322 . When the display device 32 is used with drawing software, the display device 32 can use the storage unit to store the position change of the input handwriting, as well as the setting values of the display attributes such as the size setting, width setting, color setting, and brightness setting of the input handwriting .

Please refer to FIG. 5 , which is a first embodiment of a flow chart of adjusting a display screen by using an optical pen according to the present invention. First, the display device receives the pointer movement information (A) and placement information (B) output by the optical pen (step S52); then, it determines whether the horizontal angle of the major axis is smaller than the first horizontal angle threshold (step S53), that is Judgment is made according to the horizontal angle of the major axis represented in the placement information (B).

If the determination is not true, the display device controls the vertical movement of the display screen according to the pointer movement information (A) (step S55 ), for example, vertical scrolling up or down (vertical scrollup/down). On the contrary, if the determination is true, the display device controls the horizontal movement of the display screen according to the pointer movement information (A) (step S54 ), for example: leftward or horizontal scrolling (horizontal scroll right/left).

Take FIG. 6A to FIG. 6C as an example. Assume that FIG. 6A is the original display screen. When the horizontal angle of the major axis is large and greater than the first horizontal angle threshold, it means that the placement posture of the optical pen is closer to the vertical direction. At this time, the display device controls the display screen to move vertically according to the pointer movement information (A).

If the user turns the scroll wheel toward the end of the pen, and the pointer movement direction ( a1 ) is defined as the positive movement direction (+), then as shown in FIG. 6B , the display screen will be moved vertically upwards.

And, the range by which the display screen will be moved upward is determined according to the index movement amount (a2). For example: when the scroll wheel rotates half a circle towards the tail of the pen, the content of the display screen will move up 100 pixels; and, when the scroll wheel rotates one circle towards the tail of the pen, the content of the display screen will move up 200 pixels.

Similarly, if the user turns the scroll wheel toward the pen tip, and the pointer movement direction ( a1 ) is defined as a negative movement direction (-), then as shown in FIG. 6C , the display screen will be moved downward. And, the magnitude of the vertical downward movement of the display screen is determined according to the index movement amount (a2).

Take FIG. 7A to FIG. 7C as an example. Assume that FIG. 7A is the original display screen. When the long-axis horizontal angle is very small and smaller than the first horizontal angle threshold, it means that the placement posture of the optical pen is closer to the horizontal direction. At this time, the display device controls the display screen to move horizontally according to the pointer movement information (A).

If the user turns the scroll wheel towards the tail of the pen, and the pointer movement direction ( a1 ) is defined as the positive movement direction (+), then as shown in FIG. 7B , the display screen will be moved to the left along the horizontal direction. And, the width of the horizontal movement of the display screen to the left is determined according to the index movement amount (a2).

Similarly, if the user turns the scroll wheel towards the direction of the optical pen tip, and the pointer movement direction ( a1 ) is defined as a negative movement direction (-), then as shown in FIG. 7C , the display screen will be moved to the right. And, the magnitude of the horizontal movement of the display screen to the right is determined according to the index movement amount (a2).

As can be seen from the above description, the optical pen of the present invention can directly move the display screen vertically and horizontally.

In addition, referring to FIG. 8A and FIG. 8B , when the pointing path of the optical pen points to the display screen 82 , a cross-shaped cursor symbol can be displayed on the display screen. If the pointing path of the optical pen 81 does not point to the display screen, the cursor symbol will not be displayed. Therefore, the present invention can further allow the user to use the optical pen to zoom the display image according to whether the indication path intersects with the display image.

Please refer to FIG. 9 , which is a second embodiment of the flow chart of adjusting the display screen by using the optical pen according to the present invention. First, receive the pointer movement information (A) and placement information (B) output by the optical pen (step S62); then judge whether the long-axis horizontal angle is smaller than the first horizontal angle threshold (step S63), that is, according to the placement The horizontal angle of the major axis represented in the information (B) is used for judgment.

If the judgment is not established, the vertical movement of the display screen is controlled according to the pointer movement information (A) (step S67). The control method of step S67 is the same as that of step S55 in FIG. 5 , please refer to the descriptions in FIG. 6A , FIG. 6B , and FIG. 6C , and details will not be repeated here.

If the judgment is true, it is further judged whether the instruction path points to the display screen (step S64).

If the indication path does not point to the display screen, the display device will control the horizontal movement of the display screen according to the pointer movement information (A) (step S65). The control method of step S65 is the same as that of step S54 in FIG. 5 , please refer to the descriptions in FIG. 7A , FIG. 7B , and FIG. 7C , and details will not be repeated here.

On the other hand, if the pointing path points to the display screen, the display device will control the zooming of the display screen according to the pointer movement information (A) (step S66).

Assume that FIG. 10A is the original display screen. If the user turns the scroll wheel toward the tail of the pen, and the pointer movement direction ( a1 ) is defined as the positive movement direction (+), then as shown in FIG. 10B , the content of the display screen will be zoomed out (zoom-out). Moreover, the display device will determine the ratio of the content of the display screen to be reduced according to the pointer movement amount (a2).

Similarly, if the user turns the scroll wheel toward the pen tip, and the pointer movement direction ( a1 ) is defined as a negative movement direction (-), then as shown in FIG. 10C , the content of the display screen will be enlarged (zoom-in). Also, the amount of pointer movement (a2) determines the scale at which the content of the display screen is enlarged.

Based on the above, the present invention can judge the placement posture of the optical pen according to the long axis of the casing, and then adjust the display screen to move vertically or not. The following uses Figure 11A and Figure 11B to summarize the correlation between the horizontal angle of the long axis and the movement mode of the display screen, wherein the dotted line in the horizontal direction represents the direction parallel to the horizontal plane, and the two thicker dotted lines represent the first horizontal angle threshold (α_th).

In FIG. 11A , when the optical pen 91 is respectively in the first placement posture P1, the second placement posture P2, and the third placement posture P3, the horizontal angles of its long axis are respectively the first long axis horizontal angle θ1, The second major axis horizontal angle θ2, the third major axis horizontal angle θ3; and these major axis horizontal angles (θ1, θ2, θ3) are all greater than the first horizontal angle threshold (α_th). Therefore, when the optical pen 91 assumes the first placement posture P1 , the second placement posture P2 , and the third placement posture P3 , the display device will move the display screen vertically and vertically according to the pointer movement information.

In FIG. 11B , when the optical pen 91 is respectively in the fourth placement posture P4, the fifth placement posture P5, the sixth placement posture P6, and the seventh placement posture P7, the horizontal angles of its major axes are respectively the fourth longest Axis horizontal angle θ4, fifth long axis horizontal angle θ5, sixth long axis horizontal angle θ6, seventh long axis horizontal angle θ7; and these long axis horizontal angles (θ4, θ5, θ6, θ7) are smaller than the first horizontal angle threshold (α_th). Therefore, when the optical pen 91 assumes the first placement posture P1, the second placement posture P2, the third placement posture P3, and the fourth placement posture P4, the display device will move the display screen horizontally according to the pointer movement information. or zoom adjustments.

For example, the first horizontal angle threshold (α_th) can be defined as 50 degrees. When the long axis horizontal angle is greater than 50 degrees, the display device will control the display screen to move vertically; and, when the long axis horizontal angle is less than 50 degrees , the display device will control the display screen to perform non-vertical movement.

The present invention can also provide an error interval (for example, plus or minus 5 degrees) with the first horizontal angle threshold. When the horizontal included angle of the major axis changes but is still within the error range, the original operation mode is maintained.

For example: if the user currently operates the optical pen to control the display screen of the display device to move horizontally, when the horizontal angle of the long axis increases from 40 degrees to 54 degrees, the horizontal movement is still maintained; until the long axis of the optical pen 81 is horizontal When the included angle continues to increase and exceeds 55 degrees, the display device changes to control the display screen to move vertically, and vice versa.

In addition to representing the arrangement information (B) by the long-axis horizontal angle, the present invention can also use other ways to define the arrangement information (B). Please refer to FIG. 12A , which is a schematic diagram representing the placement posture of the optical pen 42 by using the horizontal angle of the lateral axis. It defines the extension direction of the rotation axis of the scroll wheel 422 as the input unit lateral axis, therefore, the input unit lateral axis will be perpendicular to the pen body direction of the optical pen 42 .

The angle between the lateral axis of the input unit and the horizontal plane is further defined as the horizontal angle of the lateral axis, and the placement information (B) is represented by the horizontal angle of the lateral axis. Similarly, when combined with the pointer movement information (A) represented by the rotation direction and rotation amount of the scroll wheel 422, the display device can further control the display screen.

When the placement posture of the optical pen changes, the horizontal included angle of the lateral axis also changes accordingly. FIG. 12B illustrates an embodiment of the present invention, how to determine the user's operation type according to the horizontal angle of the lateral axis.

In this figure, it is assumed that the optical pen 42 is respectively in the first placement posture P1, the second placement posture P2, the third placement posture P3, and the fourth placement posture P4, and the horizontal angles of the lateral axes are respectively the first lateral The horizontal angle θ1 of the axis, the horizontal angle θ2 of the second lateral major axis, the horizontal angle θ3 of the third lateral axis, and the horizontal angle θ4 of the fourth lateral axis.

In FIG. 12B , when the placement posture of the optical pen 42 is the first placement posture P1 , the third placement posture P3 , and the fourth placement posture P4 in the figure, the horizontal included angle of the lateral axis is relatively small. That is, when the direction of the body of the optical pen 42 is placed closer to the vertical direction, the horizontal included angle of the lateral axis becomes smaller. Therefore, a second horizontal angle threshold (θ=β_th) can be defined. When the optical pen 42 is placed in a posture such that the horizontal angle of the lateral axis is smaller than the second horizontal angle threshold (θ<β_th), the display device will vertically display the display screen. move.

On the other hand, when the placement posture of the optical pen 42 is shown as the second placement posture P2 and the fifth placement posture P5 in the figure, the horizontal included angle of the lateral axis is relatively large. That is, when the direction of the body of the optical pen 42 is placed closer to the horizontal direction, the horizontal included angle of the lateral axis becomes larger. Therefore, a second horizontal angle threshold (θ=β_th) can be defined. When the optical pen 42 is placed in such a way that the horizontal angle of the lateral axis is greater than the second horizontal angle threshold (θ>β_th), the display device will perform a non-adjustable display on the display screen. Move vertically.

Therefore, in FIG. 12 , the lighter shading represents the non-vertical movement of the user using the roller of the optical pen 42 , and the darker shading represents the horizontal angle of the lateral axis during vertical movement. The dotted lines in the horizontal direction in the figure represent that the horizontal angle of the lateral axis is 0 degree, and the two thicker dotted lines represent the second horizontal angle threshold (β_th).

When the optical pen uses the horizontal angle of the lateral axis to represent the placement information, how the display device adjusts the display screen according to the rotation direction and rotation amount of the scroll wheel can be analogously described above, and will not be repeated here. It should be noted that the corresponding relationship between the control method of the input unit and the moving direction of the pointer and the moving amount of the pointer is not limited to the method defined above. For example: when the scroll wheel rolls towards the direction of the pen tip, it can also be defined as the positive movement direction of the pointer, and vice versa.

Although the foregoing embodiments assume that the input unit of the optical pen is a scroll wheel, the two directions that the scroll wheel rotates correspond to two opposite directions in the same dimension when the pointer moves, and the actual rotation amount of the scroll wheel corresponds to the pointer movement amount of the display screen . However, the input unit of the optical pen may also be a touchpad, a rocker switch, a key switch, etc. arranged on an X-axis-Y-axis plane. Wherein, the input unit extends along the Y axis, and the X axis is a lateral axis of the input unit.

Please refer to FIG. 13A , which is a schematic diagram of an optical pen using a strip-shaped touchpad 711 as an input unit. The long axis of the casing is defined as a direction parallel to the direction of the body of the optical pen 71 , and the indication path represents a direction parallel to the long axis of the casing and pointing to the pen tip. Furthermore, the lateral axis of the input unit is defined as a direction perpendicular to the direction of the body of the optical pen 71 .

The touch panel 711 can detect a touch gesture, and the movement direction of the touch gesture can be selected from one of a positive movement direction and a negative movement direction. When the optical pen 71 uses a touch panel as an input unit, the moving distance and moving direction of the pointer can be represented according to the moving distance and moving direction of the touch gesture.

Please refer to FIG. 13B , which is a schematic diagram of an optical pen using a rocker switch 721 as an input unit. The long axis of the casing is defined as a direction parallel to the direction of the body of the optical pen, and the indication path is parallel to the long axis of the casing and points to the nib of the optical pen. Furthermore, the lateral axis of the input unit is defined as a direction perpendicular to the direction of the body of the optical pen.

The seesaw switch 721 can generate a conduction signal in response to the pressing of the user, wherein the movement amount of the indicator corresponds to the length of time or the number of presses of the seesaw switch 721 . When the first half 721a of the seesaw switch 721 close to the tip of the pen is pressed, the positive movement direction is used as the index movement direction; when the second half 721b of the seesaw switch 721 close to the pen tip is pressed, the negative movement direction is taken as the index movement direction.

Please refer to FIG. 13C , which is a schematic diagram of an optical pen using a key switch 731 as an input unit. The long axis of the casing is defined as a direction parallel to the direction of the body of the optical pen, and the indication path is parallel to the long axis of the casing and points to the nib of the optical pen. Furthermore, the lateral axis of the input unit is defined as a direction perpendicular to the direction of the body of the optical pen.

If the key switch 731a that is closer to the pen tip is pressed, assuming that the conduction signal is in the first state, the moving direction of the pointer is defined as the positive moving direction.

Furthermore, if the key switch 731b that is relatively closer to the end of the pen is pressed, assuming that the conduction signal is in the second state, the moving direction of the pointer is defined as a negative moving direction.

In addition to determining the movement direction of the indicator according to the key switches 731a and 731b, the present invention can also determine the moving amount of the indicator according to the number of times or the time the user presses the key switches 731a and 731b.

In another application, the optical pen can also provide the function of modifying the input handwriting when the display device provides the writing or drawing function.

Please refer to FIG. 14 , which is a schematic diagram of the display system of the present invention. Wherein the display device is connected to the personal computer PC, and the drawing software (such as: the little painter in the Windows subsidiary application program) is being executed on the personal computer PC and the image file A (imagefile) is opened. Among them, there are stroke setting area and color setting area on the left side of the drawing software. The user can control the placement of the optical pen 143 so that the intersection position of the optical pen 143 and the display screen 142 stays in various areas on the left side of the display screen 142, and select the stroke or color of the input handwriting according to the desired setting type. The details are as follows:

In addition to displaying the indication pattern at the intersection position to prompt the user, the display device can also select a brush stroke pattern as the indication pattern when the user uses drawing software to write or draw.

Taking FIG. 15A as an example, the brush stroke setting area shows that the preselected brush stroke patterns provided by the drawing software include watercolor pens, paint brushes, rollers, and the like. Assume that the drawing software uses the pattern of the watercolor pen as the first brushstroke pattern; the pattern of the paint brush as the second brushstroke pattern; and the pattern of the roller as the third brushstroke pattern.

According to an embodiment of the present invention, when the intersection position stays in the stroke setting area and the user performs a dynamic operation on the optical pen (for example, swinging the optical pen back and forth), the stroke pattern of the brush can be changed correspondingly.

For example, if the user shakes the optical pen once, the first brush stroke pattern (watercolor pen) is selected; if the user shakes the optical pen twice, then the second brush stroke pattern (paint brush) is selected; When the user shakes the optical pen three times, the third brush stroke pattern (roller) is selected. In the same way, if the user shakes the optical pen again, the selected first brush stroke pattern (watercolor pen) will be restored, and so on.

In other words, when the user selects a brush stroke pattern, the display system of the present invention allows the user to directly change the selected brush stroke pattern through the operation of the optical pen, without repeatedly changing the selected brush stroke pattern through the drawing software. The present invention judges whether the user shakes the optical pen, and determines the brush stroke pattern currently selected according to the times of shaking the optical pen.

When realizing this function, the present invention can set an acceleration sensing unit in the optical pen to sense the acceleration of the pen-shaped casing moving in space. When the optical pen is shaken, shaken or swung due to the dynamic operation behavior of the user, the acceleration sensing unit generates a housing vibration signal. Afterwards, the vibration signal of the shell is transmitted to the display device through the transmission unit electrically connected with the acceleration sensing unit.

As above, the receiving unit of the display device is connected to the transmitting unit of the optical pen, so that the display device first receives the housing vibration signal through the receiving unit. Afterwards, the display unit changes the appearance of the indication pattern according to the number of times the housing vibration signal is received.

For the same reason, please refer to FIG. 15B , which provides a schematic diagram of the six sequential candidate colors as the trajectory of the optical pen. The user can control the optical pen and stop the intersection position in the color setting area. In addition, the color setting area provides six preset sequential candidate colors. As the user performs dynamic operations on the optical pen, the display screen will also change the display attributes of the indication pattern and the input handwriting.

That is, the user selects the color that the user wants to use by using the number of times the optical pen is swung. Similar to the stroke setting method, the user can repeatedly select the color to be used by using the number of times the optical pen is swung. After the user completes the drawing or image modification through the operation of the optical pen, the drawing software can provide the function of storing the input handwriting.

Referring to FIG. 16 , it is a schematic diagram of the optical pen 161 sensing the user's dynamic operation of the present invention. The tail of the optical pen 161 includes a first switch unit 161c and a second switch unit 161a on the housing side.

Wherein, the first switch unit 161c is regarded as a locking unit, and is electrically connected to the gravity sensing unit and the transmission unit.

When the user wishes to set the display attribute of the input handwriting, the locking unit is not activated first, and the acceleration sensing unit continuously senses the dynamic operation of the user. That is to say, the display attribute of the input handwriting is determined according to the area where the intersection position stays and the number of times the user flicks.

After the user decides the stroke and color of the input handwriting, he can press the first switch unit 161c. At this time, the locking unit is activated, which means that the optical pen 161 no longer detects the dynamic operation of the user. After the locking unit is activated and generates a locking signal, the acceleration sensing unit also stops outputting the vibration signal of the casing.

Of course, if the user wishes to change the display attribute of the input handwriting again after writing a paragraph, he can press the first switch unit 161c again, that is, stop the activation of the locking unit. After that, repeat the aforementioned selection and setting process, and restart the locking unit after the selection is completed.

Moreover, the second switch unit 161a is regarded as an enabling unit, and is electrically connected to the transmitting unit, which generates an enabling signal due to a user's operation.

When the enabling unit is pressed, the enabling unit generates an enabling signal, and the enabling signal is transmitted to the display device. When the enabling unit is pressed, it means that the user wishes to set the drawing software in the writing mode. That is to say, in addition to adjusting the position of the indication pattern due to the change of the intersection position, the display unit also modifies the input trajectory correspondingly.

Please refer to FIG. 17A , which represents the operation when the drawing software is in the non-writing mode when the enabling unit is not pressed. At this time, the display device only displays the current intersection position with a pointer pattern. FIG. 17A illustrates the continuous moving process of the intersecting position with a dotted line trajectory. The display screen 171 will not display the dotted line trajectory, and the drawing software will not record the above dotted line trajectory into the currently opened image file.

Please refer to FIG. 17B , which represents the operation of the drawing software in writing mode when the enable unit is pressed. At this time, in addition to displaying the indication pattern, the display device will also display the trajectory of the change of the intersection position. Assume that the user selects the third brush stroke image (drum) and the first round of candidate colors. Then the solid line track in Fig. 17B represents the continuous moving process of the intersection position. As can be seen from the figure, the display screen 172 will display a wider solid line track, and the drawing software will also modify and edit the currently opened image file according to the above solid line track, that is, record the above solid line track to the currently opened image file.

Although the aforementioned preferred embodiment illustrates how the drawing software determines how to change the input handwriting according to the number of times the optical pen is swung back and forth, but in actual application, the type of dynamic operation sensed by the optical pen is not limited to the front and back swings. All methods such as rotation and swing can also be used as the source of judging the vibration signal generated by the housing of the optical pen.

Furthermore, after the user determines the stroke or color (for example, the third brush stroke and the first round candidate color), when pressing the enable unit to enter the writing mode, the width of the line can be determined by rotating the pen body and changes in brightness. The details are as follows:

Referring to FIG. 18 , it is a schematic diagram of sensing the rotation range of the optical pen. This figure represents that the user can rotate the optical pen 161 clockwise or counterclockwise with the central axis as the rotation center. The width or brightness of the input handwriting can be determined according to the extent to which the user rotates the optical pen 161 .

Please refer to FIG. 19 , which is a schematic diagram of the user moving and turning the optical pen while operating the optical pen. For example, when the user operates the optical pen 181 to draw the dotted line trajectory as shown in the figure, the user not only moves the optical pen 181 from left to right, but also makes the optical pen 161 center axis as the center of rotation to make the optical pen generate turn. Therefore, when the second switch unit 181 a originally displayed on the left side of the dotted line faces up the screen, it has turned to the bottom of the figure when it reaches the right end of the dotted line.

The present invention further provides a method for adjusting the width of the input handwriting according to the turning direction of the optical pen during the writing process, which is described in detail as follows.

Please refer to FIG. 20A , which is a schematic diagram corresponding to input handwriting with different widths according to the direction of the optical pen.

Here, it is assumed that the user operates the optical pen 181 to write a horizontal S-shaped track. Assuming that when the user operates the optical pen 181, in addition to moving the position of the optical pen 181 in the three-dimensional space so that the optical pen 181 moves along the dotted line in the figure, the body of the optical pen 181 will also change with time. change its direction.

It can be seen from the figure that when the user operates the optical pen 181 , the width of the input handwriting displayed on the display screen 180 will also be adjusted synchronously. For example: corresponding to the turning directions of the optical pen 181 at t1 , t3 , and t5 , the input handwriting displayed on the display screen 180 has wider, thinner, and wider widths, respectively.

Referring to FIG. 20B , it is a schematic diagram of the section of the corresponding optical pen at different time points during the writing process in FIG. 20A .

In order to distinguish the rotation states of the optical pen at different time points, it is assumed here that the preset cut plane is: the cut plane of the enabling unit of the optical pen on the surface of the optical pen. Certainly, the way of defining the preset cut plane is not limited thereto, for example, the preset cut plane may also be defined as a cut plane at the position of the roller of the optical pen on the surface of the optical pen, and the like. Furthermore, in this embodiment, the included angle between the preset cut plane of the optical pen 181 and the vertical line is defined as a vertical included angle.

At the first time point t1 , if the cut surface of the optical pen 181 is viewed from the rear side of the optical pen 181 , the enabling unit 181 a is located relatively above the optical pen 181 . At this time, the vertical angle between the preset cut plane of the optical pen 181 and the vertical line is 90 degrees. It is assumed here that the input handwriting has a relatively wide width setting when the vertical angle presents 90 degrees. For example: assume that the width of the input handwriting is set to be 100% at the first time point t1.

At the second time point t2 , if the cut surface of the optical pen 181 is viewed from the rear side of the optical pen 181 , the enabling unit is located at the relatively upper right position of the optical pen 181 . At this time, the vertical angle between the preset cut plane of the optical pen 181 and the vertical line presents 45 degrees. Here, the display ratio of the width setting of the input handwriting may be reduced to 75% at the second time point t2.

At the third time point t3 , if the cut surface of the optical pen 181 is viewed from the rear side of the optical pen 181 , the enabling unit 181 a is located at a relatively right side of the optical pen 181 . At this time, the vertical angle between the preset cut plane of the optical pen 181 and the vertical line presents 0 degree. The display ratio of the width setting of the input handwriting may be reduced to 50% at the third time point t3.

At the fourth time point t4 , if the cut surface of the optical pen 181 is viewed from the rear side of the optical pen 181 , the enabling unit 181 a is located at the relatively upper right position of the optical pen 181 . At this time, the vertical angle between the preset cut plane of the optical pen 181 and the vertical line presents 45 degrees. Here, the display ratio of the track width at the fourth time point t4 may return to 75%.

At the fifth time point t5 , if the cut surface of the optical pen 181 is viewed from the rear side of the optical pen 181 , the enabling unit 181 a is located relatively above the optical pen 181 . At this time, the vertical angle between the preset cut surface of the optical pen 181 and the vertical line returns to 90 degrees, and the input handwriting on the display screen has a wider width again. At this time, the display ratio of the track width at the fifth time point t5 may return to 100%.

The optical pen of the present invention can use the gravity sensing unit to sense the vertical angle and obtain the vertical angle information, and transmit the vertical angle information to the display device through the transmission unit. After receiving the vertical angle information through the receiving unit, the display device provides it to the drawing software on the PC side, so that the drawing software on the PC side can refer to this information to adjust the display properties of the input handwriting.

Please refer to FIG. 21 , which is a schematic diagram illustrating how the angle change between the preset cut plane of the optical pen and the vertical line affects the setting of the handwriting width.

In this figure, the first column represents the position of the optical pen 181 when looking forward from the side rear of the optical pen 181; The relationship between the vertical line and the preset cut plane when presenting different postures; and, the third column illustrates the input handwriting when the width changes. In addition, the fourth column shows how the width of the input ink changes according to the vertical angle.

Suppose the setting of the drawing software is: when the optical pen 181 is at the first preset angle θ1, the width of the input handwriting is the first width W1; and, when the vertical angle is the second preset angle θ2, input The width of the handwriting is the second width W2.

When the user operates the optical pen 181, there is a first angle difference Δθ1 between the vertical angle θ of the optical pen 181 and the first preset angle θ1, and there is a second angle difference between the vertical angle θ and the second preset angle θ2 value Δθ2, and the width W of the input handwriting is determined according to the first width W1, the second width W2, and the first angle difference Δθ1 and the second angle difference Δθ2. For example:

$\mathrm{<span\; class="notranslate">\; W</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; |</span>}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}$

The first line of FIG. 21 assumes that the tail of the optical pen 181 is viewed from the direction of the pen tip, and the first placement posture of the optical pen 181 makes the enabling unit relatively located at the twelve o’clock position, which represents between the preset cut plane and the vertical line. The included angle is 90 degrees. In this way, the first preset angle is 90 degrees, the first angle difference Δθ1 is 0 degrees, and the second angle difference Δθ2 is 90 degrees. When the optical pen 181 exhibits this posture, the input handwriting corresponding to the optical pen 181 should have a first width W1, that is,

$\mathrm{<span\; class="notranslate">\; W</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}}{<span\; class="notranslate">\; |</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; \&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; |</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; 90</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; 0</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; .</span>$

On the other hand, the third row of FIG. 21 shows that if the second placement posture of the optical pen 181 makes the enabling unit relatively located at the three o'clock position, it means that the angle between the preset cut plane and the vertical line is 0 degree. In this way, the second preset angle is 0 degrees, at this time, the first angle difference is 90 degrees, and the second angle difference Δθ2 is 0 degrees. When the optical pen 181 exhibits this posture, the input handwriting corresponding to the optical pen 181 should have a second width W2, that is,

$\mathrm{<span\; class="notranslate">\; W</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 2</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; \&Delta;\&theta;</span>}\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; 0</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; *</span>\frac{\mathrm{<span\; class="notranslate">\; 90</span>}}{\mathrm{<span\; class="notranslate">\; 90</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; W</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; .</span>$
