FIG. 1 is a block diagram of a computer device according to an embodiment of the invention.

The electronic device 100 can be, for example, a personal computer, a server, or a portable device. The electronic device 100 includes an arithmetic unit 110, a storage unit 130, an input device 140, and a display 150. The computing unit 110, the storage unit 130, the input device 140, and the display 150 communicate with each other through the bus 115.

The storage unit 130 includes a volatile memory 131 and a non-volatile memory 132. The non-volatile memory 132 is used to store an operating system 133 and an application program 134. The non-volatile memory 132 may be, for example, a hard disk drive, a solid-state disk, a flash memory, or a read-only memory (read-only). only memory), but the present invention is not limited to this. The volatile memory 131 may be a random access memory, such as a static random access memory (SRAM) or a dynamic random access memory (DRAM), but the invention is not limited thereto.

In one embodiment, the computing unit 110 reads the operating system 133 and the application program 134 from the non-volatile memory 132 to the volatile memory 131 and executes The application program 134 can display a graphical user interface (GUI) on the display 150, and the graphical user interface can include a plurality of objects and a cursor.

The input device 140 is used for the user to perform corresponding operations on the graphical user interface. The input device 140 can be, for example, a mouse, a trackball, or a keyboard, etc., but the invention is not limited thereto.

Provide a user interface for users to watch. In some embodiments, the display 150 can be integrated with a touch device to form a touch screen, and the user can use his finger or stylus to perform touch actions on the touch panel to use the graphics Operate on the user interface.

FIG. 2A is a schematic diagram of selecting a target object based on the shortest distance according to an embodiment of the present invention.

Please refer to FIG. 1 and FIG. 2A at the same time. In one embodiment, the application program 134 executed by the computing unit 110 is, for example, a modular computer system management program, which can display the graphical user interface 200 on the display 150, wherein The graphical user interface 200 includes a cursor 210 and a plurality of objects 220, 230, and 240A-240D. Each object 220 corresponds to a first type module, and each object 230 corresponds to a second type module. The first type module has two slots, for example, two smaller-sized modules. Target object, and the second type module has a slot, such as visual It is a larger target object. Objects 240A~240D, for example, correspond to the option of "Expansion Module", which means that the user can add the selected module (for example, the first type module, the second type module, or other types of modules) respectively To the far right of the module row 201~204.

For example, as shown in Figure 2A, the objects 220, 230, and 240A~240D in the graphical user interface 200 can be divided into four module rows 201~204, of which the module row 201 is composed of five objects 220 and The module row 202 is composed of an object 220, an object 230, and an object 240B; the module row 203 is composed of an object 220, seven objects 230, and an object 240C; the module row 204 is composed of an object 220, an object 230, and an object 240B. It is composed of an object 220 and an object 240D.

In one embodiment, the coordinates on the screen displayed by the display 150 are, for example, the X axis is positive to the right, and the Y axis is positive to the bottom. The arithmetic unit 110, for example, continuously obtains the coordinates of the cursor 210 on the screen displayed on the display 150, for example, based on the cursor position P0 of the vertex of the cursor 210, and the coordinates are, for example, (x0, y0). If the user selects an expansion module (for example, object 220 or 230) on the graphical user interface 200, and the expansion module can be added to one of the objects 240A~240D, for example, to be listed in the corresponding module row An expansion module (for example, object 220 or 230) is added to the rightmost of 201~204.

The computing unit 110 calculates the Euclidean distance between the cursor position P0 of the cursor 210 and the object positions of the objects 240A to 240D, and selects the object with the shortest distance as the target object. In this embodiment, there is the shortest distance between the cursor position P0 of the cursor 210 and the object position of the object 240C, so the object 240C will be selected as the target object. Different image effects such as bright, flashing, reverse white, etc., indicate that the object 240C is the selected target object, but the present invention is not limited thereto.

If the user selects a computer module on the graphical user interface 200, for example, it can correspond to one of the slots of the object 220, then the empty slots in each object 220 in the graphical user interface 200 will be regarded as For different objects, the computing unit 110 calculates the distance between the cursor position P0 of the cursor 210 and each object, and selects the object with the shortest distance as the target object.

It should be noted that Figure 2A is used to illustrate how to calculate the object with the shortest distance from the cursor 210, and this calculation method will be applied to one of the prediction methods for selecting the target object in the present invention. The details will be detailed After.

FIG. 2B is a schematic diagram of selecting a target object by weighting according to coordinate axes according to an embodiment of the present invention.

In one embodiment, if the user also selects an expansion module (for example, an object 220 or 230) on the graphical user interface 200, and the expansion module can be added to one of the objects 240A~240D, for example, An expansion module (for example, an object 220 or 230) can be added to the rightmost side of the corresponding module row 201~204. However, the position where the user wants to add the expansion module is at object 240B, and the position of the cursor 210 moves at the cursor positions P1~P3 on the right side of the user interface 200. If the shortest distance calculation method is used in Figure 2A, The objects with the shortest distance from the cursor 210 calculated by the arithmetic unit 110 are all the object 240C, and the object 240B cannot be selected. Therefore, in this situation, the computing unit 110 uses the coordinate axis weighting calculation method.

For example, when the user uses the input device 140 to move the cursor 210, the computing unit 110 continuously calculates the cursor position, cursor speed, and movement vector of the cursor 210 on the screen displayed on the display 150. Then, the arithmetic unit 110 may calculate a weighted movement vector of the cursor 210, and according to the movement of the cursor 210 according to the weighted movement vector, select an object having the shortest distance from the moved cursor 210 in a specific direction as the target object.

In detail, as shown in Figure 2B, according to the arrangement of the module rows 201~204 in the graphical user interface 200, the computing unit 110 can set the first weight of the movement vector of the cursor 210 in the horizontal direction to 0. And set the second weight in the vertical direction to 1. In addition, the computing unit 110 may also determine that the specific direction is the horizontal direction according to the arrangement of the module rows 201 to 204. It should be noted that at this time, because of the arrangement of the module rows 201 to 204, the movement of the cursor 210 in the horizontal direction does not affect the selection of the object, so the computing unit 110 may not consider the movement of the cursor 210 in the horizontal direction.

For example, when the cursor 210 is located at the cursor position P1 after moving, for example, the coordinates are (x1, y1), the vertical distance between the cursor 210 and the object 240C is 0, and the object 240C is also the cursor 210 in a specific direction (ie horizontal Direction) The object with the shortest distance. Therefore, the computing unit 110 selects the object 240C as the target object.

Similarly, when the cursor 210 is located at the cursor position P2 after moving and its coordinates are (x2, y2), the vertical distance between the cursor 210 and the object 240B is 0, and the object 240B is also the cursor 210 in a specific direction (ie, the horizontal direction). ) The object with the shortest distance, that is, the computing unit 110 will select the object 240B as the target object. When the cursor 210 is located at the cursor position P2, although there is the shortest distance between the object 240C and the cursor 210 However, the computing unit 110 will still select the object 240B as the target object according to the calculation method of the coordinate axis weighting.

It should be noted that Figure 2B is used to illustrate how to use the coordinate axis weighting method to calculate the object with the shortest distance from the cursor 210 in a specific direction, and this calculation method will be applied to the prediction method of selecting the target object in the present invention. In one case, the details will be detailed later.

FIG. 2C is a schematic diagram of selecting a target object according to a reference position and a movement vector according to an embodiment of the present invention.

In one embodiment, the objects 2201 to 2204 are similar to the object 220 in Figure 2A, and the distance D between the cursor 210 and each slot of the objects 2201 to 2204 (which can be regarded as objects) is greater than a predetermined distance Dt. Each object 2201-2204 has two slots respectively. Among the objects 2201-2204, for example, only the object 2202 has an empty slot 223, the object 2203 has an empty slot 222, and the object 2204 has an empty slot 221. In addition, the right side of the dotted line 250 marked in the graphical user interface 200 means that the distance D between the cursor 210 and each slot of the objects 2201-2204 (all can be regarded as objects) is greater than a predetermined distance Dt, and the left side of the dotted line 250 That is to say, the distance D between the cursor 210 and each slot of the objects 2201-2204 (which can be regarded as objects) is less than or equal to a predetermined distance Dt.

If the slot 221 was originally one of the empty slots in the object 2204, and the user had selected the slot 221 corresponding to the object of a computer module on the graphical user interface 200 in the previous operation, and set the computer module The object is inserted into the slot 221. That is, the slot 221 can be called the last selected object. Corresponding to the large moving speed V of the cursor 210 At a speed threshold Vt, the computing unit 110 can use the previously selected object (ie the slot 221) as a reference and refer to the movement vector of the cursor 210 to select the object with the shortest distance as the target object.

For example, when the cursor 210 moves from the cursor position P4 to the cursor position P5, and the speed V of the cursor 210 is greater than the speed threshold Vt, the computing unit 110 will, for example, use the previously selected object (ie the slot 221) as a reference and refer to it The movement vector P 4 P 5 selects the slot 222 in the object 2203 as the target object.

Next, when the cursor 210 moves from the cursor position P5 to the cursor position P6, and the speed V of the cursor 210 is greater than the speed threshold Vt, the computing unit 110 will, for example, use the previously selected object (ie slot 221) as a reference, and then refer to the movement vector P 4 P 5+ P 5 P 6 takes the slot 223 in the selected object 2202 as the target object.

FIG. 2D is a schematic diagram of selecting a target object based on the shortest distance in the embodiment of FIG. 2C of the present invention.

As shown in FIG. 2D, when the cursor 210 moves to the left of the dotted line 250, the computing unit 110 selects the target object according to the shortest distance between the cursor 210 and the cursor 210. For example, similar to the method in FIG. 2A, when the cursor 210 moves to the position P7, the object 224 will have the shortest distance from the cursor 210. Therefore, the computing unit 110 selects the object 224 as the target object. When the cursor 210 moves to the position P8, although the distance between the object 222 and the object 223 and the cursor 210 is quite close, the computing unit 110 still calculates the shortest distance between the object 223 and the cursor 210. Therefore, the computing unit 110 selects the object 223 as the target object.

It should be noted that, in the embodiments in Figures 2A to 2D, a modular computer system management program is used as an example for description, and the present invention is not limited to this. For example, the arrangement of the objects in the graphical user interface may be different from the row arrangement in Figures 2A~2D, and the computing unit 110 can be based on the arrangement of the objects in the graphical user interface. Determine the weight of the movement vector of the cursor in the horizontal direction and the vertical direction, and a specific direction.

In one embodiment, when the objects in the graphical user interface are arranged in a straight line from left to right, the computing unit 110 can set the weight of the movement vector of the cursor in the vertical direction to 0, and move the cursor The weight of the vector in the horizontal direction is set to 1, which means that the movement of the cursor in the vertical direction is not considered.

FIG. 3A is a flowchart of a method for selecting a target object according to an embodiment of the present invention.

Please refer to FIGS. 1 to 3 at the same time. In step S310, a plurality of objects and a cursor are displayed on the display 150 of the electronic device 100.

In step S320, a movement speed and movement vector of a cursor, a cursor position, and a plurality of object positions of the objects are obtained. For example, each object 220 and 230 shown in FIG. 2A has a corresponding slot, and each slot can also be regarded as an object, and the object position of each object can be, for example, the coordinates in the image displayed by the display 150 (x,y) means.

In step S330, when the cursor position and the object positions meet a predetermined condition, it is determined whether there is a previously selected object. For example, the aforementioned predetermined condition is, for example, that the position of the cursor and the positions of the objects are greater than a predetermined distance, for example, in the 2C The right half of the dotted line 250 in the figure indicates that the cursor position and the positions of the objects are greater than the predetermined distance.

In step S340, when the currently selected object exists and the moving speed of the cursor is greater than a speed threshold, the previously selected object is used as a reference and the movement vector is referred to, and then the object with the shortest distance is selected as a target object. For example, please refer to the embodiment in FIG. 2C, where the slot 221 is, for example, the object selected last time. When the cursor 210 moves from the cursor position P4 to the cursor position P5, and the speed V of the cursor 210 is greater than the speed threshold Vt, the computing unit 110 will, for example, use the previously selected object (ie slot 221) as a reference and refer to the movement vector P 4 P5 takes the slot 222 in the selected object 2203 as the target object. Next, when the cursor 210 moves from the cursor position P5 to the cursor position P6, and the speed V of the cursor 210 is greater than the speed threshold Vt, the computing unit 110 will, for example, use the previously selected object (ie slot 221) as a reference, and then refer to the movement vector P 4 P 5+ P 5 P 6 takes the slot 223 in the selected object 2202 as the target object.

FIG. 3B is a flowchart of a prediction method for selecting a target object according to another embodiment of the present invention.

Steps S310-S330 in the flow in Figure 3B are similar to steps S310-S330 in Figure 3A. The difference between the flow in Figure 3A and Figure 3B is that step S350 is executed after step S330 in Figure 3B.

Please refer to Figure 2B and Figure 3B at the same time. In step S350, the currently selected object does not exist, calculate one of the weighted movement vectors of the cursor, and select a cursor in a specific direction and after the movement according to the weighted movement vector of the cursor The object with the shortest distance is used as the target object.

For example, when the currently selected object does not exist, the computing unit 110 cannot use the previously selected object as a reference to predict the target object. At this time, the computing unit 110 determines the target object based on the coordinate axis weighting method. For example, it can determine the first weight of the weighted movement vector in the horizontal direction and the vertical direction according to the arrangement of the objects in the graphical user interface 200 The second weight can determine the specific direction corresponding to the arrangement of the objects. In the embodiment of FIG. 2B, the specific direction is, for example, the horizontal direction, and when the cursor 210 is located at the cursor position P2 after moving, the vertical distance between the cursor 210 and the object 240B is 0, and the object 240B is the cursor 210 in the specific direction The object with the shortest distance (ie in the horizontal direction) means that the computing unit 110 will select the object 240B as the target object. When the cursor 210 is located at the cursor position P2, although there is the shortest distance between the object 240C and the cursor 210, the computing unit 110 still selects the object 240B as the target object according to the calculation method of the coordinate axis weighting.

Figures 4A-4B are detailed flowcharts of a prediction method for selecting a target object according to an embodiment of the present invention.

Please refer to Figures 1, 2 and 4 at the same time. In step S402, the user operates the cursor. For example, the user can control the movement of the cursor on the graphical user interface through the input device 140, or control the cursor on the graphical user interface by touch operation through the display 150 (such as a touch screen) Mobile.

In step S404, the moving speed, the moving vector and the position of the cursor, and the multiple object positions of the objects are obtained. For example, when the user controls and operates the cursor, the arithmetic unit 110 can obtain or calculate the movement speed and movement of the cursor. Motion vector and cursor position. In addition, the graphical user interface also includes a plurality of objects, and the computing unit 110 can obtain the object position corresponding to each object.

In step S406, it is determined whether the distance D between the cursor and each object is greater than a predetermined distance Dt. If the distance D between the cursor and each object is greater than the predetermined distance Dt, step S408 is executed. If the distance D between the cursor and each object is not all greater than the predetermined distance Dt, step S412 is executed. For example, the right half of the dotted line 250 in Figure 2C means that the cursor position and the object positions are both greater than a predetermined distance, and the left half of the dotted line 250 means that the cursor position and the object positions are not both greater than the predetermined distance. distance.

In step S408, it is determined whether the previously selected object exists. If the previously selected object exists, step S410 is executed. If the previously selected object does not exist, step S420 is executed. For example, if the previously selected object exists, the computing unit 110 can use the previously selected object as a reference, and refer to the movement vector of the cursor to quickly calculate the target object to be selected. If the previously selected object does not exist, the target object to be selected needs to be calculated by weighting the coordinate axes according to different object arrangements.

In step S410, it is determined whether the moving speed V of the cursor is greater than the speed threshold Vt. If the moving speed V of the cursor is greater than the speed threshold Vt, step S424 is executed. If the moving speed V of the cursor is less than or equal to the speed threshold Vt, step S426 is executed. For example, if the moving speed V of the cursor is greater than the speed threshold Vt, it means that the user wants to quickly select the desired target object. Therefore, the previous selected object can be used as a reference, and the moving vector of the cursor can be referred to to quickly calculate the selected object. The target object.

In step S412, the object with the shortest distance is selected. For example, the left half of the dotted line 250 in Figure 2C represents the position of the cursor and the position of the objects Not all are greater than the predetermined distance. Because the cursor position of the cursor and the distance between each object are quite close, the computing unit 110 still needs to calculate the object with the shortest distance to the cursor as the target object.

In step S414, it is determined whether the selected object hits. If the selected object hits, the process ends. If the selected object does not hit, step S416 is executed. For example, although the computing unit 110 has selected the object with the shortest distance from the cursor, the user may not have moved the cursor near the object to be selected. Therefore, the input device 140 still needs to be used to continue to control the cursor movement.

In step S416, it is determined whether the previously selected object exists. If the previously selected object exists, step S418 is executed. If the previously selected object does not exist, return to step S402. For example, if the previously selected object exists, but the user does not select the desired target object, step S418 is executed at this time to clear the previously selected object.

In step S420, the weights of different directions are determined according to the arrangement of the objects, and the weighted movement vector of the cursor is calculated. For example, the arrangement of the objects in the graphical user interface may be different from the row arrangement in Figures 2A~2D, and the computing unit 110 can be based on the arrangement of the objects in the graphical user interface. Determine the weight of the movement vector of the cursor in the horizontal direction and the vertical direction, and a specific direction. In another embodiment, when the objects in the graphical user interface are arranged in a straight line from left to right, the computing unit 110 can set the weight of the movement vector of the cursor in the vertical direction to 0, and set the weight of the cursor in the vertical direction. The weight of the movement vector in the horizontal direction is set to 1, which means that the movement of the cursor in the vertical direction is not considered.

In step S422, the object with the shortest distance in a specific direction is selected. For example, in the embodiment of Figure 2B, the specific direction is, for example, the horizontal direction, and when the cursor 210 is located at the cursor position P2 after moving, the vertical distance between the cursor 210 and the object 240B is 0, and the object 240B is the cursor The object 210 has the shortest distance in a specific direction (ie, the horizontal direction), which means that the computing unit 110 will select the object 240B as the target object. When the cursor 210 is located at the cursor position P2, although there is the shortest distance between the object 240C and the cursor 210, the computing unit 110 still selects the object 240B as the target object according to the calculation method of the coordinate axis weighting.

In step S424, after the previously selected object is used as a reference and the movement vector is referred to, the object with the shortest distance is selected. In step S426, it is determined whether the selected object hits. If the selected object hits, the process ends. If the selected object does not hit, step S428 is executed.

For example, although the computing unit 110 may have determined the object to be selected in different steps (such as step S422 or S424), the selected object may not be the object that the user wants to select. At this time, step S428 needs to be executed to save the currently selected object. For example, in the embodiment of FIG. 2C, when the cursor 210 moves from the cursor position P4 to the cursor position P5, but the target object selected by the computing unit 110 at this time is the slot 222, but it is not what the user wants to select object. Therefore, the computing unit 110 retains the selected slot 222, and the process returns to step S402, and allows the user to continue operating the cursor movement to select the desired target object.

In detail, the prediction method for selecting the target object in the present invention allows the user to select the desired object without moving the cursor a long distance on the screen The target object can be switched according to the distance between the cursor and the object, as well as the movement speed and movement vector of the cursor, so as to switch between different prediction modes (such as the shortest distance, the weight of the coordinate axis, the previous selected object as the reference, etc.). Quickly predict the target object the user wants.

It should be noted that the graphical user interface is used for the description in the embodiments in Figures 2 to 4, but the prediction method for selecting the target object in the present invention is not limited to the two-dimensional graphical user interface. For example, the prediction method for selecting the target object in the present invention can also be applied to augmented reality, virtual reality, human-computer interaction, and wearable technology, and the cursor can be regarded as a use The hand or a specific object of the person. For example, the user can control the cursor to move in a three-dimensional space, and the position of an object in the three-dimensional space can be represented by (x, y, z) three-dimensional coordinates, for example. In addition, the predetermined distance set in the two-dimensional graphical user interface can be represented by a plane or a spherical surface in the three-dimensional space, for example.

When the arithmetic unit 110 calculates the movement vector of the cursor, it is also calculated based on the movement vector in the three-dimensional space, and the weighted movement vector can be determined according to the arrangement of the objects in the three-dimensional space. The first weight, the second weight, and the third weight, and the specific direction corresponding to the arrangement of the objects. In addition, the arithmetic unit 110 can calculate the weighted movement vector according to the similar method in the embodiment of the two-dimensional graphical user interface, and determine the object with the shortest three-dimensional distance in a specific direction as the target object.
