Description of the Invention: [Technical Field of the Invention] The present invention relates to a command input method and apparatus. [Prior Art] Among many forms of command input devices, touch devices have become common electronic components today, and can be found, for example, in touchpads of notebook computers, or as electronic teller machines, personal digital assistants, electronic dictionaries. Such as touch screen or touch panel and so on. Currently, various touch devices sense the position of the touch in a resistive or capacitive manner. The resistive drive principle is to use the voltage drop method to find the coordinate axis. When the resistive touch screen is touched, the voltage drop occurs due to the loop being turned on, and in the horizontal and vertical directions of the panel, with the position The voltage drop is different, so the controller can calculate the coordinates based on the voltage drop. The capacitive structure is based on ITO (Indium Tin Oxide). The driving principle is to discharge at the four corners of the ITO glass to form a uniform electric field on the surface. When a conductive object, such as a finger, makes a trace of current. The conduction drain' controller calculates the ratio of current loss and further calculates the X-axis and Υ-axis coordinates. In addition to resistive or capacitive touch devices, other command input devices are disclosed in U.S. Patent Nos. 6,057,540; 6,621,483; 6,677,929, respectively. In the above various command input devices, the track movement is usually used to generate mobile information (for example, moving cursors), and the "click/double click" touch mode is used to generate control information (for example, opening a menu, selecting an option in a menu, etc.). 5 200931318 The present invention additionally provides a method for generating sugar control, which can generate richer control commands, and provides an appropriate occasion for the use of a "click/double click" position as a control order. Transfer plan. SUMMARY OF THE INVENTION An object of the present invention is to provide an instruction input method and apparatus which generate control information in a different manner from the prior art. For the above purposes, in one aspect, the present invention provides - the command input device includes: means for receiving the input signal; and changes in the horizontal and vertical directions according to the two input signals before and after A processing circuit that generates control information by quantity. In addition, according to another aspect of the present invention, there is also provided a command output method comprising: receiving an input signal; comparing a change amount of the two input signals in a horizontal direction and a vertical direction; and generating a control information according to the comparison result. When the upper position and the square are used, the direction of the change in the horizontal direction and the vertical direction may be first generated, and then the direction of the rotation and the direction of rotation may be determined according to the change of the direction of the direction. In addition, more control information can be generated based on the magnitude of the rotation. The purpose, technical contents, features and effects achieved by the present invention will be more readily understood by the detailed description of the embodiments. [Embodiment] 6 200931318 The method and device for inputting the present invention can be applied to a touch panel, a touch screen portable electronic device such as a mobile phone, a personal digital assistant (PDA) - his Xiaotu towel. The device and method of the present system are not in vain and need to be controlled. However, one of the objects of the present invention is to provide a solution to the existing touch device, and therefore the term "touch" is still used. ^ In the "resistive, electric valley or optical command input device, the tracking direction must be judged. Figure 1 shows the possible state of the invention when applied to a mobile phone." In this embodiment The optical input mode is adopted. The mobile phone has a casing 11 and an instruction input position m is provided on the casing 11. In the small portable electronic device, the size of the command input position 111 can be designed to be relatively small, for example, a finger. All of them are obscured or obscured. As shown in Fig. 2, the user can move the finger through the optical component and the circuit 3 to receive the fingerprint image of the command input position 111 by using the finger 5〇 at the command input position (1). After being converted into an electronic signal, the processing circuit 40 processes the mobile information and the control information. In the case of generating the mobile information, for example, the image of the various square-side commands of the Kawasaki County can be input to the image at the position ill. The change 'can generate corresponding mobile information. _ After generating the mobile information, the control information can be generated according to the mobile information. In the present invention, firstly, the up and down directions can be generated according to the moving direction of the trajectory. For example, the amount of information in the four directions can be defined as follows (see Figure 3): • Although |ΔΧ| > lAY+thl and ΛΧ is the positive direction state is 81 (where) • Although | ΔΧ | > | Δγ+th | and ΛΧ is negative... The direction state is S3(XN) • Preparation | ΔΥ | > | AX+th | and Δγ is positive... The direction state is S4(YP) 200931318 • When |AY|>|AX+th| and ΔΥ is negative... The direction state is S2(YN) where ΔΧ and ΔΥ are respectively indicated between the two points before and after, the χ coordinate and the γ coordinate The change value; th is the safety critical value, indicating that the absolute value difference between ^ and ^丫 must be above the safety threshold, and is considered valid; XP, XN, YP, YN represent the positive X coordinate direction, the negative X coordinate direction, The positive γ coordinate direction and the negative Υ coordinate direction. The fourth figure exemplifies the flow of the above algorithm. First, after capturing the images at two time points in step 4〇1 ❹ ,, compare them in step 402 to determine the Χ coordinates and The coordinates of the coordinates are determined by the process of tilting 403 to 410. The process in the state 1 is not the only implementation. The steps in the process are obviously interchangeable. The direction state determined by the manner can be used, for example, to switch between menus. In addition, the change of the state can further generate other control information, for example, instead of the current user click, 'to select the menu. Option, or other = double ^ 'Please refer to Figure 5 and in contrast to step (6) of Figure 6 change H Ming f in an embodiment, according to the direction of the state of the front and rear information. The judgment is for example: η phase generation Control • When the direction state, from S1_S2, or S2—S3, or S3 shoulder or (10)i ......... is judged to be clockwise rotation, set the clockwise flag to i • When the direction is away from the counterclock flag The flag is set to 0 MS144S4—83, or Magic 1, or 82 8 8 200931318 ......... judged as counterclockwise rotation, set the inverse clock flag to i. The clock flag is set to 〇 "Do you want to rotate? And "Rotation Direction" can be used individually as a type of protection command. In addition to 'see Figure 5 and in contrast to Figure 7 - steps 701 to 710, in another embodiment of the invention, more instructions can be provided depending on the magnitude of the rotation, for example: The state is judged as clockwise rotation from SI_S2, or S2_S3, or S3sS4, or S4~S1 ........., clockwise count +1 inverse clock count 当 • when direction state is from S1 —S4, or S4—S3, or S3—S2, or S2—S1 ......... judged to be counterclockwise, and count the inverse clock count +1 clock count to 0 ♦ rich clock count value or inverse The clock count value reaches a preset value (for example, 4) .... emits a corresponding control command β. Thus, the present invention provides a greater number of clicks than a conventional click/double click touch method. The control command; and because there is no need to press the command input position (1) '- Fang Fang will not misunderstand him, and the other side does not need to place the pressure control mechanism inside the casing 11. The above advantages are more prominent in small electronic devices such as mobile phones. The present invention has been described above with respect to the preferred embodiments, and the above description is only for those skilled in the art to easily understand the contents of the present invention, and 9 200931318 is not used for the mosquitoes (4). It is possible to immediately consider various equivalent changes in the spirit of the present invention. Ο The first 2_ is used on the mobile phone as an example, but it can be applied to other small-band electronic devices or other large-sized ones. The method of generating an instruction based on a clockwise clock is not limited to an apparatus for generating an instruction by an application method, and may be used in other types of U input apparatuses. The optical element and sensing circuit 3G and processing circuit 4 shown are divided into two components', but the components can be separated. All changes and equivalents of the concept and spirit of the present invention are intended to be included in the scope of the present invention.
