Typically, the devices used for cursor control include keyboards, mice, trackballs, and touch pads. Cursor control with a mouse is much more convenient than using a keyboard because the keyboard requires a row-row or-column-column to move the cursor. 'However, sometimes in some applications the slippery efficiency is not good. For example, when a user is typing on a keyboard, it is inconvenient to use the mouse to move the cursor away from the keyboard from time to time to move the cursor more quickly. In addition, if the user is playing a video game, he may feel tired if he needs to click the mouse button at high speed. The vertical ball is a mechanical slipper that is installed in the notebook computer. It requires less hand movement and higher space efficiency than a mouse. However, the vertical ball is prone to wear and dust. In addition, its accuracy does not meet the requirements in some applications. Touch pads are currently the most widely used cursor control device for notebook computers. It includes a pressure sensitive plate and at least one button. The responsive board is responsive to the movement of the finger. When the finger touches the touch pad, the responsive plate responds to the movement of the finger and outputs a control signal for controlling the movement of the vernier. With trackball two:, the touchpad is less prone to wear and tear, and can be moved at a much faster speed 5061-9215-PF 5 200817983 ... has moved the cursor, as well as with higher precision. However, touch 塾 not :::. : In some applications, such as video games, it is possible to: 月 疋 疋 。 。 °. Some users have to move a few times before they can move to the desired location. Therefore, it is advantageous to have a cursor position that can be quickly and accurately positioned. And the operation of the device is required to be convenient and intuitive. It is also required to be durable and reliable. In addition, 'low cost equipment is advantageous.

In the case of cobalt, the user can hold the sensing module 8 and point it to the positioning plate 85. As described above, the positioning plate 85 is superimposed on the screen 9 of the electronic device, so the sensing module 8 can be used at a close distance from the screen 9. As a result, the user/and a heavy-duty and portable module 8 can directly control the cursor on the screen 9 of the electronic device as he needs. When the user directs the sensing module 8 to a particular position on the positioning plate 85, the illumination unit 81 in the sensing module 8 produces an incident beam 83 to illuminate an area of the positioning plate 85. The positioning plate 85 reflects the incident beam 83, thereby producing a reflected beam 84 with pattern information of the illuminated region. The optical sensing unit 82 receives the reflected beam 84 and generates a beam sensing signal based on the pattern information.

In accordance with a preferred embodiment of the present invention, a one-to-one correspondence between the pattern of the positioning plate 85 and the coordinate system on the screen 9 is preset in the control unit 88. Control unit 88 receives the beam sensing signal from optical sensing unit 82 and produces a position signal for identifying the coordinates of the illuminated region (i.e., the coordinates of the incident point position of incident beam 83). Control unit 88 also generates a cursor control signal based on the position h number to control the motion of the cursor. Figure 2 shows a flow diagram of a cursor control process in accordance with one embodiment of the present invention.

For example, the incident beam can be generated by a lighting unit (e.g., illumination unit 81 shown in Figure 1). 5061-9215-PF 9 200817983 ' In step 1〇2, the positioning plate reflects the incident beam, thereby producing a reflected beam with pattern information of the illuminated area on the positioning plate. In the step, the pattern information in the reflected beam is used to generate a beam sensing signal. For example, an optical sensing device (e.g., optical sensing unit 82 as shown) can generate a beam sensing signal. In step 104, according to the pattern of the positioning board and the coordinate system between the electronic device screen (the screen 9 of the electronic device shown in FIG. 1), the ί relationship is recognized when the light beam sensing signal is received. The position of the incident point of the incident beam: coordinates, resulting in a position signal. In a final step 105, a cursor control signal is generated based on the position signal to control the cursor on the screen of the electronic device. For example, the cursor is controlled by the host. Figure 3 is a diagram of a cursor control device 71 in accordance with another embodiment of the present invention. As shown in FIG. 2, the cursor control device 71G includes a positioning plate 785, a sensing module 78, and a control unit 788. The positioning plate is also referred to as a positioning piece. The sensing module 78 is also referred to as a coordinate sensing device, a aiming device, or a pointing device.

Motion in λ + * aa, $ β. Control unit 788 generates a cursor control signal based on the vector. When the user wishes to position the cursor to a certain position on the screen, he can point the sensing group 78 to the current position of the cursor and then move the cursor to the new position they desire through the sensing module. The user can also sense the board group 78# to any position on the screen 9, and then move it on the positioning board. Control unit 788 controls the cursor to move on positioning plate 785 along a track that is parallel to the motion of incident beam 783. 4 is a flow chart showing a cursor control process in accordance with another embodiment of the present invention. In a first step 301, the incident beam illuminates a positioning plate (e.g., the clamping plate 785 shown in Figure 3). For example, the incident beam can be transmitted by a lighting unit, such as illumination unit 781 shown in FIG. In step 302, the locating plate reflects the incident beam to produce a reflected beam. In step 303, a data signal is generated according to the reflected beam. The data signal includes information about the pattern on the illuminated area of the positioning plate. For example, an optical sensing device (e.g., optical sensing unit 782 shown in Figure 3) 5061-9215-PF 13 200817983 can receive a reflected beam and generate a data signal. In step 304, the bedding signal of time . 0 is stored as a reference material. In step 305, the time/loss is stored. Sample information. The data signal is taken in step 306, and the sampled capitalization, the Shi, the jitter and the reference data are compared to generate the time t on the positioning plate. When the area is illuminated, the correlation function between the 疋 position and the engraved area of td + Δt is observed. ...,, in step 307, the root slag 4f generates a vector for describing the motion of the illuminated area on the locating plate based on the generated correlation function. In a final step 308, the thief a thief generates a vernier control signal to move the cursor over the screen of the electronic device. Compared with § pre-cursor control devices such as expensive finger-finger: eternal, pad, etc., this 'X Ming Hao is reducing costs. In fgj, the electronic device is user-friendly due to the cursor control device. For example, the present cursor control apparatus and method can be widely applied to electronic games 'because the present invention is compatible with fast moving, fast and precise determination, and can use cursor control devices and make the cursors easy and free according to their requirements. Positioning. In operation, players can use it, just like moving the cursor over the screen directly through their own hands. In addition, electronic devices such as video game machines have a longer life because users do not need to directly touch the screen.
