When the mouse 1 changes from the normal placement state to the inverted state, the first switching signal is sent to the computer host 2, and the computer host is controlled. The mouse control mode is switched to the mouse handwriting input rhyme type: the machine 2 performs the handwriting function after receiving the mouse signal, and the mouse 1... the main switch is the strip system 3G2, the user can input the handwriting The cut light source enters the area for handwriting input. The mouse 1 detects the user's handwriting wheel and enters the handwriting wheel and transmits the handwriting input track information to the host computer through the transmission line. The computer host 2 converts the handwriting input track information into the handwritten wheel content of the handwriting, and the handwriting is handwritten. The input content is displayed on the display 3. When the mouse 1 changes from the flipped state to the normal state, the mouse 1 sends a second switching signal to the computer host 2, and the control computer host 2 is switched from the handwriting input control mode to the normal mouse control mode, that is, the computer host 2 After receiving the mouse transmission signal, the cursor movement and the left and right button functions are executed. At the same time, the light source of the mouse is switched to the normal mouse light source 301, so that the user can perform the cursor control of the ordinary mouse by the mouse 1 and the like. [Face] Please refer to Fig. 2' for the hardware frame of the multi-function mouse and system embodiment. 099122922 Form No. A0101 Page 7 / 19 pages 0992040403-0 201203024 [0022] In this embodiment, the multi-function mouse 1 further includes a state sensing unit 40 for sensing the placement state of the mouse and according to The change of the placement state sends a corresponding switching signal, an imaging unit 50, and a processing unit 60. The imaging unit 50 includes the emission source 30, a set of optical lenses 511, and an optical sensor 502. [0023] The computer host 2 includes a mode switching module 70, a mouse control module 80, and a handwriting input control module 90. The mouse control module 80 is used to perform the function of normal mouse input, and the handwriting input control module 90 is used to perform the function of inputting by the mouse hand. The mode switching module 70 is configured to receive the switching signal sent by the mouse 1 and execute the normal mouse input or activate the handwriting input control module 90 to perform the handwriting input function according to the corresponding mouse control module 80 corresponding to the received switching signal. [0024] In the embodiment, the state sensing unit 40 is a gravity sensor. When the state of the multi-function mouse 1 changes, the gravity sensor senses the change of the center of gravity of the mouse 1 to determine the placement. The state changes and a corresponding switching signal is generated. Wherein, when the multi-function mouse 1 is turned over by the normal placement state, the gravity sensor senses the inversion and issues a first switching signal. The processing unit receives the switching signal to activate the strip light source 302 and turns off the normal mouse light source 301, and the processing unit transmits the first switching signal to the mode switching module 70 of the computer host 2 via the transmission line, and the mode switching module 70 is The switching signal activates the handwriting input control module 90, and the computer host 2 enters the handwriting input control mode, and the user performs handwriting input in the area of the mouse 1 handwriting input unit. [0025] The imaging unit 50 is configured to acquire a user's handwritten input image. The light emitted by the strip light source 302 is partially illuminated by the optical lens to illuminate the transparent material at the bottom of the mouse 1 099122922 Form No. A0101 Page 8 / 19 pages 0992040403-0 201203024 Layer 201, a portion is reflected by the transparent material layer 201, and by a The group optical lens 501 is transmitted to the optical sensor 502 (microimager) for continuous imaging of the transparent material layer 201. When the user touches a point on the transparent material layer 201 by a finger or other object, a dark spot is formed at the point, and the optical sensor 502 can capture the image of the transparent material layer 201 with the dark spot. Therefore, when the user performs handwriting input on the transparent material, the optical sensor 502 captures the image of the transparent material layer 201 continuously, so that the movement trajectory of the user's handwriting input is recorded as a set of consecutive images of high-speed shooting 〇[0026 The processing unit 60 is connected to the optical sensor 502 to acquire a handwritten input image recorded by the imaging unit 50. The processing unit 60 derives the user's handwritten input movement trajectory by analyzing changes in the position of the feature points on the consecutive images. The processing unit 60 transmits the obtained signal including the movement track information to the computer host 2 through the transmission line. [0027] The handwriting input control module 90 in the computer host 2 receives the signal sent by the mouse processing unit 60 including the user's handwriting input movement tracking information, identifies the handwriting input movement track, and converts it into corresponding handwriting input content. ❹ And after each handwriting stage is completed, the handwritten content is compared and corrected, thereby obtaining handwritten input content, such as letters, characters, etc., to realize the handwriting input function of the mouse and display on the display 3. [0028] When the mouse 1 changes from the flipped state to the normal state, the gravity sensor senses the flip and sends a second switching signal, and the processing unit 60 activates the normal mouse light source after receiving the second switching signal. 3 01 and the strip light source 302 is turned off, and the processing unit transmits the second switching signal to the mode switching module 70 in the computer host 2 through the transmission line, and the mode switching module 70 starts the mouse control according to the second switching signal.

[0029] In the present embodiment, the transparent material 201 covered by the handwriting input unit is a transparent plastic, glass, or the like. [0030] In other embodiments, the state sensing unit 40 can be a pressure sensor disposed on the bottom of the mouse. When the mouse is in a normal state, the weight of the mouse itself will be A pressure is generated on the pressure sensor. When the mouse is turned over from the normal placement state, the pressure sensor does not sense the gravity of the mouse to generate the first switching signal, and when the mouse changes from the flipped state to the normal placed state, the pressure sensor senses the gravity of the mouse. A second switching signal is generated. In other embodiments, a specific button can also be set on the mouse to control the generation of the first switching signal and the second switching signal. 3 is a flow chart of an embodiment of the present invention, as shown in the figure: [0032] When the multi-function mouse wants to switch modes, it is first determined whether the mouse has a flip operation S301. [0033] If the mouse is turned over from the normal placement state, the state sensing unit 40 senses the flip and sends a first switching signal, and the processing unit 60 receives the first switching signal to turn on the strip light source 302 of the mouse. The normal mouse light source 301 is turned off, and the first switching signal is transmitted to the mode switching module 70 in the computer host 2, and the mode switching module 70 activates the handwriting input control module 90 (S302). The user is detected by the movement of a finger or other object on the transparent material layer 201. When the user moves on the transparent material layer by a finger or other object, the movement trajectory is recorded by the imaging unit 50 as a group of high 099122922 Form No. A0101 Page 10 / Total 19 Page 0992040403-0 201203024 Coordinated image remote processing unit for speed shooting 6〇 Acquire the handwritten input image recorded by the early 50, and obtain the user's handwriting input movement trajectory by the change of the position of the feature point on the fractal image (S3〇3). The moving track information is transmitted to the host computer 2 through the transmission line, and the handwriting input control module 90 of the computer host 2 receives the handwritten input moving track, destroys the βHai handwriting input moving track and converts it into corresponding handwritten input content. (S304). Finally, the recognized handwriting input content is displayed on the display (S305).
