Abstract

A mouse capable of detecting physiological signal and detecting environmental luminance is disclosed, which has a shell and a base. A recess is defined in the shell to hold a user'"'"'s finger. A photo sensor is provided between the wall of the recess and the finger for detecting the environmental photo signal that penetrates through the finger. The photo sensor sends the detected photo signal to a computer via an input/output interface, so that the computer can determine and display the user'"'"'s physiological state.

Claims

1. A mouse capable of detecting physiological signal and environmental luminance, comprising:

a housing having a base and a shell fixed on the base, the shell having plural buttons, and a recess for receiving a human finger, the recess having a first photo sensor for detecting signal emitted from a light source; and

a printed circuit board for processing control signal generated by the plural buttons and receiving photo signal received by the first photo sensor, and sending the signals to a computer connected with the mouse via an input/output interface, such that the computer determines and displays human physiological state and based on the photo signals.

2. The mouse as claimed in claim 1, wherein the finger is placed on the first photo sensor.

3. The mouse as claimed in claim 2, wherein the light source is an environmental light source, and the photo signal generated by the environmental light source penetrates the finger to be received by the first photo sensor and sent to the computer.

4. The mouse as claimed in claim 1, wherein the printed circuit board has a digital signal processor for processing the photo signal received by the first photo sensor and sending the processed result to the computer by the input/output interface.

5. The mouse as claimed in claim 4, wherein the digital signal processor adjusts a DC level of the first photo sensor and an AC gain of the photo signal based on the photo signal received by the first photo sensor.

6. The mouse as claimed in claim 1, wherein the photo signal is transformed into human pulses for being displayed.

7. The mouse as claimed in claim 1, wherein the input/output interface is a universal serial bus interface.

8. The mouse as claimed in claim 1, which uses a standard mouse interface to move the cursor on the computer monitor, and the standard mouse has at least one control button and windows scroll function.
