Detailed ways

The preferred embodiment of the present invention is illustrated by an optical mouse capable of measuring physiological signals. FIG. 1 is an exploded perspective view showing the appearance of this embodiment, which is mainly composed of a housing 1 and a printed circuit board 2 . The housing 1 is composed of a cover 11 and a base 12 . The cover 11 has buttons 111 , 112 , a roller 13 partially protruding from the cover 11 , and a groove 113 . The light sensor 4 is disposed in the groove 113 . In this example, the light sensor 4 is preferably a photodiode (Pholo Sensor).

The above-mentioned printed circuit board 2 mainly has electronic components such as an optical mouse light source 21 and a sensor chip 22 . In this example, the optical mouse light source 21 is preferably a light-emitting diode that emits red light; the sensor chip 22 is preferably an oxide semiconductor image sensor.

FIG. 2 shows a functional block diagram of the present invention, which mainly includes a control unit 61 , a signal processor (DSP) 62 , a light source adjustment unit 63 , a photosensitive unit 64 , and an input/output interface 65 . In this example, the input and output interface 65 is preferably a universal serial interface (USB).

The operation of this embodiment will be described in detail below. Please refer to FIG. 1 and FIG. 2. The control unit 61 is mainly composed of the buttons 111, 112, the scroll wheel 13, or the sensing chip 21. The control signals are sent to the computer device 5 through the input and output interface 65 to generate actions such as cursor displacement or command execution displayed on the computer device 5 . Wherein, the light signal received by the sensing chip 22 is sent by the optical mouse light source 21, the light signal will reach the desktop through the hole 121, and then reflect back to the hole 121, and then reach the sensing chip through the sensing hole 23 twenty two.

The photosensitive unit 64 described in this example mainly uses the photosensor 4 to receive the light signal from the indoor light source signal penetrating the human finger. When the user manipulates the optical mouse, the finger is placed in the ergonomic groove 113, and the indoor light signal will penetrate the finger (including the microvessels inside the finger) and reach the photosensor 4, and pass through the photosensitive unit 64. Signal processing (including signal high-pass or low-pass filtering processing and amplification processing) is sent to the signal processor 62 to obtain the brightness of the indoor light source and calculate the pulse rate of the user at that time.
