Problems solved by technology

[0007] However, because the blood oxygen saturation meter detects the intensity change of the penetrating light, it will detect different light intensity signals with different parts to be tested; When moving, it will detect violently changing chaotic waveforms, which cannot be used to correctly calculate physiological characteristics, so it is not suitable for portable electronic devices

Abstract

The invention discloses a mouse control module which comprises two light sources, an imaging sensor, a processing unit and a communication protocol unit. The two light sources emit light with different wavelengths to illuminate a finger surface. The imaging sensor receives reflected light from the finger surface to generate a plurality of image drawing frames. The processing unit tests displacement of the finger surface and physiological characteristics of a user according to the image drawing frames. The communication protocol unit is used for encoding and / or sorting the displacement and the physiological characteristics to generate finger information and physiological information. The invention further provides an optical finger mouse.

Description

technical field [0001] The present invention relates to a human-machine interface device, in particular to a mouse control module that can simultaneously detect the user's physiological characteristics, finger displacement and contact state, and output coded, sorted and / or compressed finger information and physiological information and optical finger mouse. Background technique [0002] An optical finger mouse (OFM) is generally suitable for portable electronic devices due to its small size. The optical finger mouse can be used to detect the light intensity change of the reflected light on the surface of the user's finger, so as to judge the contact state of the finger and the displacement of the finger relative to the touch surface. However, with the development of industrialization, the time for users to use portable electronic devices is gradually increasing, even exceeding the physical load without realizing it. Therefore, if a portable electronic device also has the f...
