Problems solved by technology

[0007] However, since the blood oxygen saturation meter detects the light intensity change of the penetrating light, it will detect different light intensity signals with different parts to be tested; in addition, when the part to be tested detected by the blood oxygen saturation meter moves , it will detect violently changing chaotic waveforms and cannot correctly calculate physiological information, so it is not suitable for electronic devices that operate on the move

Abstract

A keyboard module comprises a plurality of keyboard keys, an optic finger mouse and a transmission interface. The keyboard keys are used for triggering digital signals. The optic finger mouse is used for detecting physiological features and displacement. The transmission interface is used for transmitting the digital signals, the physiological features and the displacement to a display device. Further provided is a display system.

Description

technical field [0001] The present invention relates to a man-machine interface system, in particular to a keyboard module and a display system with a user's physiological feature detection function. Background technique [0002] An optical finger mouse (OFM) is generally suitable for matching with other electronic devices due to its small size. The known optical finger mouse is used to detect the light intensity change of the reflected light on the surface of the user's finger, so as to determine the contact state of the finger and the displacement of the finger relative to the touch surface. However, with the development of industrialization, users spend more and more time using various electronic devices, even exceeding physical load without realizing it. However, general electronic devices cannot detect the physiological condition of the user at that time. [0003] It is known that the pulse oximeter (pulseoximeter) uses a non-invasive method to detect the blood oxygen...
