Problems solved by technology

[0007] However, since the blood oxygen saturation meter detects the intensity change of the transmitted light, it will detect different light intensity signals with different parts to be tested; in addition, when the known part of the blood oxygen saturation meter detects When moving, chaotic waveforms with violent changes are detected and physiological characteristics cannot be calculated correctly, so it is not suitable for portable electronic devices

Embodiment Construction

[0038] In order to make the above and other objects, features, and advantages of the present invention more apparent, a detailed description will be given below with reference to the accompanying drawings. In the description of the present invention, the same components are denoted by the same symbols, and will be described here first.

[0039] Please refer to Figure 2A , which shows a schematic diagram of an optical finger mouse 1 according to an embodiment of the present invention. The optical finger mouse 1 is used to detect the displacement and contact state of the user's finger 9 relative to the optical finger mouse 1 , as well as the user's physiological characteristics, such as blood oxygen concentration and pulse rate. Generally speaking, the optical finger mouse 1 starts to calculate the displacement and the physiological characteristics when the contact state is determined to be a contact state.

[0040]The optical finger mouse 1 includes two light sources 111 and...

Abstract

The invention relates to an optical finger mouse which comprises two light sources, an image sensor and a processing unit, wherein the two light sources are used for emitting light with different wavelengths, so as to illuminate the surfaces of fingers; the image sensor is used for receiving the reflected light from the surfaces of the fingers, so as to generate a plurality of image frames; and the processing unit is used for detecting the displacement and contact state of the surfaces of the fingers and the physiological features of a user in accordance with the image frames. The invention further provides an electronic device.

Description

technical field [0001] The invention relates to a man-machine interface device, in particular to an optical finger mouse and a physiological feature detection device which can simultaneously detect user's physiological features, finger displacement and contact state. 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, thereby judging 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 the portable electronic device also has the function of detecting the user's physiological characteristics and giving a warning when ne...
