Embodiment approach

[0052] An embodiment of the physiological detection device of the present invention is described below, but the present invention is not limited thereto; Saturation meter, and because the detection method of the blood oxygen saturation meter is known, so it will not be repeated here. It must be noted that the following description is used to cite an implementation of the physiological detection device 1 in the embodiment of the present invention to detect the current physiological information and finger displacement. When the physiological detection device 1 is used to detect the finger track , the motion vector between two sampling points can be used to calculate trajectory features.

[0053] refer to Figure 7A As shown, it shows an application example of the physiological detection device 1 according to the embodiment of the present invention, which is shown here as an optical finger mouse, for example. The physiological detection device 1 can be used to detect the displa...

other Embodiment approach

[0062] In other embodiments, the physiological detection device 1 can also use two image sensors to detect light of two different wavelengths, one of the image sensors or two image sensors can be equipped with a bandpass filter (bandpass filter) to Select the spectrum you want to receive.

[0063] sampling mechanism

[0064] The physiological detection device 1 of the present invention includes two light sources and performs two functions at the same time; wherein, the detection function of displacement and contact state is not limited to use image frames corresponding to specific wavelengths, and the detection function of physiological information must correspond to images of different wavelengths. Image frames are counted separately. Firstly, the sampling mechanism of the image frame in the present invention will be described below.

[0065] In one embodiment, the light source control unit 16 controls the first light source 111 and the second light source 112 to emit light...

Abstract

A physiological detection device comprises a finger detection unit, a storage unit and a processing unit. The finger detection unit is used for detecting a current track drawn by a current user and current physiological information of the current user. The storage unit is used for storing track features of preset tracks which are drawn by a plurality of users on the finger detection unit for preset time or for a preset number of times and correspond to the users respectively in advance. The processing unit is used for analyzing the current track and recognizing the current user according to the track features stored by the storage unit. The invention further provides a physiological detection method and a user recognition method.

Description

technical field [0001] The invention relates to a detection system, in particular to a physiological detection device capable of automatically identifying a user's identity, a physiological detection method and a user identification method used therein. Background technique [0002] It is known that the pulse oximeter uses a non-invasive method to detect the blood oxygen concentration and pulse rate of the user, which can generate red light beams (wavelength of about 660 nanometers) and infrared light beams (wavelength of about 910 nanometers) ) to penetrate the part to be measured, and use the characteristics of different absorption rates of oxyhemoglobin and deoxyhemoglobin (Deoxyheamo-globin) for specific spectra to detect changes in the light intensity of the transmitted light, for example, refer to US Patent No. No. 7,072,701, titled Method for spectro-photometric blood oxygenation monitoring. After detecting the light intensity changes of the two wavelengths of transm...
