Embodiment Construction

[0067] The specific implementation of the present application will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the application, but are not used to limit the scope of the application.

[0068] Those skilled in the art understand that in the embodiments of the present application, the size of the sequence number of the following steps does not mean the order of execution. The order of execution of each step should be determined by its function and internal logic, and it does not apply to this application. The implementation process of the embodiment constitutes any limitation.

[0069] In the course of research, the inventor found that when the user's finger presses an object and lifts it after pressing, it will cause the blood flow signal collected at the finger position to produce obvious waveform changes, and the waveform is pressed or lifted. The influence of the speed of intensity change. ...

Abstract

The invention provides a force value change speed information determination method and equipment, and relates to the field of wearable equipment. The method comprises the following steps of: in response to a fact that a pressing action is executed on an object by a finger of a user, obtaining blood flow information of the finger; determining a target waveform in the blood flow information, wherein amplitude values of points on the target waveform are gradually increased and are higher than a threshold value; and determining force value change speed information of the pressing action according to the target waveform. Through above technical scheme, the invention provides a method and equipment for determining force value change speed information according to the blood flow information; and the method and equipment can reuse blood flow sensors on the wearable equipment and are beneficial for improving the interaction ability of the wearable equipment.

Description

Technical field [0001] This application relates to the field of wearable devices, and in particular to a method and device for determining information about the speed change of force. Background technique [0002] With the popularization and development of electronic devices, current electronic devices are becoming more and more intelligent. Among them, the recognition of user actions by electronic devices is one of its intelligent development directions. [0003] Existing electronic devices generally recognize the user's motion force related information, such as pressing force value, through a touch screen, so as to realize information input and facilitate the interaction between the user and the device. [0004] In the field of wearable devices, due to its small interactive interface and weak interaction capabilities, it is difficult to directly apply some methods for detecting information related to motion intensity through a touch screen. Summary of the invention [0005] The pu...
