A wearable device for measuring the opening angle between fingers

Abstract

The invention discloses a wearable interfinger opening angle measuring device, which comprises four finger cuffs arranged in sequence, spring pieces are arranged on the adjacent side walls of the finger cuffs, and each spring piece is provided with a resistance strain gauge , and the resistance strain gauges on the adjacent spring sheets are oppositely arranged, and the adjacent spring sheets are connected by a thrust bearing, and the thrust bearing includes a seat ring I, a shaft ring and a seat ring II sequentially connected by rivets, and the adjacent The spring pieces rotate relative to each other with the rivet as the axis, and the adjacent spring pieces can be opened at an angle; the invention has low cost, and the inter-finger angle measurement can be realized only by the spring piece, the resistance strain gauge and the thrust bearing.

Description

technical field [0001] The invention belongs to the technical field of gesture measurement, in particular to a wearable device for measuring the opening angle between fingers. Background technique [0002] Today, motion capture, virtual reality, teleoperation, gesture recognition, etc., as several ways of human-computer interaction, have gradually penetrated into various fields such as animation, medical treatment, education, and games. Taking gesture recognition as an example, some devices that can realize sign language recognition functions, such as data gloves, can be worn on the hands of deaf-mute people, and the gestures made by deaf-mute people can be recognized and finally converted into voice signals, so that such groups can reduce Small communication barriers, to achieve the effect of communicating freely with ordinary people. However, some existing commercialized data gloves such as 5DT and CyberGlove can only measure the bending angle of the finger's own joints. ...

AI Technical Summary

Problems solved by technology

However, some existing commercialized data gloves such as 5DT and CyberGlove can only measure the bending angle of the finger's own joints. Due to the lack of measurement of the opening angle between the fingers, the information related to finger activities is less, and more diverse The ability to recognize gestures is still insufficient
