Wearable virtual keyboard and implementation method thereof

Abstract

The invention discloses a wearable virtual keyboard and an implementation method thereof. The wearable virtual keyboard comprises fingerstalls or finger stickers and data processing output equipment, wherein the fingerstalls or finger stickers are worn on fingers of a user and correspond to fingerprint information and initialization keyboard information respectively; the fingerstalls or the finger stickers are provided with chips for recognizing the fingerprint information of click, sensing contact area information of the fingers and clicking surfaces and transmitting the information to the data processing output equipment according to clicking actions; the data processing output equipment is connected with the fingerstalls or the finger stickers for receiving and analyzing the fingerprint information and the contact area information transmitted by the chips; the data processing output equipment comprises a data processing device and an output display device; the data processing device is used for generating finger input information according to the fingerprint information and the contact area information and transmitting the information to the output display device; the output display device is used for outputting and displaying the finger input information. The wearable virtual keyboard has the characteristics of small space occupation, convenience in carrying, capability of realizing free movement of both hands and high accuracy.

Description

technical field [0001] The invention relates to a multimedia device, in particular to a virtual keyboard and its realization method. Background technique [0002] The current mainstream physical keyboards are bulky, bulky and inconvenient to carry around. At the same time, both hands must be placed on the keyboard to input, which is not suitable for special occasions. The existing virtual keyboards require additional equipment to provide cameras or lasers to realize the keyboard. function, but the accuracy is not high. The wearable virtual keyboards and scanning virtual keyboards that have been implemented on the market include laser virtual keyboards, data gloves, video-based gesture recognition virtual keyboards, bionic surface electromyographic signal-based virtual keyboards, and fluid concept keyboards LiquidKeyboard. [0003] The laser virtual keyboard must project a full-size computer keyboard on a desktop, which takes up a lot of space. At the same time, both hands m...

AI Technical Summary

Problems solved by technology

For video-based gesture recognition smart devices, users must place their hands within the scanning range of the video device, which takes up a lot of space, and the accuracy is not high, and the hands cannot move freely.

For smart devices that recognize gestures based on surface electromyography signals, when the user taps the input, the fluctuation of the finger's swing up and down is not very large, so the accuracy of the input data will be relatively low, and both hands must be placed on the same plane on, the hands cannot move freely
