Wearable virtual keyboard and its implementation method

Abstract

The invention discloses a wearable virtual keyboard and a method for realizing the same. The wearable virtual keyboard includes finger cots or finger stickers and a data processing output device. Keyboard information, finger cots or finger stickers are equipped with a chip that recognizes the fingerprint information of the finger that is tapped, senses the contact area information between the finger and the tapped surface and sends it to the data processing output device according to the tapping action; the data processing output device and the finger Cover or finger sticker connection, receive and analyze the finger fingerprint information and contact area information sent by the chip, the data processing output device includes a data processing device and an output display device, the data processing device generates finger input information according to the finger fingerprint information and contact area information and Send to the output display device, and the output display device outputs and displays the finger input information. The wearable virtual keyboard of the present invention occupies a small space and is convenient to carry around, both hands can move freely, and the accuracy rate is high.

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
