Non-key keyboard input system and input method based on wireless sensor network technology

Abstract

The invention provides a keyless keyboard input system based on the wireless sensor network technique and an input method thereof. The keyless keyboard input system includes a terminal processing system and a keyless keyboard, wherein the keyless keyboard is composed of a plurality of sensor nodes, and the sensor nodes respectively located on finger joints of a palm are capable of describing hand contour and position relation among the joints of the hand. During typewriting, finger actions trigger the sensor nodes to detect different information, and the different information is recognized as identification features for carrying out the identification process of the keyless keyboard, then the identification features are transmitted to the terminal processing system through wireless communication, the terminal processing system processes the transmitted signal data, and then mode identification is carried out according to pre-stored table information matching with finger curvature, thereby finishing the text input process based on the finger curvature. With the input system, huge space occupied by the keyboard is saved during development of digital products, and the products are quite small in structure and bring great convenience for users.

Description

Technical field [0001] The invention relates to a keyless keyboard input system and input method based on wireless sensor network technology that combines wireless sensor technology and acoustic communication technology. Background technique [0002] At present, the keyboards on the market are wired, especially the keyboards on mobile phones, PDAs, etc., either use numeric keys instead of keyboards (usually the keyboard of mobile phones) or make the keyboard very small (for example, a full set of keyboards on PDAs). ). It is difficult to say that such a handheld computer is a computer in the true sense, because if you want to do document processing and other tasks, the keyboard greatly affects the speed of people's operations. [0003] Wireless sensor technology is a large-scale self-organizing network, through the correlation between network nodes, collaborative work to complete tasks. Currently, the positioning technology and synchronization technology in wireless sensor networ...
