Acceleration sensing-based virtual air keyboard

Abstract

The invention discloses an acceleration sensing-based virtual air keyboard, relates to an information input device, and provides the acceleration sensing-based virtual air keyboard which not only can sense, analyze and compute finger movement loci of an operator, confirm key pressing actions of the operator and further identify the input intention of the operator to realize non-contact input without foundation, but also is convenient and flexible to use with silent keys, novelty and interesting and can improve the work efficiency and the life quality of the operator. The acceleration sensing-based virtual air keyboard is provided with a glove, key sensing modules, a central processing module, a terminal communication module and a power supply, wherein the key sensing modules are arranged on finger tips of the glove; the input port of the central processing module is connected with the output ends of the key sensing modules; the input port of the terminal communication module is connected with the output port of the central processing module; the output end of the terminal communication module is communicated with an external terminal; and the power supply is used for providing power for the key sensing modules, the central processing module and the terminal communication module and realizing power supply management.

Description

Virtual Air Keyboard Based on Acceleration Sensing technical field The invention relates to an information input device, in particular to a virtual air keyboard based on acceleration induction that enables an operator to control information input out of thin air. Background technique Existing keyboards supporting terminals such as computers mostly continue to use the layout of the original English typewriter plane keyboard, and each key position is fixedly arranged in a plane in row dislocation. This type of keyboard has the following disadvantages when in use: 1) Due to the fixed layout of the existing keyboard keys, there are strict restrictions on the operation method of the operator, which is not humanized enough. Therefore, the operator cannot change the posture of the hand during operation, and it is easy to cause wrist stiffness after long-term use. 2) Since all keys of the existing keyboard are arranged on the same plane, the keyboard is bulky and inconvenient t...

AI Technical Summary

Problems solved by technology

1) Due to the fixed layout of the existing keyboard keys, there are strict restrictions on the operation method of the operator, which is not humanized enough. Therefore, the operator cannot change the posture of the hand during operation, and it is easy to cause rigidity of the wrist after long-term use

2) Since all keys of the existing keyboard are laid out on the same plane, the keyboard is bulky and inconvenient to carry

3) Since the existing keyboards are generally of a mechanical structure, it is impossible to achieve silent input, so it is not suitable for places that require a quiet environment

4) Since the existing keyboard needs a hard desktop as a support, the operator cannot input information while standing, lying down, or walking, and typing on the desktop keyboard for a long time can easily induce occupational diseases such as cervical spondylosis and osteoarthritis

Although the operator can press the keys with both hands and the posture of the hands can change continuously when using it, this kind of keyboard cannot realize silent input, nor can it perform normal operation when there is no light

Obviously, the above-mentioned improved technology or products proposed for the keyboard cannot completely overcome the shortcomings of the existing keyboard, and the operation tends to be complicated, not humanized enough, and also reduces the quality of life.
