Touch control type information input device and method

Abstract

The disclosed device comprises: a user input unit to sense touch-control action of user's hand and produce opposite electric signal, a position information processor to detect and convert former signal into the touch-control position signal of user's operation unit, an interface unit to output converted position signal and user operation signal, a mouse function switch unit to distinguish former signals into an absolute / relative position signal to output mouse position moving information and generate virtual mouse function partition respectively.

Description

technical field [0001] The invention relates to a position input technology of a portable electronic device, in particular to a touch-type information input device and method. Background technique [0002] The invention of keyboard and mouse brings a lot of conveniences to people, is fully applied in the rapid development process of computer technology, and the technology of keyboard and mouse itself also changes thereupon. For the earliest keyboards derived from mechanical English alphabet typewriters, although there are not many changes in their basic layout and principles, for example, the main principle is XY array scanning, or mechanical contact or capacitive sensing, but in Great changes have taken place in terms of volume, usability, lifespan, lightweight, and cost. For the mouse that originated from the XY-axis image input device, from the initial X / Y-axis mechanical mouse to the photoelectric reflective mouse, the photoelectric encoding mechanical wheel rotating mo...

Problems solved by technology

But there are some defects in these existing technologies: on the one hand, it is different from existing keyboards and mouse usage habits, so it is difficult for users to accept; on the other hand, traditional mouse needs a relatively flat piece of plane to allow the mouse to move on it , so there are many restrictions when working in a mobile office. For example, when waiting for a plane at the airport, passengers in the general airport are not equipped with a small platform on the waiting seat, which greatly affects the application of scrolling and moving mouse positioning devices; in addition, keyboard and mouse To be connected together, a wired connection with the host is still required. If all of them are wireless, the cost will be relatively high

[0018] But there are some defects in the touchpad of this prior art: these positions that provide extended functions are relatively fixed, once set, just can't closely follow the movement of the palm with the movement of the main body of the mouse like a common mouse, causing fingers Inconvenient to operate

But the technology still doesn't solve the problem of how to make trackpads as easy to use as mice

The technology of time calculation is adopted, which involves complex calculations, which affects the reaction speed and is costly. Although it provides many ways to improve efficiency, it is still inferior to ordinary mice, which makes the application of touchpads Subject to certain restrictions, such as professionals, generally choose a photoelectric mouse as the input device for the cursor position
