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 som

Embodiment Construction

[0046] The concept of the present invention comes from careful observation and research, and it is found that the user's operation of a common mouse of a notebook computer has the following characteristics: when the mouse is moved substantially, the arm is used to move, and after reaching a general area quickly, the wrist and mouse are used to move the mouse. Use your fingers to make fine adjustments. This feature is very ergonomic, because the arms of the human body are much longer than the fingers and wrists, but the control accuracy is not so accurate, and the movement of fingers and wrists is much more accurate, although the moving distance is limited; and in the mouse movement During the process, there is a division of labor between the wrist and fingers. The fingers are mainly responsible for fine-tuning the front and back, while the wrist is responsible for the left-right movement and rotation with a certain arc, which is also the basic feature derived from ergonomics. ...

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...
