Information input device and method for portable electronic device

Abstract

The invention discloses an information input device of a portable electronic device, which comprises a touch unit, a touch input processing unit, a keyboard key and a keyboard controller; it also includes an input mode switching unit connected to the keyboard controller; the touch unit and the keyboard keys form a A stacked structure: the keyboard controller receives the signal of the input mode switching unit, and processes the input information from the keyboard keys and the touch input processing unit according to the signal. The invention also discloses an information input method of the portable electronic device.

Description

technical field [0001] The invention relates to a position input technology of a portable electronic device, in particular to an information input device and method of a portable electronic device. Background technique [0002] During the rapid development of computer technology, the invention of keyboard and mouse has brought a lot of convenience to people, and they have been fully applied, and the technology of keyboard and mouse itself has also changed 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 photoele...

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

[0015] Although touchpads are the most popular on notebook computers, in terms of handling, there are indeed some places that are not as good as ordinary mice. This is also a very important reason why many notebook computers randomly give a mouse during the sales process.

[0016] The poor controllability of the touchpad mainly comes from the following factors: First, the location problem. The touchpad is generally located below the keyboard, near the space bar, and the space bar is generally operated by the thumb. During operation, the thumb is easy to touch the touchpad, causing the position of the cursor to move, and because the touchpad is relatively sensitive, if you do not pay attention, it is easy to cause misoperation and input in the wrong position, which affects the efficiency of keyboard input; secondly It is not easy to operate with one hand, because the position between the buttons and the touchpad is not suitable for one-handed operation, and the usage habits are different from ordinary mice, so I want to use the touchpad to complete some more complicated cursor buttons The operation is more difficult, such as playing games, drawing, etc., is still not as convenient and flexible as a normal mouse; again, the positioning part is too far away from the keyboard, and the moving distance is relatively long when the keyboard and touchpad are frequently operated alternately, and every time it is used from When the trackpad is moved to the keyboard, the fingers need to be repositioned, such as finding the F and J keys with raised marks on the keyboard keys, so it is still very troublesome

[0017] In addition, the cooperation between the touchpad and the keyboard is not as good as that of the trackbar, and the volume arrangement is not as good as that of the trackstick. It will be more difficult to further reduce the size
