Touchpad, touch input method and touch input system integrating track input and key input

Abstract

The invention belongs to the technical field of electronic information, and relates to a touch input method, a touch input device and a touch input system integrating track input and key input. A touchpad is characterized in that track input areas and independent blocks for key input and having the inclusion relation with the track input areas are set up in each touchpad sensing area, and by means of non-simultaneous switching, one touchpad can complete track input to realize convenient operation on a graphic interface and can complete key input to realize key information (character key information, control key information and the like) input. When the method is applied to an electronic product, less physical space can be occupied by the input device so that the product can be designed to be lighter and thinner, and the input device can also occupy less superficial area of the electronic product, so that the product can be designed to be smaller.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to an electronic input device, in particular to an input system based on a touch-type signal input device. Background technique [0002] As a signal input device, the keyboard is widely used in electronic equipment. It includes a plurality of mutually independent keys. Each key realizes the short-term conduction of the corresponding key circuit through contact bonding to complete the input of the corresponding key information. Such as numbers, characters, control commands, etc. [0003] With the advent of the window operating system, the traditional keyboard needs to realize the operation of the complex interface through complex combination input or sequential input under the complex definition. Obviously, the traditional key-type input device is not enough for the operation of the complex interface. Therefore, a kind of displacement signal input device-mouse arises at...

Problems solved by technology

[0005] However, although the introduction of the touch panel will bring convenience in operation, it will inevitably lead to an increase in the size of the electronic device, which is not conducive to the miniaturization of the device, and at the same time, it will also increase the cost of the device.

If the device also has multiple buttons, sometimes there is not enough space to accommodate both the touchpad and the buttons. At this time, the size of the device must be further increased, otherwise it will only be at the expense of some functions or convenience of operation.
