AI Technical Summary

Problems solved by technology

When the keycap width shrinks to 15 mm, it is almost impossible for adults to use normally
The width of UMPC can only allow keycaps of 15 to 17 mm, which makes it very inconvenient to use
Some UMPCs simply abandon the integrated keyboard and use a touch screen instead, but the touch screen often limits the user's input speed
Some UMPCs use external portable keyboards, but external keyboards will affect the portability of UMPCs

Embodiment approach 1

[0034] This embodiment is a keyboard with only 42 keys, such as figure 2 shown. Except for 60, 63, 67, and 68, the rest of the keys are all standard size keycaps of 19mm. The keycap 63 has a width of 29 mm. The overall width of the entire keyboard is 219mm. The area marked black on the upper left of the keyboard has no keys.

[0035] This keyboard has seven working modes, among which mode 0 is the default working mode, and other modes are escape modes. Key 50 is a mode switching key, and different times of knocking on it can make the keyboard be in different working modes. In different working modes, the 29 keys 10-38 have different meanings. As shown in the table below:

[0036]

[0037]

[0038] In line with these meanings, several marks are drawn on each keycap, such as image 3shown. These markers are drawn in different colors to distinguish their meanings in different modes. At the same time, there are indicators of different colors on this keyboard, which ...

Embodiment approach 2

[0061] This embodiment is the same as Embodiment 1, except:

[0062] In various escape modes, the meanings of the 29 keys 10-38 are not specified at all, but depend on the user to set them through a certain configuration method.

Embodiment approach 3

[0064] This embodiment is the same as Embodiment 2, except:

[0065] The meanings of the 10 keys 60, 61, 62, 63, 64, 65, 66, 69, 51, and 52 are the same as those in Embodiment 1 in the default mode. However, in various escape modes, its meaning is not specified at all, but depends on the user to set it through some configuration method.

Abstract

The invention relates to data input equipment, in particular to a keyboard used as electronic computer input equipment. The invention relates to the industrial design of keyboards, an embedded controller and embedded software which are built in the keyboards, keyboard interface control circuits and the drive programs of computer hosts, operation systems or internal parts of an application program for processing keystroke information. In the invention, the spacebar on conventional keyboards is divided into a left part and a right part which are respectively controlled by the left thumb and the right thumb. The keyboard comprises a plurality of working modes and can switch the modes by the special move sequences of the two thumbs, namely, the respective knocking of the right and the left spacebars by the thumbs still means the spacebar, and the mode switching possibly exists when the time of the knocking of the spacebars approaches.

Description

technical field [0001] The invention relates to a data input device, especially a keyboard used as an electronic computer input device. The invention relates to the industrial design of the keyboard, the built-in embedded controller of the keyboard and its embedded software, the keyboard interface control circuit of the host computer and its driver, the part of the operating system or the application program for processing key information. Background technique [0002] For modern electronic digital processing devices—such as personal computers, PDAs or mobile phones, etc.—the input devices—such as keyboards and mice—convert user actions into digital signals and send them to devices such as computer hosts. From the user's tap action to the application's response on the screen, there are many steps to process. [0003] Take the PS / 2 keyboard as an example. The most original digital signal directly triggered by the user's action is often expressed as the level change of the i...
