specific Embodiment 1

[0072] Such as figure 1 As shown, on the inner side of a cylindrical surface, there are 6 key positions of the same size and shape evenly distributed along the circumferential direction, represented by 0 to 5, and each key position is the inner area of ​​the cylindrical surface between two adjacent bus bars, It is effective when the pressure F≥F0 is received. Below the cylindrical surface, there is a plane connected with the cylindrical surface to form a bucket-shaped inner surface. The circular key R is located in the center of the plane, and it is a redial key. When the pressure F≥F0 and F<F1 is received, the key R is invalid; when the pressure F≥F1 is received, the key R is valid.

[0073] Two pairs of keys can be moved in one direction along a straight line in the plane, from one key to another without passing through any key of the keyboard.

[0074] An example of an action is as follows:

[0075] 1. To move from key 0 to key 1, one-way movement can be made along a str...

specific Embodiment 2

[0077] Such as figure 2 As shown, from the appearance, there are 4 circular keys of the same size in the plane, and the centers of the 3 circular keys are located on the 3 vertices of an equilateral triangle, and there is a circular key in the center of the regular triangle bit as the redial key bit. For each bond, when the pressure F≥F0 and F

[0078] An example of an action is as follows:

[0079] 1. To move from key 0 to key 1, one-way movement can be made along a straight line in the plane.

[0080] 2. To move from key position 0 to key position 4, one can move along a straight line in the plane and move in one direction along a straight line in space, or the pressure changes from light to heavy, and the shortest synthetic route is a straight line.

[0081]When entering two keys in the sam...

specific Embodiment 3

[0082] Such as image 3 As shown, from the appearance, there are 6 circular keys of the same size in the plane, and the centers of the 6 keys are located on the 6 vertices of a regular hexagon. For each key position, when the pressure F≥F0 and F

[0083] Every pair of keys can move from one key to another through an action without going through any key on the keyboard. An example of an action is as follows:

Abstract

The invention discloses a portable computer keyboard, the action of pressing and releasing a key position is used for inputting two key positions, so the portable computer keyboard can only use 12 key positions to replace the 121 keys of the previous keyboard of a PC machine and achieve the equivalent input speed.

Description

technical field [0001] The invention relates to a portable computer keyboard, which can be used for PCs, mobile phones, telephones, remote controllers and the like. Background technique [0002] All kinds of portable information devices require lightness and compactness, while the high-speed operation with ten fingers requires the keyboard to maintain a sufficient size, which creates a contradiction. The above-mentioned contradictions are more prominent in the case of information appliances (IA), personal digital assistants (PDA), electronic books (e-book), mobile phones and global positioning system (GPS) and other products being widely used. Touch screens and touch panels are suitable for querying information or controlling, but the voice operation method is not yet mature. Although the mobile phone keyboard only uses a dozen keys, it is difficult to achieve high-speed input. Can a better input method be found? Contents of the invention [0003] The present invention ov...
