The invention pertains to methods, which allow a keyboard to be compact, fast, comfortable and customizable. These methods are universally applicable, applied herein to three applications - PC keyboard, mobile phone keyboard, and one-hand typing keyboard. The PC keyboard invention has 44 keys, symmetrically laid out in two independent sections that allow the user to adjust the angle and distance between the hands for operating comfort. The invention is easier and faster to operate than the traditional QWERTY keyboard and incorporates features such as abbreviated typing. It is much smaller in size hence can be offered in different key sizes to accommodate different hands sizes. Besides supporting the QWERTY layout, an efficient alternative key layout named WHRL has been invented. The mobile keyboard and one-hand keyboard inventions can be applied to a wide range of applications such as portable devices, toys, educational tools, and industrial applications. |
