| 摘要 |
The invention relates to a keyboard arrangement and a method for detecting an input character. In particular the invention relates to a method and arrangement for reducing the number of keys in a QWERTY-keyboard (20) or the like. One idea of the invention is to provide keys (210) with several characters and to provide alternative ways to press the key for entering a selected one of the alternative characters. The keys are preferably triangular or have three arms, and one of three characters can be selected by pressing the corresponding corner/arm of the key. The keyboard may preferably be formed of interlaced rows of keys. Linguistic disambiguation is advantageously used in addition to said mechanical disambiguation. The invention is well suited for mobile station keyboards.
