Data input device |
摘要 |
A data entry system includes a number of sensors (27) behind a smooth surface (26). A pointer (34), such as a finger, traces out characters on the surface (26). An interpreter (30) matches the characters traced with predetermined patterns and outputs a corresponding character. The data entry system is suitable for use in small hand-held devices such as mobile telephones. It is suitable for entering Chinese characters.
