Method and arrangement for entering data in an electronic apparatus and an electronic apparatus |
摘要 |
The invention relates to a method and arrangement for creating a virtual keyboard for a terminal (800) used in a cellular network. The virtual keyboard is generated using an IR transceiver arrangement (12) in which a reflection from an obstacle (15) placed in the field of IR transmitters is registered by discrete IR receivers. The received reflection data are processed in a neural network arrangement (33). The purpose of the data processing is to find out the virtual key position/function that the received reflection data corresponds to. |
