Title: Method of identifying genuine input key by estimating user's intention of input
Inventor: NAM SUNG SIK
IPC: G06F3/02
Filed: 2007-10-23
Abstract: A method for distinguishing an input key estimating the input intention of a user for providing selective priority through simple operation is provided to distinguish the input key even in case that the signal strength about the target input key is obtained less than the critical value. A plurality of input signals showing the input of the user about a plurality of input keys is received(S310). The specific input signal is selected between a plurality of input signals and the specific input signal. The fixed offset value is in the intensity of the selected input signal. The signal strength value of the input key corresponding to the selected input signal is determined(S320). The intensity of the input signal which is not selected is determined as the signal strength value of the input key corresponding to the input signal(S330-S340). The size of the signal strength value of the determined plurality is compared.
