METHOD FOR DETERMINING NUMBER OF TOUCH

摘要

PURPOSE: A touch counting method is provided to determine the number of touches by sensing multi touch through analysis of a touch sensing signal. CONSTITUTION: A touch sensing signal is sensed by an infrared ray sensor module(S3). A touch sensing signal part is defined as a touch recognition signal. The touch sensing signal indicates touch. The touch sensing signal is analyzed. If threshold length of the touch sensing signal is located in threshold area, the touch sensing signal is reanalyzed. The touch sensing signal is recognized according to a reanalysis result.
