Abstract

PROBLEM TO BE SOLVED: To improve the recognition rate of key having the high frequency of use. SOLUTION: When a pen touch position on a monitor 15 is detected by an input position detecting part 11, it is discriminated by an area discriminating part 12 whether the pen touch position is located in a recognizable zone or a dead zone. When the recognizable zone is discriminated, the number of times of key use recognized by a recognizing part 13 is counted by a use time counting part 16. Each time a predetermined time interval passes, the number of times of use counted by the use time counting part 16 is sorted in descending order by a sorting part 17 and two high-order keys are selected. Next, the area of recognizing area of two keys is set larger than a default area as the prescribed area and the area of other keys is set as the default area. Afterwards, the keys consisting of a keyboard are switched to the area, which is set by an area setting part 18, and displayed on the monitor 15 by a display control part 14.
