<p>On a touchpad, an input instruction that matches the operation that a user has intended can be performed so as to improve the operability. A contact distance calculating section (31) calculates a contact distance (D) of the vertical direction of a contact area, and a center coordinate calculating section (32) calculates a center coordinate (y) of the contact area on the basis of the contact information associated with a touchpad (16), which is detected by a detection section (17). Furthermore, a compensation coordinate calculating section (33) calculates a compensation volume (D/N) using the contact distance (D) and a predetermined compensation parameter (N). A determination section (34) determines whether or not there is a travel of the contact area, and a distance-travelled calculating section (35) calculates the distance travelled by a contact point using a compensation coordinate (Y = y + D/N) or the center coordinate (y) according to the result of the determination. Here, the distance travelled is calculated on the basis of the compensation coordinate during the travel of the contact area, and the distance travelled is calculated on the basis of the center coordinate during the stop, leaving, and contact start of the contact area.</p> |
