  • Publication number: 20160034069
    Abstract: An information processing apparatus detects contact of a finger with a capacitive panel. The information processing apparatus, when the contact of the finger is detected, measures a midpoint at an equal distance from either end of a contact region where the finger is in contact with the capacitive panel, and measures a centroid of an area of the contact region. The information processing apparatus executes operation depending on a distance between the measured midpoint of the contact region and the measured centroid of the area of the contact region.
