Information processing apparatus for recognizing multi-touch operation by which object is rotated
Abstract:
An information processing apparatus includes a display section, a touch count determining section, a rotation angle detector, a rotation angle determining section, and an image processing section. The display section displays an object. The touch count determining section determines a touch count on the display section. The touch count is a number of touch points on the display section. The rotation angle detector detects a rotation angle of a touch action including multiple touch points on the display section as a rotation specification angle. The rotation angle determining section determines a rotation performance angle by which the object is rotated based on the rotation specification angle and the touch count. The image processing section rotates the object by the rotation performance angle.
