Abstract: Touch detection includes obtaining image data for a finger and a target surface, and determining a touch region in the image data on which the fingertip makes contact with the target surface. A pointing direction of the finger in the image data is determined, and a target region is estimated on the target surface based on the touch region and the pointing direction, wherein the touch region comprises a portion of the target surface that extends from the touch region in a direction of the pointing direction.
