US 2013/0155026 A1 · NEW KIND OF MULTI-TOUCH INPUT DEVICE

Abstract

A multi-touch method includes, in response to at least one finger of a user pointing toward a computer screen, recognizing an eye and at least one finger in an image frame taken by a camera; mapping a first coordinate of the recognized finger in the image frame to a second coordinate of the finger on the computer screen; mapping a third coordinate the recognized eye in the image frame to a fourth coordinate of the eye on the computer screen; determining whether the fourth coordinate is in the proximity of the second coordinate; in response to a positive decision, determining the second coordinate as a multi-touch point.
