Abstract
A device for providing a touch-based user interface is disclosed. The device comprises a screen, a camera, and a processor. The camera images a reflection of the screen by a cornea of a user of the device. The processor displays at least one user-interface element on the screen, detects that a finger of a hand touches or is about to touch the screen, estimates a trajectory of the finger, and determines an intended location of touch of the finger on the screen. The trajectory of the finger is estimated by analyzing a sequence of images of the reflection. The intended location of touch is determined based on the estimated trajectory of the finger.
