Device and method for determining eye movements by tactile interface
First Claim
1. An apparatus for determining eye movement, said apparatus comprising a touch display, a memory, and a processor configured to repeat a set of steps, wherein said set of steps comprises determining a position of a contact point at which a user touches said display, said position being a determined position, locating a corresponding portion in an image that is being displayed on said touch display, generating a degraded image based on a stored image, displaying said degraded image on said touch display, and recording successive positions of said contact point, wherein said degraded image is substantially identical to said stored image within a clear zone thereof, wherein said clear zone includes said determined position and surroundings thereof, wherein said stored image is degraded beyond said clear zone by a peripheral degradation parameter.

Abstract
An eye-movement determination method includes providing an a touch display and a memory that stores an image that includes a point of interest, wherein the image is a stored image, and repeatedly executing a set of steps. The steps include determining a position of a contact point, locating a corresponding position in an image that is displayed on the touch display, generating a degraded image from the stored image, displaying the degraded image on the touch display, and recording successive positions of the contact point. The contact point is a point at which a user contacts the touch display. The degraded image is substantially identical to the stored image with a clear zone but degrades beyond the clear zone.

- 2. A method comprising determining eye movements, wherein determining eye movements comprises providing an apparatus, executing a set of steps and repeating execution of said set of steps, wherein said apparatus comprises a touch display and a memory that stores an image that includes a point of interest, wherein said image is a stored image, wherein said set of steps comprises determining a position of a contact point, locating a corresponding position in an image that is displayed on said touch display, generating a degraded image from said stored image, displaying said degraded image on said touch display, and recording successive positions of said contact point, wherein said contact point is a point at which a user contacts said touch display, wherein said degraded image is substantially identical to said stored image with a clear zone, wherein said clear zone includes said contact point and surroundings thereof, and wherein said image is degraded beyond said clear zone using a peripheral degradation parameter.
