Touch region projection onto touch-sensitive surface
First Claim
1. A computing system comprising:
- a touch-sensitive surface;
a camera to capture an image representing an object disposed between the camera and the touch-sensitive surface;
a detection engine to identify, based at least on the object represented in the image, a touch region associated with the touch-sensitive surface, the touch region comprising at least one of a target touch region and a non-target touch region, wherein input within the target touch region is to be accepted and input within the non-target touch region is to be rejected;
a projection engine to generate a projection image comprising a projected region corresponding to the target touch region; and
a projector to project the projection image, including the target touch region, onto the touch-sensitive surface,wherein the object is a hand and the non-target touch region corresponds to an area on the touch-sensitive surface over which a palm of the hand is disposed.

Abstract
Examples disclosed herein relate to projecting onto a touch-sensitive surface a projection image having projected regions corresponding to target and non-target touch regions. Examples include a computing system having a touch-sensitive surface, and a camera to capture an image representing an object disposed between the camera and the touch-sensitive surface. The computing system may also include a detection engine to identify, based at least on the object represented in the image, at least one touch region of the touch-sensitive surface, and to generate a projection image including a projected region corresponding to the touch region, and a projector to project the projection image onto the touch-sensitive surface.

6. A non-transitory machine-readable storage medium comprising instructions executable by a processing resource of a computing system comprising a touch-sensitive surface and a camera, the instructions executable to:
-
acquire, from the camera, an image representing an object disposed between the camera and the touch-sensitive surface; identify a current touch input scenario of a plurality of touch input scenarios; identify a touch region of the touch-sensitive surface based at least on the current touch input scenario and a location of a portion of the object as represented in the image, the touch region comprising a target touch region and a non-target touch region, wherein input within the target touch region is to be accepted and input within the non-target touch region is to be rejected; and project a projection image onto the touch-sensitive surface, the projection image comprising a projected region corresponding to the identified touch region, wherein the object is a hand and the non-target touch region corresponds to an area on the touch-sensitive surface over which a palm of the hand is disposed. - View Dependent Claims (7, 8, 9, 10)

11. A method comprising:
-
detecting an object on or above a touch-sensitive surface; determining a target touch region of the touch-sensitive surface based on a portion of the detected object associated with touch input; determining a non-target touch region of the touch-sensitive surface over which a palm of a hand is disposed; projecting a projection image on the touch-sensitive surface, the projection image comprising projected region corresponding to the target touch region and the non-target touch region, wherein input within the target touch region is to be accepted and input within the non-target touch region is to be rejected; and rejecting an input touch to the non-target touch region, wherein the object is a hand and the non-target touch region corresponds to an area on the touch-sensitive surface over which a palm of the hand is disposed. - View Dependent Claims (12, 13, 14)
