Abstract
Methods and devices for detecting touch, e.g. by a finger touching a touch-sensitive surface of the device, are disclosed. In particular, detection of touch can be by influencing, by touch, propagation of light within the touch-sensitive device and detecting a resulting change of light arriving to at least one detector device of the touch-sensitive device. Three paths for light can intersect (or at least substantially intersect) at a primary zone of intersection. Thus, three coordinates for a touch at the touch-surface may be provided, and a redundancy of coordinates may be provided for a touch.
