1. A touch-sensitive apparatus comprising:
- a light source module configured to emit light;
a deformable waveguide coupled to the light source module and configured to transmit the light or a deflected version of the light at a situs at which pressure external to the deformable waveguide is applied, the deformable waveguide also being illuminated by the light; and
one or more sensors configured to detect information indicative of the light or the deflected version of the light at the situs and output a signal in response to the detected information.

Abstract
A touch-sensitive system, and apparatus, and method of operation of the apparatus, are provided. In one embodiment, the apparatus includes a light source module configured to emit light; and a deformable waveguide coupled to the light source module and configured to transmit the light or a deflected version of the light at a situs at which pressure external to the deformable waveguide is applied. The deformable waveguide may also be illuminated by the light. The apparatus may also include one or more sensors configured to detect information indicative of the light or the deflected version of the light at the situs, and output a signal in response to the detected information.

23. A method of operating a touch-sensitive apparatus having a light source module, a deformable waveguide coupled to the light source module, and one or more sensors coupled to the deformable waveguide, the method comprising:
-
emitting light from the light source module; transmitting, through the deformable waveguide, the light or a deflected version of the light at a situs at which pressure external to the deformable waveguide is applied; detecting, at the one or more sensors, information indicative of the light or the deflected version of the light at the situs; and outputting, from the one or more sensors, a signal in response to the detected information. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
