The apparatus comprises a planar light guide, a plurality of light emitters arranged to emit light into the light guide for propagation by total internal reflection inside the light guide, and a plurality of light detectors, each being arranged to detect at least a portion of the emitted light propagating inside the light guide and at least a portion of the ambient light, said detectors being distributed along the periphery of the touch surface such that the optical plane of detection of light coincides with the plane of the light guide, at least one of said detectors being adapted to detect light emitted by an external device configured to emit light. The apparatus also comprises a processor unit configured to, ultimately, generate a digital signal containing data regarding light generated by the external device. Invention also regards a method for enabling control of a touch-sensing apparatus by an external device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch-sensing apparatus and a method for enabling control of a touch-sensing apparatus by an external device","description":"Invention principally regards a remotely controllable touch-sensing apparatus.
