Beschreibung
Zusammenfassung:	The present invention relates to an encoding device, such as an optical position encoder, for encoding input from an object, and a method for encoding input from an object, for determining a position of an object that interferes with light of the device. The encoding device comprises a light source, a waveguide, a number of redirecting structures, and a detector. By means of the waveguide and the number of redirecting structures, light from the light source is guided towards the detector along a path that includes traversing an area in a space next to the planar waveguide. An object may be positioned in the area in the space and may interfere with the light, which interference may be encoded into a position or activation.
