Abstract

A user input apparatus for detecting direction and/or input position of a light beam (303) incident on the apparatus from a light beam generating device (305). The apparatus comprises a light guiding layer (301) configured to direct at least a fraction of the light beam (303) towards light detecting means, and the light guiding layer (301) comprises a first array of optical structures (320a) and at least a second array of optical structures (320b) configured to direct the light beam in at least four directions (304a, 304b) towards the light detecting means.
