Abstract
The present invention relates to a method and a device for detection of position of touch. The device comprises a waveguide, at least one light source, and at least one detector device. The waveguide has a touch-surface with a surface structure defining a pattern that defines active surface areas and passive surface areas. The pattern is distributed such that an object that contacts a first area will cause a different disturbance of light than an object that contacts a second area, and such that correct positions of a plurality of concurrent touches may be detected.
