摘要： 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 deduced.

摘要： The present invention relates to a method and a device for detecting touch, e.g. by a finger touching a touch-surface of the device. In particular the invention relates to detection of touch by means of influencing, by means of the touch, propagation of light within the touch-sensitive device and detecting resulting change of light arriving to at least one detector device of the touch-sensitive device. Three paths for light intersect (or at least substantially intersect) at a primary zone of intersection. Thus, three coordinates for a touch at the touch-surface may be provided and a redundancy of coordinates may be provided for a touch.

摘要： The present invention relates to a device for encoding a position of an object, comprising a first light source; a first collimating element adapted to form first collimated light from the first light source; a carrier adapted to guide light and comprising a first primary light redirecting structure and a second primary light redirecting structure; and a detector device for encoding the position of an object with respect to an active area of an encoding plane; wherein the first primary light redirecting structure is adapted to redirect at least a part of a first light beam through the active area into the second primary light redirecting structure; and wherein the second primary light redirecting structure is adapted to redirect light received from the first primary light redirecting structure onto the detector device. Thereby is achieved that a collimated light beam is propagated along the carrier and from the carrier into the active area via the first primary light redirecting means. The collimated light ensures a controlled part of the carrier is utilized for the propagation of the collimated light.

摘要： 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.

摘要： The present invention relates to an interactive system and a method for encoding, e.g. position encoding, a touch by an object. The system comprises a display, a waveguide for guiding light, which waveguide is displaceable in relation to the display, a first light source for emitting light into the waveguide, and a detector for detecting light from the waveguide. The waveguide may be in a first position next to the display, and in a second position displaced in relation to the display. When the waveguide is in the first position, a first surface of the waveguide is a touch-sensitive surface, such that the object touching the first surface disturbs at least a part of the light from the first light source, the disturbance of the light being detectable at the detector. Thus, encoding of the touch is enabled.
