Abstract: A method of videoconferencing comprises displaying an image of a remote user on a display and capturing an image of a local user at a user position in front of the display. The at least one camera is located at a camera position behind the display. The method comprises modifying an image to be displayed based on the camera position of the at least one camera with respect to the display and based on the user position of the local user with respect to the display.

Abstract: A touch system is described having a method of determining touch of one or more objects on a touch surface of a touch-sensitive apparatus, wherein the method operates in a time sequence of frames, each frame comprising the steps of: for a current frame, processing an output signal of the touch sensitive apparatus to generate one or more touch traces, each touch trace having one or more characteristics; and outputting a confirmed touch signal for each touch trace having a touch trace matching at least one of said one or more characteristics in a first number of frames preceding the current frame, wherein the first number of frames is determined in dependence on said one or more characteristics.

Abstract: A solar panel is described, the solar panel comprising a light transparent panel, a photo luminescent layer configured to absorb light of a first wavelength spectrum and emit light at a photo luminescent wavelength into the light transparent panel to propagate in the light transparent panel via total internal reflection, one or more photovoltaic components located at a periphery of the light transparent panel and configured to receive light propagating in the light transparent panel via total internal reflection and convert said light to electrical energy.
