    Abstract: A detector for optical detection of location within a volume, comprises a beam source for shining a structured light pattern on the volume and a digital detector having detection pixels of a given size. The light pattern, when shone into the volume and reflected back to the detection pixels, has a brightness distribution with a peak and a surrounding brightness structure. Now often the peak may be smaller than the pixel size although the overall distribution of the brightness extends over multiple pixels. The system includes an electronic processor for assessing a distribution of brightness among the neighbouring pixels to infer a location of the peak within a region smaller than the size of the central pixel on which it falls, thus giving sub-pixel resolution.

    Abstract: A method and a system for generating user feedback of a gesture capturing device with content projection capability are provided herein. The method may include the following steps: projecting content, by a content projector, onto a projection surface; projecting patterned light, by a pattern projector, onto said projection surface and onto a maneuverable object controlled by a user; capturing reflections of the patterned light coming from said projection surface and said maneuverable object; calculating, based on said reflections, at least one of: a relative position and a relative orientation of at least two of: said projection surface, said maneuverable object, said content projector and said pattern projector; and generating a feedback, based on said calculated relative positions and/or orientations, wherein said feedback relates to a proper operation of the system, based on said relative position and a relative orientation, in view of predefined criteria.

    Abstract: An optical sensing device for using light to locate objects or features in a field of view comprises a light source; a controllable lens having two states and being controllable between them, for example a multifocal lens having two or more foci for focusing light from the light source; and a sensor able to sense light reflected from an object, to determine information of the object. The use of two or more foci adds dynamic range to optical sensing to allow for reliable detection over a wide range of distances.
