A computer-implemented method of calibrating an electronic display screen for touchless gesture control using a calibration device, wherein the method comprises: displaying, by the electronic display screen, a calibration pattern; detecting, using at least one depth camera, a calibration device being placed on the electronic display screen and a reflection of at least a part of the calibration pattern, wherein the reflection is provided by a reflective surface of the calibration device; determining, based on the detected reflection, the position of the calibration device with respect to the displayed calibration pattern on the electronic display screen; defining a touchless gesture control input area for the electronic display screen being observable by the at least one depth camera.

Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction. Additionally, an energy detection receiver for IR-UWB is presented to similarly meet these design goals whilst being adaptable to address IR-UWB transmitter specificity.

A method for assembling a touch sensing apparatus comprising a display panel, a plate comprising a top surface and a bottom surface opposite the top surface, and a frame assembly, wherein the plate has a first curvature along at least a first edge of the top surface of the plate when uncoupled with the frame assembly. The method comprises the steps of arranging a plurality of light emitters alongside a periphery of the plate, the plurality of light emitters configured to emit light propagating over the top surface; arranging a plurality of detectors alongside the periphery of the plate, the plurality of detectors configured to receive light emitted from the plurality of light emitters; and coupling the display panel, the plate, and the frame assembly, wherein the step of coupling causes the first curvature of the plate to change to a second curvature.

A display device includes a substrate; a plurality of light emitting units disposed on the substrate; a plurality of light sensing units disposed on the substrate; a pixel defining layer partitioning the plurality of light emitting units and the plurality of light sensing units; and a touch electrode disposed on the pixel defining layer. A shape of a mesh hole defined by the touch electrode and in which the plurality of light sensing units are disposed is defined by the touch electrode, and is different from a shape of a mesh hole in which a first light emitting unit among the plurality of light emitting units is disposed.

A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image. Examples of image projection devices include LED-LCD based projection devices, DLP-based projection devices using LED or laser illumination in combination with micromirror arrays, etc.

The technology disclosed relates to enhancing the fields of view of one or more cameras of a gesture recognition system for augmenting the three-dimensional (3D) sensory space of the gesture recognition system. The augmented 3D sensory space allows for inclusion of previously uncaptured of regions and points for which gestures can be interpreted i.e. blind spots of the cameras of the gesture recognition system. Some examples of such blind spots include areas underneath the cameras and/or within 20-85 degrees of a tangential axis of the cameras. In particular, the technology disclosed uses a Fresnel prismatic element and/or a triangular prism element to redirect the optical axis of the cameras, giving the cameras fields of view that cover at least 45 to 80 degrees from tangential to the vertical axis of a display screen on which the cameras are mounted.
