Abstract: Various configurations and arrangements for touchscreens are disclosed to accommodate for one or more optical discontinuities that can be present within these touchscreens. When the one or more optical discontinuities are present, these configurations and arrangements of the touchscreens present a single layer of transparent conductive material that can be difficult to perceive by a human eye when viewing the touchscreens. Additionally, various edge correction techniques are disclosed to adjust mutual capacitances along a perimeter of the touchscreens. These edge correction techniques adjust mutual capacitances such that the values of the mutual capacitances are substantially uniform throughout.

Abstract: System, method, and computer program product embodiments are provided that can support touch interaction on a projective capacitive (PCAP) display system in the presence of water contamination. According to an embodiment, a system includes a touchscreen coupled to a controller. The controller determines the presence of water contamination on the touchscreen, and obtains measurements during a mixed-mode measurement frame that includes a self-mode measurement and a mutual-mode measurement. Based on the measurements obtained, the controller determines a touch on the touchscreen in the presence of the water contamination on the touchscreen. In some embodiments, the self-mode measurement includes measurements collected at a both lower and a higher drive frequency, the higher drive frequency may be in the frequency range of 100 kHz to 500 kHz. In another embodiment, the self-mode measurement includes simultaneously measuring both horizontal-electrodes and vertical-electrodes.

Abstract: Embodiments improve projected-capacitive (PCAP) touchscreen performance for applications subject to water contamination. Embodiments include: increased separation between indium-tin-oxide (ITO)/silver connection of an electrode terminus and routing traces, and increased separation between electrostatic discharge (ESD) lines and sensor guard lines. Embodiments may include methods for rejecting false touches from self-capacitance readout mode measurements due to long water drops/rivulets on a touchscreen including peak ratios and locations of peaks on perimeter electrodes. Some embodiments include an optically clear adhesive layer between a first transparent substrate including a first ITO coating forming a first set of electrodes, and a second transparent substrate including a second ITO coating forming a second set of electrodes.

Abstract: Deblurring a blurry image (14) includes the steps of (i) computing a spatial mask (256); (ii) computing a modified blurry image (264) using the blurry image (14) and the spatial mask (256); and (iii) computing a latent sharp image (16) using the modified blurry image (264) and a point spread function (260). Additionally, the image (714) can be analyzed to identify areas of the image (714) that are suitable for point spread function estimation. Moreover, a region point spread function (1630) can be analyzed to classify the point spread function(s) as representing (i) motion blur, (ii) defocus blur, or (iii) mixed motion blur and defocus blur. A point spread function (2670) can also be estimated.

Abstract: System, method, and computer program products are provided that can support touch interaction from multiple users on a large scale projective capacitive (PCAP) display system, such as a gaming table. According to some embodiments, a system includes a touchscreen coupled to a controller. The controller adjusts performance of the touchscreen through dynamically setting a controller parameter to support altered touch reporting in a first area of the touchscreen compared to a second area of the touchscreen. The controller enables touch detection for the first area according to performance characteristics needed for an application operating in the second area. Some embodiments include the controller identifying a user associated with the first area, where the controller receives and analyzes a watermarked touch signal from the first area that includes a touch signal and a unique signal, detects an associated touch location, and detects the unique signal associated with the user.
