Abstract: The touch panel includes a panel capacitor, a first circuit, a first capacitor, a second circuit and a controlling circuit. The first capacitor is coupled to the panel capacitor. The first circuit transmits a scan signal to the panel capacitor. The second circuit transmits an inverting signal to the first capacitor. The inverting signal is synchronized with the scan signal, a frequency of the inverting signal is identical to a frequency of the scan signal, and the inverting signal is phase-inverted from the scan signal. The controlling circuit outputs a touch signal in response to a voltage at a terminal of the panel capacitor, in which the touch signal is configured to estimate a capacitance of the panel capacitor.
Abstract: Disclosed herein is a touch sensor, including: a transparent substrate; and an electrode pattern formed on the transparent substrate, wherein the electrode pattern is formed in a mesh pattern and the mesh pattern includes at least one of the irregular unit patterns. Each unit pattern forming the mesh pattern may be formed in a polygonal shape.
Abstract: Correlating pupil position to gaze location within a scene. Illustrative embodiments may include correlating pupil position of a user to gaze location within a scene viewed by the user. The correlating may include: illuminating an eye of the user, the eye containing the pupil, and the illuminating with light; creating a first video stream depicting the eye; creating a second video stream depicting the scene in front of the user; determining pupil position within the first video stream; calculating gaze location in the second video stream based on pupil position in the first video stream; and sending an indication of the gaze location in the second video stream to a computer system.
Abstract: A method of controlling an electro-optical device includes controlling a driving section such that, when an image is rewritten from a first image displayed in a first gradation to a second image including a background image portion to be displayed in the first gradation and a main image portion to be displayed in a second gradation, the same potential as a counter electrode is supplied to a pixel in the background image portion, and a potential corresponding to the second gradation is supplied to a pixel in the main image portion. The driving section is controlled such that at least one of the magnitude and application time of a voltage applied between the pixel electrode and the counter electrode is smaller in a pixel corresponding to an edge portion in the main image portion than in a pixel corresponding to a non-edge portion in the main image portion.
