  • Patent number: 8508481
    Abstract: A method, system, and medium are provided for improving the accuracy of keystroke detection by determining what finger position a person is using to type. The finger, or fingers, used to contact the keys may define a finger position. Once the finger position is detected, hot spots for individual keys may be positioned according to a profile associated with the finger position. The hot spot is the portion of the touch screen that needs to be contacted in order to register a keystroke for the associated key. Each key has its own hot spot. The hot spot for a key may change without the display of the key on the touch-screen keyboard changing.

  • Patent number: 8487912
    Abstract: In one embodiment, control circuitry receives an indication of a current position of an input object on a capacitive touch sense device. The control circuitry determines whether a difference between a previous position and the current position exceeds a predetermined hysteresis threshold. If the determined difference does not exceed the predetermined hysteresis threshold, the control circuitry masks the current position of the input object on the capacitive touch sense device.

  • Patent number: 8487877
    Abstract: A method and apparatus of identifying and selecting characters from among a plurality of characters. In accordance with one embodiment of the invention, a computer processor electronically enables identification of each of a plurality of characters arranged in a one-dimensional array. Each character is identified by an integer value that corresponds to the number of positions the character is offset from a reference position of the one-dimensional array. The computer processor electronically enables selection of any of the characters by receiving input resulting from activation of selection keys that specify the integer value of a character desired for selection. In one further embodiment, each selection key has an assigned integer value, and the integer value that identifies the selected character is calculated by summing the assigned integer values of each selection key activated for each instance that each selection key is activated within a selectable-length time period.

  • Patent number: 8466861
    Abstract: A liquid crystal display device displays an image by stacking a plurality of liquid crystal panels, and by controlling a light transmittance with voltage application to liquid crystal of each panel, wherein during execution of voltage application to the liquid crystal of one of the panels, a voltage to the liquid crystal of the other panel serves as a non-display voltage. No image is displayed simultaneously on the two or more stacked liquid crystal panels. In the liquid crystal panel to which no voltage is applied and on which no image is displayed, the longitudinal axial direction of liquid crystal molecules coincides with the polarizing axial direction of polarizers, or is orthogonal to the polarizing axial direction; therefore, no influence is exerted on the overall double refraction, and the overall voltage-transmitted light intensity characteristic corresponds to the sum of the voltage-transmitted light intensity characteristics of the respective panels.

  • Patent number: 8373655
    Abstract: Disclosed herein are methods and systems for providing a user interface (UI) having a selector controllable by a physical input device. The response of the selector is adaptively adjusted to facilitate executing desired operations within the UI. A response factor defines how far the selector moves for a given movement of the physical input device. The response factor is increased so the selector can be moved a large distance, but is dynamically decreased to provide fine-tuned control of the selector for selecting densely grouped screen elements. Screen elements can be endowed with gravity, making them easy to select, or with anti-gravity, making them more difficult to select. The disclosure methods also provide tactile feedback such as vibration or braking of the physical input device to assist a user in executing desired operations.
