  • Patent number: 8933896
    Abstract: In an indirect interaction input device, z-information can be considered in defining a user interaction model for the device. Any measurement of displacement in a z-direction can be used, if such information is available from the input device. The pressure data can be used to define states of interaction, with transitions between these states determined by various thresholds. The device can provide raw or normalized data, and can provide state information or data defining its thresholds that specify state transitions. This information can be provided as an attribute of a contact point provided by the device. Data can be normalized across various similar devices. Applications can use the raw pressure data from the device for their own purposes, or rely on the device itself or host operating system software to interpret the pressure data according to thresholds and states.

  • Patent number: 8933872
    Abstract: A liquid crystal display includes: a light source unit that includes a light-guiding plate with a light-exit plane partitioned into emission subsections, and one or plural sides, and light sources; a liquid-crystal-display panel that includes pixels, and modulates light emitted from the light source unit, thereby performing image display; and a display control unit that includes a partitioning-drive processing section generating each of a light-emission pattern signal and a partitioning-drive image signal, performs light-emission driving for each light source, and performs display driving for each pixel. The partitioning-drive processing section performs a gain correction of multiplying each pixel signal in the input image signal by a predetermined gain factor that is set so that a value increases as a pixel position of the pixel signal goes away from the light source, and generates the light-emission pattern signal and the partitioning-drive image signal, by using gain-corrected pixel signal.

  • Patent number: 8913044
    Abstract: At a writing time, a first transistor 412 is turned on so that a data signal Xj is supplied to one end of a capacitor 420. At this time, since a second transistor 414 is turned off, driving current does not flow to an organic light emitting diode (OLED) device 430. A power supply voltage Vdd is supplied to the other end of a capacitor through a power supply line L. However, since the driving current does not flow at the writing time, the power supply voltage Vdd is not reduced by the wiring line resistance of the power supply line L. On the other hand, at an emission time, the first transistor 412 is turned off and the second transistor 414 is turned on. Therefore, the driving current is supplied to the OLED device 430.

  • Patent number: 8860693
    Abstract: Image processing techniques that can improve the user interface experience associated with key-based input devices. In one embodiment, a motion sensitive mechanical keyboard can utilize orthogonally-oriented cameras to sense hand/finger motion over the surface of the keys. This arrangement can enable a standard look and feel mechanical keyboard to receive command and cursor input (e.g., pointing and gestures) from the user without requiring the user to move the user's hand off the keyboard. The image processing techniques can be utilized to minimize or remove undesirable cursor movement that can occur based on certain detected hand/finger motion from such cameras, including looming and/or vertical motions for example.

  • Patent number: 8854319
    Abstract: Transducers formed as part of a touchscreen system emulate the motion of a pushbutton or other mechanical elements. A touchscreen system positions a transducer adjacent to an icon displayed on the touchscreen surface. When a user touches the icon, the transducer senses the touch and is then deformed in a pattern that emulates a mechanical motion, giving the user the sensation of touching a mechanical button. An excitation signal applied to the transducer is compared to a target excitation signal that, when applied to the transducer, causes the transducer to emulate the desired motion. When any differences between the two signals are detected, the excitation signal is adjusted so that the motion is corrected. The target excitation signal, or time and voltage segments defining it, are stored in memory and retrieved for comparison. The excitation signal is also selected to reduce any acoustic artifacts that can cause the transducer to generate audible clicks.
