    摘要： In embodiments of angular contact geometry, touch input sensor data is recognized as a touch input on a touch-screen display, such as a touch-screen display integrated in a mobile phone or portable computing device. A sensor map is generated from the touch input sensor data, and the sensor map represents the touch input. The sensor map can be generated as a two-dimensional array of elements that correlate to sensed contact from a touch input. An ellipse can then be determined that approximately encompasses elements of the sensor map, and the ellipse represents a contact shape of the touch input.

    摘要： A method of interacting with a computing device via one or more inking instruments to generate digital ink may include the steps of emitting light from a light emitting device to an inking instrument, receiving first user inputs from the inking instrument, and identifying the inking instrument based on sensed light reflected from the inking instrument. Another method may include the steps of simultaneously detecting first user inputs from a first inking instrument and second user inputs from a second inking instrument by receiving first light emitted from the first inking instrument and second light emitted from a second inking instrument that each have one or more identifying characteristics, identifying the inking instrument based on their identifying characteristics, and generating corresponding digital ink. These methods may be implemented via computer-executable instructions and may be used with a horizontally-placed display, tablet-based laptop computers, and passive or active digital inking instruments.

    摘要： Embodiments that relate to determining gaze locations are disclosed. In one embodiment a method includes shining light along an outbound light path to the eyes of the user wearing glasses. Upon detecting the glasses, the light is dynamically polarized in a polarization pattern that switches between a random polarization phase and a single polarization phase, wherein the random polarization phase includes a first polarization along an outbound light path and a second polarization orthogonal to the first polarization along a reflected light path. The single polarization phase has a single polarization. During the random polarization phases, glares reflected from the glasses are filtered out and pupil images are captured. Glint images are captured during the single polarization phase. Based on pupil characteristics and glint characteristics, gaze locations are repeatedly detected.

    摘要： For use in a set-top box, a relatively small line buffer and a frequency control permit scaling of a video input signal and synchronization between the input signal and a composite output signal. Image data and timing signals derived from the video signal are applied to a video capture engine (VCE). When scaling the input video, the VCE combines an appropriate number of successive lines of the field being processed to produce scaled scan line data for use by a dynamic composition engine (DCE) in producing the composite image. A video odd timing signal is applied to an input odd register, which is monitored by a central processing unit (CPU). The CPU controls the values in a frequency register and in an output odd register. The value in the frequency register determines the frequency of an output clock. The signal from the output clock is applied to a horizontal timing logic circuit that produces an output horizontal sync signal. By adjusting the values in the frequency register and in the output odd register, the CPU is able to control synchronization of the composite image and to determine whether the scaled video is rapidly synchronized with the input signal or is allowed to synchronize more slowly, after a change occurs in the video source. Preference can thus be given either to the stability of the digital signal portion of the composite image or to the scaled video data.

    摘要翻译： 为了在机顶盒中使用，相对较小的行缓冲器和频率控制允许视频输入信号的缩放和输入信号与复合输出信号之间的同步。 从视频信号导出的图像数据和定时信号被应用于视频采集引擎（VCE）。 当缩放输入视频时，VCE组合正在处理的字段的适当数量的连续行，以产生缩放的扫描线数据，供动态组合引擎（DCE）在生成合成图像时使用。 视频奇数定时信号被施加到由中央处理单元（CPU）监视的输入奇数寄存器。 CPU控制频率寄存器和输出奇数寄存器中的值。 频率寄存器中的值决定输出时钟的频率。 来自输出时钟的信号被施加到产生输出水平同步信号的水平定时逻辑电路。 通过调整频率寄存器和输出奇数寄存器中的值，CPU能够控制合成图像的同步，并确定缩放后的视频是否与输入信号快速同步，或者允许同步更慢 在视频源中发生变化。 因此，优先权可以被提供给合成图像的数字信号部分或缩放的视频数据的稳定性。
