    • A tactile touch-sensitive device for use as an electronic input device for indicating a position of an electronic document on a display device is described. The illuminable document position indicator aspect of the device provides a relative location of the electronic document on the display. The device may be included as part of a keyboard or an electronic book device. The illuminable document position indicator may be one or more static illuminable LEDs and/or a moveable light source and pivotable translucent elements which act as light wave guides. A controller may be used to control the illuminable document position indicator. The controller may change the color and/or intensity of LEDs based upon a displayed location of the electronic document relative to a beginning and an end of the electronic document.

    • Capacitive proximity sensing is carried out by detecting a relative change in the capacitance of a “scoop” capacitor formed by a conductor and a surrounding ground plane. Charge is transferred between the “scoop” capacitor and a relatively large “bucket” capacitor, and a voltage of the bucket capacitor is applied to an input threshold switch. A state transition (e.g., from low to high, or high to low) of the input threshold switch is detected and a value (TouchVal) indicative of a number of cycles of charge transfer required to reach the state transition is determined. The presence or absence of an object or body portion in close proximity to or contact with a device can be determined by comparing TouchVal with a predetermined threshold value (TouchOff). In order to lessen the time required for detection, and/or improve the sensitivity thereof, the bucket capacitor may initially be charged to a repeatable non-zero reference level closer to the charge level that will cause a state transition. TouchOff can be adjusted to take into account environmentally induced (non-touch related) changes in the capacitance of the scoop capacitor. Power management may be provided in a user operated data input device utilizing the inventive proximity sensing.
    • 通过检测由导体和周围地平面形成的“勺”电容器的电容的相对变化来进行电容接近感测。 在“勺”电容器和相对较大的“桶”电容器之间传送电荷,并且将桶式电容器的电压施加到输入阈值开关。 检测输入阈值开关的状态转换(例如,从低到高或高到低),并且确定指示达到状态转换所需的电荷转移周期数的值(TouchVal)。 可以通过将TouchVal与预定阈值(TouchOff)进行比较来确定与设备紧密接触或接触的物体或身体部分的存在或不存在。 为了减少检测所需的时间和/或提高其灵敏度,桶式电容器可以最初被充电到更接近导致状态转换的充电电平的可重复非零参考电平。 可以调整TouchOff以考虑到勺式电容器的电容的环境诱导(非触摸相关)变化。 可以在利用本发明的接近感测的用户操作的数据输入装置中提供电源管理。

    • A data input device for use with a tracking surface having light-scattering properties. The device comprises a coherent light source for projecting a coherent light beam onto the tracking surface to reflect a speckle pattern. A detector having a field of view detects and images the speckle pattern. The detector operates in a tracking mode when the field of view intersects the coherent light beam. The intersection of the coherent light beam and the field of view comprise a detection zone. Relative movement between the coherent light beam and the tracking surface within the detection zone between is detected in the tracking mode, based on the reflected speckle pattern. Relative movement between the coherent light beam and the tracking surface outside the detection zone is not detected. A controller responsive to the detector operates in the tracking mode for correlating the imaged laser speckle pattern to track the relative movement within the detection zone.
