    摘要: A system includes a touchpad sensor array, a touch circuit, and a proximity circuit. The touch circuit executes a touch mode configured to track the position of a user or conductive object on the touchpad sensor array by detecting a change in an electrical property of the touchpad. The proximity circuit executes a proximity detection mode configured to track the position of a user or conductive object near or proximate to the touchpad sensor array by detecting a change in an electrical property of the touchpad. The system is configured to switch from the touch mode to the proximity detection mode after a predetermined period of inactivity, where the proximity detection mode can operate at one or more reduced polling rates, resulting in a reduced overall power dissipation. The system is configured to switch back to the touch mode when activity is detected by the proximity circuit.

    摘要: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

    摘要: One aspect of the present invention is an apparatus and method for improved cursor control in a device which can operate both on a work surface and in air. Cursor resolution is reduced as the user engages with the device for clicking, leading to more precise movement closer to the target, as well as reduced parasitic and other unintentional motion of the cursor during clicking. Moreover, one aspect of the present invention is an apparatus and method for improved battery life in an in-air pointing device. In another aspect, the present invention is a method a system for improved user interface interaction, for UI controls such as sliders, pop-up boxes, menus, lists and button groups.

    摘要: To compensate for transmission errors of a non-ideal system for transmitting digital signals, first signal deviations are determined and stored, and then there is a direct processing of the input signals into output signals by combining the input signals with the stored signal deviations. The invention includes both method and apparatus and provides a substantial reduction in equipment costs.
