    摘要: An input device providing integrated contact switch and touch sensor elements is disclosed. A contact switch and touch sensor can be integrated so that they share a common sensor line, achieving space, cost and manufacturing savings over input devices that utilize distinct sensor lines for each of its sensor elements. By configuring a contact switch and touch sensor to share a common sensor line, a controller can use a single pin to scan both the contact switch and touch sensor elements, rather than using distinct pins to scan distinct sensor lines associated with each sensor element. By using fewer pins to scan the same number of sensor elements, a smaller controller can be used which can reduce the size and cost of the input device, and increase manufacturing throughput time associated with the input device.

    摘要: A curved surface input device with normalized capacitive sensing is disclosed. The input device can normalize capacitive sensing through an overlay having a varying thickness, such as an overlay with a curved surface. The capacitive sensing normalization can be implemented in software, hardware or a combination of software and hardware. A software implementation for normalizing capacitive sensing can comprise adjusting the sensitivity of a sensing operation associated with different sensor elements of the input device. A hardware implementation for normalizing capacitive sensing can comprise adjusting a hardware configuration of the input device associated with one or more physical parameters that can influence the capacitive sensitivity of the sensor elements, such as an area of the sensor elements, a distance between the sensor elements and other conductive input device elements (such as a ground plane), and a dielectric constant associated with the overlay.

    摘要: An input device with switchable sensor configurations. In one embodiment, the input device can switch between a sensor configuration in which each of its sensor elements is enabled to sense input and a sensor configuration in which only a subset of its sensor elements are enabled to sense input. In another embodiment, the input device can switch between a sensor configuration in which each of its sensor elements is enabled to sense input and a sensor configuration in which one or more groupings of its sensor elements are enabled to collectively sense input. In a further embodiment, the input device can operate in a detection mode that switches between sensor configurations to determine a position of an input.
