    Abstract: An input device for an electronic device includes an enclosure and a top member defining an input surface having multiple differentiated input regions. The input device further includes a first force sensing system associated with a first area of the top member and including a first group of the differentiated input regions, and a second force sensing system associated with a second area of the top member and including a second group of the differentiated input regions. The input device further includes a touch sensing system configured to determine which input region from the first group of the differentiated input regions corresponds to the first force input and to determine which input region from the second group of the differentiated input regions corresponds to the second force input.

    Abstract: Embodiments are directed to a low profile key for a keyboard having an overmolded support structure. In one aspect, an embodiment includes a key cap having an illuminable symbol. A support structure having a pair of overmolded wings may pivotally couple to the key cap. A switch housing may surround the support structure and connect each of the first and second wings. A tactile dome may be at least partially positioned within the switch housing and configured to bias the key cap upward. A sensing membrane may be positioned along an underside surface of the tactile dome and configured to trigger a switch event in response to a collapsing of the tactile dome caused by a depression of the key cap. A feature plate may be positioned below the sensing membrane. A light guide panel may define at least one light extraction feature that may be configured to propagate light toward the key cap and cause illumination of the illuminable symbol.

    Abstract: An input device, such as a stylus, can include a piezoelectric device for providing haptic feedback and/or detecting user input. The piezoelectric device can be coupled to an inner surface of a housing of the stylus. The piezoelectric device can provide haptic feedback with a force to the housing when an electric voltage is applied to the piezoelectric device. The haptic feedback can provide information to the user relating operation of the stylus with an external device. The piezoelectric device can also produce an electric voltage when an input force is applied to an outer surface of the housing and transmitted to the piezoelectric device. The electric voltage can be used to detect tactile input from a user.

    Abstract: A keyboard may be provided that has keys overlapped by a touch sensor. The keyboard may have key sensor circuitry for monitoring switching in the keys for key press input. The keyboard may also have touch sensor circuitry such as capacitive touch sensor circuitry that monitors capacitive electrodes in the touch sensor for touch sensor input such as multitouch gesture input. The keyboard may include an outer layer of fabric that overlaps the keys. The fabric may have openings that are arranged to form alphanumeric characters. Light sources may emit light that passes through the openings and illuminates the alphanumeric characters. The touch sensor may have signal lines that are not visible through the openings. The signal lines may be transparent, may be covered by a diffuser, or may circumvent the openings so that they do not overlap.
