Abstract: Pressure sensitive key techniques are described. In one or more implementations, a device includes at least one pressure sensitive key having a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex responsive to pressure to contact the sensor substrate to initiate an input, for a computing device, associated with the pressure sensitive key. At least one of the flexible contact layer or the sensor substrate are configured to at least partially normalize an output resulting from pressure applied at a first location of the flexible contact layer with an output resulting from pressure applied at a second location of the flexible contact layer that has lesser flexibility than the first location.

Abstract: Techniques for mobile device application state are described. In one or more implementations, a mobile device includes a computing device that is flexibly coupled to an input device via a flexible hinge. Accordingly, the mobile device can operate in a variety of different power states based on a positional orientation of the computing device to an associated input device. In one or more implementations, an application that resides on a computing device can operate in different application states based on a positional orientation of the computing device to an associated input device. In one or more implementations, techniques discussed herein can differentiate between vibrations caused by touch input to a touch functionality, and other types of vibrations. Based on this differentiation, techniques can determine whether to transition between device power states.

Abstract: Accessory device authentication techniques are described. In one or more embodiments, connection of an accessory device to a host computing device is detected. Responsive to the detection, an authentication sequence may occur to verify an identity and/or capabilities of the accessory device. Upon successful authentication of the accessory device, the host device may authorize the accessory device for power exchange interactions with the host device. The host device may then draw supplemental power from a power source associated with the authorized accessory device, such as a battery or power adapter. The host device may also enable the accessory device to obtain and use power supplied by the host device in some scenarios. Power exchange between a host device and an authorized accessory may be managed in accordance with capabilities of the accessory device that are identified during authentication.
