Abstract:
Input device assembly techniques are described. In one or more implementations, an input device includes a key assembly including a plurality of keys that are usable to initiate respective inputs for a computing device, a connection portion configured to be removably connected to the computing device physically and communicatively to communicate signals generated by the plurality of keys to the computing device, a flexible hinge that physically connects the connection portion to the key assembly, and an outer layer that is configured to cover the plurality of keys of the key assembly, form an outer surface of the flexible hinge, and is secured to the connection portion such that the outer layer wraps around at least two sides of the connection portion.
Abstract:
Techniques for device camera angle are described. In one or more implementations, a camera is mounted in a computing device at an angle based on an orientation of the computing device. For example, when the computing device is positioned on a surface and at an angle to the surface (such as when supported by a kickstand), the mounting angle of the camera is such that an optical axis of the camera points forward, and not towards the surface. In at least some implementations, a computing device includes a camera that is physically adjustable to support different orientations of the computing device. In at least some implementations, images that are captured via a camera on a computing device can be manipulated based on an orientation of the computing device.
Abstract:
A pressure sensitive keyboard includes multiple pressure sensors associated with the keys of the keyboard. In response to pressure applied to one or more keys of the keyboard, a determination is made as to whether the pressure applied is a key strike (a user selection of a key). Various different factors can be used in determining whether the pressure applied is a key strike, such as the amount of the pressure applied, a rate at which the pressure is applied, a number of keys to which pressure is applied, when the pressure is applied relative to previous key strikes, and so forth.
Abstract:
A computing system includes one or more input-device user-interface runtime applications to dynamically display images on a dynamic input device. The one or more input-device user-interface runtime applications are executed in a currently active desktop. The computing system further includes a dominant application configured to execute in the currently active desktop. The dominant application is configured to specify an input-device user-interface runtime application corresponding to a current context of the dominant application. The specified input-device user-interface runtime application is configured to dynamically display virtual controls on the dynamic input device. The specified input-device user-interface runtime application is also configured to report activation of the virtual controls to the dominant application.

Various embodiments of systems and methods to implement a context-based state change for an adaptive input device are provided. For example, a method is disclosed that may include receiving a state input indicating a change in a system state, changing adaptive input device data in response to the state input, the adaptive input device data including one or more of image data or adaptive input device mapping data, and adjusting an adaptive input device display state using the adaptive input device data. Adjusting the adaptive input device display state may include one or more of displaying the image data on an adaptive input device display or adjusting an adaptive input device mapping state according to the adaptive input device mapping data.
Abstract:
Force concentrator techniques are described. In one or more implementations, a pressure sensitive key includes a sensor substrate having a plurality of conductors, a flexible contact layer spaced apart from the sensor substrate and configured to flex to contact the sensor substrate to initiate an input; and a force concentrator layer disposed proximal to the flexible contact layer on a side opposite the sensor substrate. The force concentrator layer has a pad disposed thereon that is configured to cause pressure applied to the force concentrator layer to be channeled through the pad to cause the flexible contact layer to contact the sensor substrate to initiate the input.
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:
Sensor fusion algorithm techniques are described. In one or more embodiments, behaviors of a host device and accessory devices are controlled based upon an orientation of the host device and accessory devices, relative to one another. A combined spatial position and/or orientation for the host device may be obtained based on raw measurements that are obtained from at least two different types of sensors. In addition, a spatial position and/or orientation for an accessory device is ascertained using one or more sensors of the accessory device. An orientation (or position) of the accessory device relative to the host computing device may then be computed based on the combined spatial position/orientation for the host computing device and the ascertained spatial position/orientation for the accessory device. The relative orientation that is computed may then be used in various ways to control behaviors of the host computing device and/or accessory device.
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.

Input device adhesive techniques are described. A pressure sensitive key includes a sensor substrate having one or more conductors, a spacer layer, and a flexible contact layer. The spacer layer is disposed proximal to the sensor substrate and has at least one -opening. The flexible contact layer is spaced apart from the sensor substrate by the spacer layer and configured to flex through the opening in response to an applied pressure to initiate an input. The flexible contact layer is secured to the spacer layer such that at first edge, the flexible contact layer is secured to the spacer layer at an approximate midpoint of the first edge and is not secured to the spacer along another portion of the first edge and at a second edge, the flexible contact layer is not secured to the spacer layer along an approximate midpoint of the second edge.
