Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, provide for one or more items of electronic content, or selected portions thereof, to be loaned or shared directly from one device to another device. A share event may be initiated by tapping, bumping, or other physical contact between the two devices, or by proximity of the two devices. During the share event, and/or at other times, one or more offers to purchase share opportunities associated with the item of electronic content may be presented on the loaner's device and/or the recipient's device. If a share request is approved, a copy of the item(s) of electronic content may be transferred directly from the loaner's computing device to the recipient's computing device, or may be transferred from a server at a later time.

Abstract: A computing device includes an image capture device, a display, and at least one processor. The image capture device is configured to capture a digital enrollment image of a face of an authorized user and a digital authentication image of a face of an authenticating user. The display is configured to present the enrollment and authentication images. The at least one processor is configured to automatically alter the authentication image for presentation by the display and compare the authentication image to the enrollment image to unlock the computing device for use by the authenticating user.

Abstract: A system and method for determining which key value in a set of key values is to be assigned as a current key value as a result an object intersecting a region where a virtual interface is provided. The virtual interface may enable selection of individual key values in the set. The position is determined using a depth sensor that determines a depth of the position in relation to the location of the depth sensor. A set of previous key values that are pertinent to the current key value may also be identified. In addition, at least one of either a displacement characteristic of the object, or a shape characteristic of the object is determined. A probability is determined that indicates the current key value is a particular one or more of the key values in the set.

Abstract: A light-generated input interface is provided using a combination of components that include a projector and a sensor. The projector displays an image corresponding to an input device. The sensor can be used to detect selection of input based on contact by a user-controlled object with displayed regions of the projected input device. An intersection of a projection area and an active sensor area on a surface where the input device is to be displayed is used to set a dimension of an image of the input device.
