Abstract: A user can capture an image of an object, using a computing device, to obtain information about that object. If a specular highlight (or other saturated region) is detected, the device can attempt to determine a location of a light source associated with the highlight. The device can then provide instructions as to a direction to move in order to reduce the presence of the specular highlight in subsequent images. Multiple images of the object can be captured and analyzed to generate a three-dimensional reconstruction of the environment, whereby a position of the light source can be determined. In other embodiments, movement of the specular reflections in response to movement of the device is used to determine a direction of the light source. In other embodiments, an image of the user is captured to determine the position of the light source based on shadows or reflections on the user.

Abstract: A processing device receives a schedule from a server, the schedule identifying delivery times for a set of items associated with the user device. At each delivery time, the processing device contacts the server to obtain one or more items from the server in accordance with the schedule.

Abstract: The location of an electronic device can be tracked and updated in order to provide a user of the device accurate directions from the user's current location to a target location, for various types of environments. Upon detecting a trigger (e.g., detecting a QR code or detecting an access point signal), an example device can switch from using a first type of positioning element (e.g., GPS) to a second type of positioning element (e.g., using accelerometers, QR codes, etc.) in determining the user's current location. By using the appropriate type of positioning element for each environment, the device may determine the user's current location more accurately. The device may provide an overlay (e.g., arrows) for displaying the directions over images captured from the user's surroundings to provide a more realistic and intuitive experience for the user.
