Method and apparatus for characterizing context of a mobile device

摘要

Information about a context of a mobile device is inferred using measurements from light detectors of the mobile device. The light detectors may be located on multiple different sides of the mobile device. In some embodiments, measurements from one or more cameras may be used to infer context.

1. A machine implemented method comprising:
receiving an image from a camera disposed to capture light impinging on a first surface of a mobile device; receiving one or more signals from an ambient light sensor responsive to light impinging on a second surface of said mobile device, the second surface being different from the first surface; performing an analysis comparing the image from the camera to at least a signal of the one or more signals from the ambient light sensor; determining a position status of the mobile device with respect to the environment of the mobile device, the determining the position status based, at least in part, on the analysis; and adjusting a parameter of the mobile device based on the determining of the position status of the mobile device.
