1. A method of view direction determination, the method comprising:
- obtaining, at a mobile device configured to receive sensor data generated by one or more light sensors of a head-mountable apparatus via wireless communication, a request to determine an approximate user view direction, wherein;
the approximate user view direction comprises an approximate field of view of a user wearing the head-mountable apparatus, and the sensor data is generated by the one or more light sensors in response to detecting light from one or more modulated light sources;
based on the request to determine the approximate user view direction, sending a request for the sensor data via wireless communication from the mobile device to the head-mountable apparatus;
receiving, in response to sending the request for the sensor data, the sensor data;
obtaining, for each of the one or more modulated light sources, location information of the respective modulated light source;
determining, with a processing unit of the mobile device, the approximate user view direction based, at least in part, on the sensor data and the location information; and
generating, with a processing unit, information indicative of the approximate user view direction.

Abstract
Techniques described herein, which may provide for a location determination of a mobile device, can also provide for the determination of a viewing direction of a user of the mobile device. In particular, a user can wear a head-mountable apparatus with one or more light sensors configured to detect light from one or more modulated light sources. Using this information, not only may a location of the head-mountable apparatus be determined, but also an orientation, which can enable a determination of an approximate direction the user is looking.
