Abstract
Methods and systems related to the field of pointing devices are disclosed herein. One disclosed device has a pointing direction, a set of antennas including a first antenna and a second antenna, and at least one of an inertial measurement unit, a gravity sensor, and a magnetometer. The device also includes one or more computer readable media storing instructions which, when executed on the device, cause the device to: determine a difference between a signal as received by the first antenna and the signal as received by the second antenna; determine, using the difference, an angle between the pointing direction and a signal source direction of the signal; measure a physical quantity using the at least one of the inertial measurement unit, the gravity sensor, and the magnetometer; and determine a pointing target of the device using the angle and the physical quantity.
