Abstract: An anticipated direction to a signal source is determined by a communication device having an antenna. The communication device receives video images in a field of view of a camera and determines, using sensors of the communication device, an antenna direction.

The antenna direction indicator indicates the antenna direction relative to the field of view of the camera, and the guiding icon represents a direction offset from the anticipated direction. An energy value of a signal received from the signals source is determined by the communication device using the antenna, and a position of the guiding icon on the display screen is updated based on the anticipated direction.
