1. A method for determining a position of a user, comprising:
- receiving a relative change in direction input from the user via a graphical user interface;
determining a distance traversed by the user, wherein determining the distance traversed by the user is selected from the group consisting of detecting rotation of a wheel and detecting a stride by the user;
determining the position of the user based on the relative change in direction input from the user and the distance traversed by the user; and
displaying the position of the user via the graphical user interface.

Abstract
A system for determining a position of a user. The system includes a distance sensor in communication with a position tracking device. The distance sensor is for detecting movement by the user, and the position tracking device is for determining the position of the user based on detection of movement by the user and a relative change in direction input from the user.

2. A method for determining a position of a user, comprising:
-
receiving a relative change in direction input from the user via a graphical user interface;
determining a distance traversed by the user;
determining the position of the user based on the relative change in direction input from the user and the distance traversed by the user, wherein determining the position of the user includes determining the position of the user relative to a reference point based on the relative change in direction input from the user and the distance traversed by the user, wherein the reference point is selected from the group consisting of an initial reference point and a waypoint; and
displaying the position of the user via the graphical user interface.

3. A method for determining a position of a user, comprising:
-
receiving a relative change in direction input from the user via a graphical user interface;
determining a distance traversed by the user;
determining the position of the user based on the relative change in direction input from the user and the distance traversed by the user;
displaying the position of the user via the graphical user interface;
receiving a radio signal transmitted by a radio transmitter; and
determining a radio coverage pattern of the radio transmitter based on a strength of the received radio signal and the position of the user.

4. A system for determining a position of a user, comprising:
-
a distance sensor for detecting stride movement by the user based on rotation of a wheel pushed by the user; and
a position tracking device in communication with the distance sensor for determining the position of the user based on detection of stride movement by the user and a relative change in direction input from the user. - View Dependent Claims (5, 6, 7, 8, 9, 10)
