ABSTRACT:
Wireless communication terminals are disclosed that display the direction and distance between them so that users can, for example, travel away from each other and then later find one another. The terminals are configured to track their movement using acceleration data. Some of the terminals may operate as slave terminals in which they transmit their movement data to a master terminal which determines therefrom the relative direction and distance between the terminals. The master terminal may then transmit the relative direction and distance data to the slave terminals where it can be displayed to their users.
