Abstract:
A portable communications receiver includes a receiver for receiving and detecting periodically transmitted selective call paging signals and data signals. In response to the selective call paging signal, a decoder generates control signals which allow storage of the data signals in a memory, and a display of the latest stored signals. A graphic characterization is provided for depicting the moving object. The effect of movement of the object is generated as the data signals are periodically updated and displayed. By individually animating the graphic characterization between updates, the effect of movement is enhanced. The data signals are periodically updated and include an absolute position signal for depicting an absolute position of the moving object. The data signals further include a relative position signal for depicting a relative position of the moving object relative to another moving object.
