The interface designed by Swarthmore College researchers, shown in figure 4, also has a video-

centric interface [Maxwell, Ward and Heckel, 2004]. The operator interface consists of a main

panel showing the view of the video camera. It has a unique feature where it overlays green bars

on the video which show 0.5m distances projected onto the ground plane. The bars always stay

pointing in the forward direction relative to the robot, even when the camera is panned to the

side. It also has pan-tilt-zoom indicators, the red bars, on the top and left of the video screen.

The width of the red bars indicates the zoom setting: a wider bar means a higher zoom setting. It

also displays the current sonar and infrared distance data, where white indicates open space.

This system performed well at the Association for the Advancement of Artificial Intelligence

(AAAI) robot competitions. This interface does a good job with some of the previously

mentioned guidelines. It provides a way to tell camera orientation, shows robot location by way

of a map and has a large video screen. It could be improved by showing how the robot fits in

the environment better by improving the sensor display at the bottom center of the screen.
