When switching from looking around the environment to driving the robot, operators often

forget to change the camera view [Yanco et al., 2004]. One option to correct this problem would

be to automatically center the camera when the operator starts driving. However, there might be

times where an operator would like to look along a wall to the left while moving forward. In this

case, we would like to allow the camera to remain pointing to the left. Instead of making an

automatic adjustment, we choose instead to make a more visible reminder of the camera’s

orientation. Rather than having separate indicators for the pan and tilt of the robot's camera, as

seen in other systems such as the original INL interface (seen in figure 2), we overlay a small

cross on the screen to indicate the direction in which the camera is pointing. These crosshairs

were inspired by the older Brno robot system, as seen in figure 8.

In the prior studies discussed by Yanco, Drury and Scholtz [2004], it was observed that the
