6 RESULTS AND CONCLUSIONS

We have succeeded through design and testing in providing a very useful surroundings

awareness panel that displays accurate data to the user in an easy to interpret manner. Through

testing, the current distance panel was proven to provide faster run times, with fewer collisions

than any of the other methods we had seen in prior studies.

We succeeded in providing proof that the guidelines we followed in the creation of the interface

were accurate assumptions. These guidelines and the results of the experiments are summarized

in table 4.

• We provided a map of where the robot had been. Although we had many complaints

about our map, we found in the usability study performed on version 2.0 that a good

map is liked and wanted by users. Also, as a result, we say that not only should the

interface provide a map of where the robot has been, but also should provide the

functionality to be able to place labels and landmarks on the map.

• We fused sensor information to lower the cognitive load on user. Having the laser and

sonar sensor values being displayed in the same distance panel allowed the users to only

have to look at one spot on the interface for the distance information. Through an

iterative process, we successfully provided a way to provide more spatial information

about the robot in the environment in an easy to interpret distance panel. The display

panel rotates when the operator pans the camera. This allows the user to line up the

obstacle they see in the video with where it is represented in the distance panel, which

also reduces their cognitive load.

• We also provide indicators of robot health and state. We include information on which

camera is currently in the main display. Crosshairs are overlaid on the video screen to

show the current pan/tilt position of the main camera. The rotation of the distance

panel also doubles as a pan indicator.

• We have shown, in the second experiment of version 1.0, that the ability to see the

robot’s chassis improves SA. This finding helps to strengthen the guideline that states

the robot should have the ability to self inspect its body for damage or entangled

obstacles.
