Table 4: Original Guidelines and Results

Original Guideline Result Discussion

Revised or New Guideline (if

applicable)

Provide a map of

where the robot has

been.

Confirmed/

Revised

We proved that operators want to have a

map. Also, 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.

Provide a map of where the robot

has been, while providing the ability

to place labels and landmarks on the

map.

Fuse sensor

information to lower

the cognitive load on

user.

Supported

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. For

confirmation, another study to compare an

interface with similar distance panels

containing non-fused data with an interface

using the same panels with fused data

should be performed.

Provide more spatial

information about the

robot in the

environment.

Confirmed

Interface 3.0 provides a distance panel that

shows the user exactly how the robot is

situated within its local environment. This

panel was proven in the experiment to

provide increased situation awareness over

the other panels.

Provide a frame of

reference to determine

position of the robot

relative to its

environment.

Confirmed

The map and distance panel helped increase

situation awareness by providing a good

frame of reference to determine the position

of the robot relative to its environment.

Provide indicators of

robot health/state,

including which

camera is being used,

the position(s) of

camera(s), etc…

Supported

Although not explicitly tested, we observed

driving with the camera unknowingly not

centered was significantly less that was

noted in previous experiments. This is

assumed to be because of the crosshairs and

later the rotating distance panel.

The robot should

have the ability of the

robot to inspect its

body for damage or

entangled obstacles.

Confirmed

We have shown, in the second experiment

of version 1.0, that the ability to see the

robot’s chassis improves SA.

New

Users primarily pay attention to the video

screen, so keeping important information on

or near it makes it more noticeable.

Important information should be

presented on or very close to the

video screen.

New

We have shown in the second study of

interface version 1.0 that having a rear

facing camera significantly improves

situation awareness.

If the robot system has more than

one camera, a second camera should

be mounted facing the rear of the

robot to provide the best SA

New

ADR mode reduces the amount of hits that

occur while the robot is backing up.

If the robot system has more than

one camera, the system should

include an ADR mode to improve

SA and reduce the number of

collisions that occur while the robot

is backing up.
