The
PackBots being used by the U.S. military in
Afghanistan and the urban search and rescue (USAR) robots that worked
the World
Trade Center site are just two recent examples of mobile robots moving
from the
laboratory to the field. What is
significant about these new applications is that they invariably
involve some
form of human-robot interaction (HRI) rather than the full robot
autonomy that
has motivated most prior research. Conducting
HRI research can be extremely difficult because
experimentation with physical robots is expensive and time consuming.
Few
roboticists have experience or interest in conducting human
experimentation
while researchers in human factors or human computer interaction often
lack
experience in programming robots or access to robotic platforms. In this paper we describe a high fidelity
open source simulation intended for HRI researchers of varying
backgrounds and
providing reference tasks and environments to facilitate collaboration
and
sharing of results. The architecture
and capabilities of the game engine-based USARsim simulation are
described. Its
use for HRI research is illustrated through case studies describing
experiments
in camera control for remote viewing and integrated display of attitude
information.

(2005) "Attentive
Navigation for Viewpoint Control in Virtual Environments". Human
Factors. 47(3): 630-643. Three-dimensional virtual
environments and teleoperation
activities
depend on the ability to position an egocentric viewpoint at meaningful
locations. Evidence from foundational research has led to the
development of control strategies that generally adopt an
all-or-nothing approach to guiding the viewer to useful
vistas. This work examines Attentive Navigation, a
technique for partially automating viewpoint control to promote a
supportive, yet unscripted exploration of virtual environment. A
collection of
three experiments was designed to assess the effectiveness of Attentive
Navigation versus commonly used Free Navigation techniques.
Results show that
this approach has promising consequences for improving object
recognition,
developing an understanding of the configuration of objects, and in
searching
for target objects.

Exploration" IEEE Transactions on Systems, Man and Cybernetics -
Part A: Systems and Humans 35(4): 513-522.
Human
judgment is an
integral part of the
teleoperation
process that is often heavily influenced by a single video feed
returned from
the remote environment. Poor camera
placement, narrow field-of-view and other camera properties can
significantly
impair the operator’s perceptual link to the environment, inviting
cognitive
mistakes and general disorientation. These
faults may be enhanced or muted, depending on the
camera mountings
and control opportunities that are at the disposal of the
operator.
These issues form the basis for two user
studies that assess the effectiveness of existing and potential
teleoperation
controls. Findings suggest that providing
a camera that is controlled independently from the orientation of the
vehicle
may yield significant benefits. Moreover, there is evidence to support
the use
of separate cameras for different navigational subtasks. Third,
the use of multiple cameras can also
be used to provide assistance without encroaching on the operator’s
desired
threshold for control.

Multi-Agent-Based Software Bridge for Interoperability between
Distributed Military and Commercial Gaming Simulation", Simulation,
80(12), 647-657. Rapid
advances in consumer
electronics have led to the anomaly that consumer off-the-shelf gaming hardware and software provide better
interactive graphics than military and other specialized systems costing orders of magnitude more. UTSAF
(Unreal Tournament Semi-Automated Force) is bridging software written to take advantage of the
power of gaming systems by allowing them to participate in distributed simulations with military
simulators. UTSAF illustrates the use of multiagent technology to flexibly interconnect otherwise
incompatible systems. This article describes an architectural approach for rapidly constructing middleware by
taking advantage of built-in capabilities for processing, communication, and interoperation that a
multiagent infrastructure provides. Several software agents based on Reusable Environment for
Task-Structured Intelligent Networked Agents (RETSINAs) are used to support interoperability between
military simulation nodes based on distributed interactive simulation and Unreal game simulators.
Using a multiagent system, UTSAF can be expanded to support several network environments and
interact with other agent-based software.
