Many future military operations are expected to occur in urban environments. 
These complex, 3D battlefields introduce many challenges to the dismounted 
warfighter.  Better situational awareness is required for effective operation in 
urban environments.  However, delivering this information to the dismounted 
warfighter is extremely difficult.  For example, maps draw a user's attention 
away from the environment and cannot directly represent the three-dimensional 
nature of the terrain. 
To overcome these difficulties, we are developing the Battlefield Augmented 
Reality System (BARS).  The system consists of a wearable computer, a wireless 
network system, and a tracked see-through head-mounted display (HMD).  The 
computer generates graphics that, from the user's perspective, appear to be 
aligned with the actual environment.  For example, a building could be augmented 
to show its name, a plan of its interior, icons to represent reported sniper 
locations, and the names of adjacent streets. 
This paper surveys the current state of development of BARS and describes 
ongoing research efforts.  We describe four major research areas.  The first is 
the development of an effective, efficient user interface for displaying data 
and processing user inputs.  The second is the capability for collaboration 
between multiple BARS users and other systems.  Third, we describe the current 
hardware for both a mobile and indoor prototype system.  Finally, we describe 
initial efforts to formally evaluate the capabilities of the system from a 
user's perspective through scenario analysis.  We also will discuss the use of 
the BARS system in STRICOM's Embedded Training initiative.
