Terrain reasoning for human locomotion

We describe a real-time model of terrain traversal by simulated human agents. Agent navigations includes a variety of simulated sensors, terrain reasoning with behavioral constraints, and detailed simulation of a variety of locomotion techniques. The path through the terrain is incrementally computed by a behavioral reasoning system configuring a behavioral feedback network. A number of sensors...

Dynamic Context Maintenance in Human Terrain

Recent armed conflicts highlight the military’s need to develop new strategies that assist in situational assessment and planning for combating insurgent operations. Although insurgent warfare tactics have been used for thousands of years, the degree to which they have been recently employed presents an especially significant challenge. One of the challenges the intelligence community faces in ...

The Untold Story of the Human Terrain System

Human Terrain: A Tactical Issue or a Strategic C4I Problem?

The term “human terrain” was coined recently by the Army in response to critical needs for information about the individuals, groups and the workings of the society in general in Iraq. The call for help and the response to date has focused on tactical operations, but it is essential to consider the possibility that the tactical need points to a strategic issue for the C4ISR community. In this p...

Human response to buffeting in an all-terrain vehicle.

Suitably prepared subjects were exposed to the vibration imposed by driving a personal-type all-terrain vehicle over a heavily plowed track. Acceleration was measured in the Z-axis at the seat of the vehicle, and in the X, Y, and Z axes at the hip and head of the subjects. Acceleration peaks, rates of onset, durations, and frequency ranges were determined and a spectral analysis conducted. Resu...
