An agent based approach to adaptive navigational support within 3D-environments

This paper investigates mechanisms and approaches
to assisting user navigation and exploration within 3-dimensional
wurlds. Specifically it advocates the deployment of an agentbased
approach to dynamic system assistance and intervention.
A performance equation is presented in a basic and an extended
version, which is used to activate system interventions and tu
evaluate user performances online and offline. The measure is
derived via a light-weight computationally inexpensive masking
approach. We describe some navigation experiments and the
results of navigational intervention via the damping of the
sensitivity of the navigational keys. Interestingly the navigational
assistance does not yield improvements in the subjects’ navigational
abilities.
