Scenarios in Virtual Environments
Linzhen Nie and Ronald R. Mourant
Scenarios are situations that usually involve moving computer controlled (autonomous) objects. They are designed to cause a user to react.
A scenario can start by a user reaching a specific location. When that location is reached a "trigger" is fired and the scenario begins.
Scenarios are used to measure the skill level of the participant.
Here are some examples of scenarios.
An illegally parked vehicle. A pedestrian in the crosswalk.
A vehicle cutting in front of you. A bicycle about to cross the road.
When a scenario happens, we measure the driver's performance in terms of vehicle control (steering, braking, acceleration) and physiological measures (heart rate, galvanic skin response). Our eye-movement camera can be used to determine the point at which a driver detects a dangerous situation.
