The Distributed Extensible Virtual Reality Laboratory


The Projectiles experiment

In this experiment two users must cooperate to hit a target using the cannon, One user may alter the angle of the cannon's barrel and the initial speed of the cannon ball. The target is obscured from this user's view by a large wall, which the cannon ball must clear. The other user is 'strapped' to the cannon ball, but may freely move around the cannonball to obtain different perspectives about it, while the ball (and the user) is (are) in flight.

The following screenshot shows each user's view within the VE. The larger window (on the left hand side) is the controlling user's viewpoint, they control the cannon. The smaller window of the right hand side displays the point of view of the second user (strapped to the cannonball). In this shot the user has a "bird's eye view" of the cannon ball. (Each user cannot see the display of the other).


The next screenshot displays the moving user's point of view as they follow its path from behind. The wire cage which encapsulates the experiment is provided to provide a frame of reference for the moving user, enabling them to more accurately judge their speed and direction of travel.
