    [Border Collie Photo]

    [Border Collie Image] Border Collies such as these possess innate skills to move a flock of sheep. Notice how the dog stays back from the sheep while readjusting its angle of attack. Film courtesy of Evans Sumner.

    [User Herding Hoppers] We developed a virtual environment where the user plays the role of the Border Collie. The user rides a modified Tectrix bicycle to interact with a group of 15 simulated one-legged robots. The robots want to hop near one another, but hop away from the user. In this movie, the user is trying to herd the robot group into a corral.

    [Olympic Bike Race - 1996]

    [User Riding Bike Platform] A user can ride with simulated bicyclists along the streets of the 1996 Summer Olympic Race Course. The bike platform has an electric motor that tilts the platform +/- 12 degrees. The user can steer the bicycle +/- 20 degrees. A CompuTrainer Pro applies a load on the rear wheel to simulate hills.

    [User riding with bicyclists] This clip shows a user riding with a group of simulated bicyclists. The platform tilts to match the slope of the terrain and the rear wheel becomes harder to pedal as well.
