The Virtual PWC Facility

Explore the innovative Virtual PWC Facility by Tony Andrady and Klaus-Peter Beier for symbolically depicted, futuristic environments indistinguishable from reality. The facility allows for the creation of a virtual presence with engaging subject engagement in engineering scenarios, emphasizing realism, accurate interfaces, and logical environments with physics and behavioral rules. With a CAVE environment offering a near 180-degree field of vision, dynamic simulators, and scriptable scenarios, the Virtual PWC Facility enables data acquisition and analysis for experimental design, operator training, and human risk factor studies in recreational boating. Join the live demonstration by Professor Peter Beier at the University of Michigan VR Lab to witness the technical capabilities firsthand and experience test rides in the virtual lake environments. This event showcases the flexibility of testing, validated user experiences, and the practical utility of the Virtual PWC Facility for regulators, designers, and skilled vessel operators. Lunch will be served after the demonstration.

  5. The Virtual“Presence” Symbolically Depicted Environments Environments sufficiently realistic to elicit typical and valid user responses. Futuristic Indistinguishable from Reality

  6. Creating a Virtual Presence CAVE Teleoperation “Presence” results in engagement of subject

  7. Engineering for “Presence” • Realism of Virtual content • An accurate physical interface • A good logical environment * physics rules * behavioral rules

  8. The CAVE Environment • Near 180 degree field of vision • Physics-based dynamics simulator • “Scriptability” of scenarios • Data Acquisition (throttle, handle bar, position, time, reaction time)
