Virtual Exertions Physical Interactions in a Virtual Reality CAVE for Simulating Forceful Tasks Robert G. Radwin Karen B. Chen Kevin Ponto Ross D. Tredinnick Abstract This paper introduces the concept of virtual exertions, which utilizes real-time feedback from electromyograms (EMG), combined with tracked body movements, to simulate forceful exertions (e.g. lifting, […]
Manually Locating Physical and Virtual Reality Objects Karen B. Chen Ryan A. Kimmel Aaron Bartholomew Kevin Ponto Michael L. Gleicher Robert G. Radwin Abstract: Objective: In this study, we compared how users locate physical and equivalent three-dimensional images of virtual objects in a cave automatic virtual environment (CAVE) using the hand […]
Kevin Ponto, Michael Gleicher, Robert G. Radwin, and Hyun Joon Shin Abstract—The perception of objects, depth, and distance has been repeatedly shown to be divergent between virtual and physical environments. We hypothesize that many of these discrepancies stem from incorrect geometric viewing parameters, specifically that physical measurements of eye position […]
Online real-time presentation of virtual experiences for external viewers Kevin Ponto, Hyun Joon Shin, Joe Kohlmann, Michael Gleicher Abstract Externally observing the experience of a participant in a virtual environment is generally accomplished by viewing an egocentric perspective. Monitoring this view can often be difficult for others to watch due […]
Poster: Say it to see it: A speech based immersive model retrieval system Ross Tredinnick, Kevin Ponto Abstract Virtual spaces have proven to be a valuable means to visualize and inspect 3D environments. Unfortunately, adding objects to 3D scenes while inside of an immersive environment is often difficult as the […]
SculptUp: A Rapid, Immersive 3D Modeling Environment Kevin Ponto Ross Tredinnick Aaron Bartholomew Carrie Roy Dan Szafir Daniel Greenheck Joe Kohlmann Abstract: Modeling complex objects and effects in mainstream graphics applications is not an easy task. Typically it takes a user months or years of training to feasibly make compelling […]
Visual analytics of inherently noisy crowdsourced data on ultra high resolution displays Andrew Huynh, Kevin Ponto, Albert Yu-Min Lin, Falko Kuester Abstract The increasing prevalence of distributed human microtasking, crowdsourcing, has followed the exponential increase in data collection capabilities. The large scale and distributed nature of these microtasks produce overwhelming […]
