PHILADELPHIA, June 25 -- The University of Pennsylvania has installed a virtual reality system that allows a participant full-body interaction with a virtual environment without the hassle of bulky, dizzying 3-D glasses. SUITED UP: Models demonstrate the motion capture suit in front of the LiveActor screen. Key to the installation, dubbed LiveActor, is the pairing of an optical motion capture system to monitor the body's movements with a stereo projection system to immerse users in a virtual environment. The combination lets users interact with characters embedded within virtual worlds....Read full articleRelated content from Photonics MediaArticlesLiquid Crystal Optics Support High-Performance Compact VR DisplayVirtual reality (VR) and mixed reality (MR) devices are used to access applications in a growing number of fields, from entertainment to health care to manufacturing to tourism.
