New virtual reality array allows immersive experience without the disorienting 3-D goggles

13.05.2003


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. The system will be demonstrated for journalists and others Thursday, May 15.



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.

"Traditional virtual reality experiences offer limited simulations and interactions through tracking of a few sensors mounted on the body," said Norman I. Badler, professor of computer and information science and director of Penn’s Center for Human Modeling and Simulation. "LiveActor permits whole-body tracking and doesn’t require clunky 3-D goggles, resulting in a more realistic experience."


LiveActor users wear a special suit that positions 30 sensors on different parts of the body. As the system tracks the movement of these sensors as an actor moves around a stage roughly 10 feet by 20 feet in size, a virtual character -- such as a dancing, computer-generated Ben Franklin, Penn’s founder -- can recreate the user’s movements with great precision and without a noticeable time lag. The system can also project images onto the array of screens surrounding the LiveActor stage, allowing users to interact with a bevy of virtual environments.

LiveActor’s creators envision an array of applications and plan to make the system available to companies and researchers. Undergraduates have already used LiveActor to create a startlingly realistic but completely imaginary 3-D chapel. The array could be used to generate footage of virtual characters in movies, sidestepping arduous frame-by-frame drawing. LiveActor could also help those with post-traumatic stress disorder face their fears in a comfortable, controlled environment.

"The system is much more than the sum of its parts," Badler said. "Motion capture has traditionally been used for animation, game development and human performance analysis, but with LiveActor users can delve deeper into virtual worlds. The system affords a richer set of interactions with both characters and objects in the virtual environment."

While stereo projection systems have in the past been limited to relatively static observation and navigation -- such as architectural walk-throughs, games and medical visualizations -- LiveActor can be used to simulate nearly any environment or circumstance, chart user reactions and train users to behave in new ways. Unlike actual humans, virtual characters can be scripted to behave consistently in a certain way.


LiveActor was made possible through a grant from the National Science Foundation with matching funding by Penn’s School of Engineering and Applied Science, as well as equipment grants from Ascension Technology Corporation and EON Reality.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
