U.K. researchers talk up virtual reality

Computing experts at Cardiff University, England, are developing a realistic animation system that simulates the movements of a face, based on speech. The team in the school of computer science has developed highly advanced software, which is continually learning the facial dynamics associated with a speaker and applying this knowledge to synthesize realistic facial animations.

"Our aim is to create sophisticated facial animation through speech," explains David Marshall, PhD. "The applications include a new sophistication in film, computer graphics and animation technology  not just for films and games, but also for educational, mobile telecommunications, advertising, information services and internet applications."

The team has now become the first to invest in the latest video camera technology from U.S. company 3dMD, Atlanta. This latest generation "4-D system" is the first commercially available product that combines the element of time with the rapid generation of medically accurate 3-D surface models.

"We had exhausted the possibilities of 2-D technology," says Marshall. "The new camera enables us to capture high quality data at very high speed and will provide the next level of detail to reproduce expressions and the subtle nuances that happen during speech."
