Perceiving Errors in the Motions of Realistic Virtual Characters

Who and when?
Sophie Jörg, postdoctoral researcher in the Graphics Lab at the Robotics Institute at Carnegie Mellon University, is going to visit our University on Thursday, July 5th. Her talk will start at 4:30 pm in room C116.

Topic: Perceiving Errors in the Motions of Realistic Virtual Characters
Virtual characters are becoming increasingly common in movies, games, and virtual reality applications. Rapid advances in performance capture and rendering techniques have allowed for the creation of characters that appear very human-like. However, people are remarkably good in recognizing errors in human motion, and very subtle details, such as small delays, can be interpreted differently.

In this talk, I will present multiple experiments that investigate the perception of delays in the motions of realistic virtual characters. We developed a platform game that we used to analyse the consequences of controller latencies, that is, delays in the responsiveness of a player’s character. I will provide evidence that a quick responsiveness becomes essential for more challenging tasks.Furthermore, I will demonstrate the importance of correct finger animations and will show that 0.5s of delay in the finger motions can change the interpretation of a scene.

Vita:
Sophie Jörg is a postdoctoral researcher in the Graphics Lab at the Robotics Institute at Carnegie Mellon University. Her research interests are in computer graphics, specifically animation and perception. After studying Physics and Media Technology in Freiburg and Hamburg, she worked at the Fraunhofer Institute IAIS as a Junior Researcher in the Virtual Human project. She received her PhD from Trinity College Dublin, Ireland, in March 2011. During her PhD, she also conducted research as a visiting student at Carnegie Mellon University and as an intern at Disney Research, Pittsburgh. She will be joining the School of Computing at Clemson University as an assistant professor in August 2012.
