nTalk Title: Scaling virtual worlds: research challenges and opportunities

Talk Abstract:
Virtual worlds (also referred as "distributed/network

ed virtual environments") use simulation to create a fully-immersive 3D spa

ce in which users interact and collaborate in real time. It is still a grea

t challenge to scale virtual worlds to provide rich user experiences, high
level of realism, and innovative usages. There are three unique simulatio

n requirements in scaling virtual worlds: (1) large-scale, real time and p

erpetual simulations with distributed interactions, (2) simultaneous visua

lization for many endpoints with unique perspectives, and (3) integration

of multiple simulation engines with different operation characteristics. In
this talk, we review the research challenges in meeting these requirement

s, present the scalability barriers we observed in current virtual world s

ystems, and discuss research opportunities in the fields of simulation, c

ommunication, and rendering.

Speaker Bio:
Huaiyu Liu received her P

h.D. in Computer Science from the University of Texas at Austin, under the
supervision of Dr. Lam, where her Ph.D. thesis work focused on designing

a resilient routing infrastructure for peer-to-peer networks. She joined In

tel Labs as a research scientist in 2005. While at Intel, she had worked o

n multi-radio networks and energy efficient wireless communications. Curren

tly she is a member of the Virtual World Infrastructure team under the Micr

oprocessor & Programming Research group. Her current research is to design

and develop scalable virtual world architectures and optimize virtual world
operations on heterogeneous hardware.
