Visual Analytics of User Behavior

• Project Description:

Analyze and predict user behavior in a virtual world to inform dynamic modifications to the environment to create a richer virtual experience.

• Major Accomplishments:– Identified virtual environmental differences that affect the user’s

exploration affinity level– Extended game engine technology with visualization toolset to represent

user position, velocity, time, map coverage, interaction events– Utilized deterministic nature of the engine to mine additional data of

interest after original play session

• Image Analysis– Techniques have been refined– Need real time image analysis to drive a

feedback loop back into the system• Integrate image analysis techniques in real time

with the virtual world system

• Virtual world behavior driven by analysis– Real-time analysis will customize and enhance

experience on a per-user basis– Integrate analytics framework into virtual world engine– Categorize user on the fly

• Timid• Speedy• Immersed

– Loading based on Navigation prediction• Preload assets based on paths users typically take at

certain decision points.
