Transcript of CS6360 – Virtual Reality
Computing Paradigms
• What is the overall computing theme for– Windows GUI– Unix– Google docs
• VR?
Virtual Reality Goal• Take human senses
– Sight– Sound– Touch– Taste– Smell– Proprioception
• Replace them with computer generated data• Create sense of immersion
Lawnmower Man start at 2:38
Virtual Reality Research• Improving the quality of computer generated worlds
through better– Tracking
• Accuracy• Latency
– Real-time computer graphics– Displays (HMD, tiled wall, etc)– Sound rendering– Collision and response– Force feedback
• Finding new ways for people to interact with these worlds– Interfaces for 3D (GUIs)– Devices
Course Topics
• Virtual Reality– Using VR equipment– Mathematical background– Software background– Simulation– Graphics– Historical development– Human factors
My Interests
• Geometric algorithms and their applications
• Dissertation on force-feedback interfaces– Leads to a larger interest in VR
• Recent problem areas are symbolic solvers, path planning, and algorithms for biology.
