Applications Critique Applications Critique • Spatial Browsing • Are there any overlooked • Follow-me Audio/Video applications? • Novel User Interfaces • Are there undesirable • 3-D Mice applications? • Virtual Buttons • Augmented Reality • Do these applications require • Data creation, storage, and precise (3-cm) location retrieval tracking? • Personalization • Journaling 13 System Software: World System Software: World Model Model 14 7

System Software Critique System Software Critique • Depends on hardware infrastructure – would not work “ad-hoc” • Assumes a single coordinate system • Assumes an accurate, invariant world model • Scales only to a point • Centralized database for low latency 16 8

Discussion Questions Discussion Questions [Gaetano] [Gaetano] 1. When is the right place for intentional or implicit interaction? 2. When using implicit interaction, how can users recover when the system makes the wrong association? 3. How do different associations that applications might want overlay with each other? 4. What requirements are placed on the resolution of the location system by different applications? 5. How can these requirements be relaxed using other sensed information besides location? 6. Would an arbitrary resolution location system solve all the problems, if not, which stay with us? 17 9
