The Main Point The Main Point

• Top down question:
• How do we make environments sentient?
• Bottom up question:
• What can be done with an accurate indoor location

system?

Applications Critique Applications Critique

• Spatial Browsing
• Follow-me Audio/Video
• Novel User Interfaces
• 3-D Mice
• Virtual Buttons
• Augmented Reality
• Data creation, storage, and

retrieval

• Personalization
• Journaling
• Are there any overlooked

applications?

• Are there undesirable

applications?

• Do these applications require

precise (3-cm) location tracking?

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

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
• verlay 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?
