- 1 Intro
- 2 Applications
- 3 Limitations of Past Work
- 4 How do these systems work?
- 5 FMCW: Measure time by measuring frequency
- 6 Mapping Distance to Location
- 7 Dealing with multi-path is easy when there is one moving user
- 8 Combining across multiple vantage points Experiment: Two users walking
- 9 Achieving 16 vantage points • Naive solution: 1 Transmitter and 16 Receivers
- 10 Ideally: Transmit in the same time and in the same frequency band without interfering
- 11 Objective: Transmit and Get Reflection
- 12 Multi-shift FMCW enables multiple transmissions at the same time and in the same frequency band without interference
- 13 Exploit breathing motion for localize static users
- 14 User Sitting Still (Breathing)
- 15 Implementation
- 16 Accuracy of Localizing Static Users 100 experiments where users sit down in different locations in the room
- 17 Reflection-based Human Localization
