9 Ranging by Sound Motivation Problem Design Evaluation Conclusion

10 Not Suitable for MMG （ assume the maximum speed of a player ‘ s hand is 2m/s ） Motivation Problem Design Evaluation Conclusion

11 Distance Measurement in MMG • No infrastructure support, commodity phones • Real-time measurement – Low measurement time: <=100ms – High measurement frequency: > 10 times/second • Accurate – Centimeter level accuracy • Robust – Mobility: Up to 4m/s hand-to-hand speed – Environment noise: talking, laughing, shouting, walls, … Motivation Problem Design Evaluation Conclusion

12 Contributions enable real time distance measurement employ a new pipelined streaming executio n strategy understand and tackle the practical sources of measurement error during motion gamin g for increased robustness Motivation Problem Design Evaluation Conclusion
