3. One-line Comment This paper designed a wearable wireless sensor platform which is truly wearable, scalable, able to support to high –level interactivity in forming wireless networks for interactive dance performance.

4. Statement of the Problem How to develop a wearable wireless sensor platform for Interactive dance performance? KEY WORD: Wearable, Scalable, able to support high-level interactivity

5. Solution approach Why dance? Art based on human body movement. KEY WORD: Wearable, Scalable, able to support high-level interactivity

6. This paper present design details of wearable wireless sensor platform and applied to an actual interactive dance performance, titled Dreams in the Forbidden City.

7. Platform Design • Wearable wireless sensor platform consists of three parts: • 3 Parts: • wearable wireless sensor nodes, wireless data aggregators • ,wireless interface boards

9. Wearable Wireless Sensor Node- Eco • An ultra-compact low-power wireless sensor node for real-time motion monitoring • 2. Currently the world’s smallest wireless sensor node in operation • it measures 12 × 12 mm2 in surface area, ×4.5mm thick (or 648mm3 in volume) and weighs 1.3 grams without the battery • the original design of Eco has only one two-axial accelerometer (ADXL202E) and a 125mAh Li-Coin battery (CR1632 [17]) • Modified the hardware: a three-axial accelerometer, temperature sensor, image sensor, light sensor, gyroscope, joint angle sensor, and heartbeat detector • Changed the Li-Coin battery to a 40mAh Li-Polymer battery (12 × 10× 3 mm3), which is able to power Eco for more than one hour

13. Platform Design – Scalability

14. Application Example How this platform can be applied to an actual interactive dance performance? ‘Dreams in the Forbidden City ‘ at UC Irvine in May 2005

15. Conclusion • This platform consists of wearable wireless sensor nodes, data aggregators, and wireless interface boards. • The distinguishing features of our platform are truly wear • able, highly scalable, multi-modal sensing, and seamless interface capabilities. • Choreographing interactive dance performances • that take full advantage of our platform. • Future work • At least tens of dancers will be performing together • 2. The dancers’ heartbeats and body temperatures will be monitored and beats to reflect the dancers’ conditions on the stage equipment.

16. Strong Point • The effectiveness of this platform by showing improvements to an actual interactive dance performance. • (Great: good application about Interactive) • Potential to related human body or any movement. • Entertainment Technology: Night Club ! • Stage Technology: Musical, Concert and so on.

17. Weak Point • Problem- Solution: Focused Wearable • Not sure solution: Scalable, High interactivity • 2. A fundamental limitation is to associate the motion data • with the dancers’ identities. • 3. Its support for interactivity is also limited, thereby impeding • the choreographer’s creativity • 4. Too much exercise for Dancer • 5. No originality
