1. Overview Online ballet dictionary and syllabus: –Dance 66: Ballet Fundamentals –Dance 68: Ballet I –how it has been used as a learning resource outside the classroom Three dimensional dance archiving technology –explanation of its potential uses; –progress to date Incorporation of interactive dance technology into ECE Design Class projects –ECE 51: Microelectronic Circuit Design

2. 3-D dance archiving technology Would like to capture live dance –Review by students –Dance Archives Interactive 3-D models

7. Proposed Dance Archiving System Augmented Camera –Open source camera only system –Add thin wireless inertial sensors + active markers Credit: http://www.zingbeauty.com/dance.html

8. progress to date Masters Students have built a prototype inertial sensor:

9. Undergraduate research Applying inertial sensors to body tracking

10. Plans Seeking students to work on open source software camera motion capture project MS students working on the 3-D inertial tracker refinements Integration of camera motion capture and inertial tracker: – software development required

12. Incorporation of interactive dance technology Design Classes ECE 51: Microelectronic Circuit Design

13. ECE 51 First devices and circuits class for Electrical and Computer Engineering majors Small teams design / build / test circuits Semester long projects –Interactive Dance projects –Canes / floor / chairs Use video to “teach” –circuit design and fabrication –individual and team labs

14. Formed Groups 14 groups 3-4 students each Equally divided canes; floor; chairs

15. Canes Wireless canes Developed many sensors: – motion; touch; light;

16. Floors Students had to develop technology for low cost floor sensors –Paper capacitors; plastic foam resistors

17. Chairs Chairs were instrumented with motion and pressure sensors

18. Integrated Systems We used commercial software and MIDI interfaces to allow the dance devices to control real time video.

19. Video demos Chairman Mao Video Yes we Cane Video

20. Video Instruction for Labs Jing used for software design of circuits Webcam/digital camera used to record video MS movie maker editing Blackboard 8 used for display Also have videos on YouTube –Still experimenting with this

22. Issues Project course happiness bounce Video learning not enough alone

23. The Project course Happiness Bounce Survey Monkey Survey of Happieness

24. Plans for future Some of the interactive projects will be incorporated into a production “Chairman Mao” Chair is being worked on now.

25. Conclusions Video is a great tool for us for learning –Online Video Ballet Dictionary is working –Video Labs enable students to use more circuits Video is not enough –Students do not learn deeply from video –Needs reinforcing with repetition and feedback For dance need so much video that 3-D models may be only workable solution
