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

3-D dance archiving technology

• Would like to capture live dance– Review by students– Dance Archives

• Interactive 3-D models

Technologies

– Camera + markers – state of the art– Inertial sensors + active markers– Camera alone

Technologies

• inertial sensors + active markers– intrusive and expensive

Technologies

• Camera alone – very new– $88,000– Single user– Special

Proposed Dance Archiving System

• Augmented Camera– Open source camera only system– Add thin wireless inertial sensors + active

markers

progress to date

• Masters Students have built a prototype inertial sensor:

Undergraduate research

Applying inertial sensors to body tracking

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

Incorporation of interactive dance technology Design Classes

• ECE 51: Microelectronic Circuit Design

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

Formed Groups

• 14 groups 3-4 students each

• Equally divided canes; floor; chairs

Canes

• Wireless canes• Developed many sensors:

– motion; touch; light;

Floors

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

Chairs

• Chairs were instrumented with motion and pressure sensors

Integrated Systems

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

Video demos

Chairman Mao Video

Yes we Cane Video

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

Blackboard Site

• Jing video:– https://courses.duke.edu/webapps/

Issues

• Project course happiness bounce• Video learning not enough alone

The Project course Happiness Bounce

• Survey Monkey Survey of Happieness

Plans for future

• Some of the interactive projects will be incorporated into a production

• “Chairman Mao” Chair is being worked on now.

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
