  1. Team Mosaic Project “PRASER” Senior Design Project Final Project Review Advisor: Professor LixinGao Members: Allen Chew, Charles Essien, Brian Giang, Simon Ma Evaluators: Professor Gong, Professor Vouvakis SDP 12

  2. Agenda • Introduction • Refined project definition • Comparison • Project Specification • System block diagram • Subsystem components • Application • Accomplished • Demonstration SDP 12 2

  3. Reintroduction - Motivation • Online presentations are boring • Difficult to view both presentation and presenter at the same time • Low quality slides (streaming video) • Loss of focus on presenter • Viewing remote presentations • Bad visual quality • Loss of expression SDP 12 3

  4. Comparison • For most presentations, • Difficult to capture both the presenter and Power Point at the same time • Requires a cameraman • However our prototype application • Capable of capture both the presenter and Power Point • Addition functions/gestures SDP 12 4

  5. Reintroduction - Goals We want to: • Improve presentation experience • More interactive • More entertaining • Rethink approach to capturing presentations • Bring focus back to the presenter • Facilitate “emotion” for remote presentation SDP 12 5

  6. Design Specification – Project Definition Praser is … “A redesigned platform capable of delivering an enhanced presentation experience, both for in person and remote viewers.” • More interactive utility for presenters • Better experience for viewers with avatars SDP 12 6

  7. Design Specifications –Block Diagram System Block Diagram SDP 12 7

  8. Design Specifications – Kinect Subsystem • OpenNI & NITE • Generate “users” • Return interpreted motions and gestures • OpenGL • Real-time image manipulation OpenNI NITE OpenGL SDP 12 8

  9. Kinect Subsystem - Capabilities • Gesture Recognition • Hand gestures for control • User poses • Tracking • Mapping user position to screen • Location based “selections” • Compositing • Background removal • Image manipulation SDP 12 9

  10. Kinect Subsystem – Avatar Application • Capture presenter in on screen avatar • Walk around and point modes • X, Y coordinates mapped with Kinect Depth information • Presenter avatar points mapped to actual points SDP 12 10

  11. Kinect Subsystem – Avatar Application cont’d Benefits: • More expression and emotion • Better interaction with slideshow slides • More efficient remote viewing of presentation SDP 12 11

  12. Accomplished • Hand Tracking • Hand Gestures • Video Recording • Layer Control – Presenter, Power Point Slides, Annotations • Selecting specific Power Point Slides • Displaying two slides at once – Splitting SDP 12 12

  13. Kinect Demonstration SDP 12 13

  14. The Future • Writing Recognition when annotating. • Capturing the presenter in 3-D using two Kinects. • Using the Kinect for other purposes (e.g. medical diagnostics and therapy) SDP 12 14

  15. Problems Addressed • Purchased safety goggles to prevent retinal damage • Blanking not currently implemented • For safety reasons decided would be best not to use the laser system in this project. • Memory Leak in software • Video Recording • Threading • Tracking and Scaling SDP 12 15

  16. Team Responsibility Allen Chew (CSE) – Team Manager, Coordinated laser projection system, Software Development, Researched on how to build correctional amplifier, Researched and ordered parts for project in a timely manner Charles Essien (CSE) – Software coordinator, Research graphics libraries, Isolated user pixels and overlay onto slides, Created Flow and Calibration, Split Screen Brian Giang (EE) – Laser Projection Coordinator, Coordinated team meetings and set deadlines, Assembled laser projection system and figured signal lines from DAC Simon Ma (CSE) – Compiled OpenLase Binaries, Ported code over to Ubuntu, Coordinated hand tracking and gestures, Created Annotations SDP 12 16

  17. The End Thank you very much for your time. I hope you enjoyed the presentation. Questions? SDP 12 17
