  1. Team Mosaic Project “PRASER” Senior Design Project 2012 Advisor: Professor Lixin Gao Members: Allen Chew, Charles Essien, Brian Giang, Simon Ma Evaluators: Professor Frasier, Professor Gong

  2. Agenda • Introduction • Praser – The laser presentation experience • Goals • Background comparison • Design Specifications • System Block Diagram • Laser System • Software Systems • MDR • Distribution of tasks / Team responsibility • Proposed Prototype concept • Internal deadlines

  3. Goals • Redefine presentations • Ease of transition between slides • Display more information • Minimize computer interactions • Present anywhere on any surface

  4. Lasers • Bright • Project on different surfaces Keystone

  5. Microsoft Kinect • Point cloud depth information • Spatial gesture information • Sound recognition

  6. Kinect demonstration • Its time for!!! DEMO TIMEEE!!! • Be Amazed at this Demo! • Now say, oohhhh ahhh.

  7. Design Specifications –Block Diagram Block Diagram Component Interface

  8. Design Specifications –Laser System • Four major components: Galvo, DAC, Laser Pointer, Power Supply • Laser - create each pixel of the projection • Galvanometer - reflect the laser on x & y axis • Digital to Analog Converter - communication between the computer and galvo • Power Supply – The power supply will power the laser and galvanometer

  9. Design Specifications – Software • Interface between computer and Kinect • Implement Kinect SDK Motion capture and gesture recognition • Primary coding language: C++ • Head avoidance and Canvas Calibration

  10. Design Specifications – Software (cont’d) Kinect • Start/End Presentation • Change Slides • Backward , Forward, Split • Invoke menu • Context menus • Application menus

  11. Midway Design Review - Team Responsibility Allen Chew (CSE) – Laser simulation coordinator, PowerPoint control, rendering Charles Essien (CSE) – Gesture recognition, PowerPoint control Brian Giang (EE) – Laser projection coordinator, team manager Simon Ma (CSE) – Laser projection hardware, rendering

  12. Midway Design Review • Initial design and prototype • A working laser system that will project onto any surface • Computer interfacing with the Kinects • Controlling the laser with a computer input to draw basic shapes

  13. Midway Design Review (cont’d) • Projected costs • DAC ~ $15.60 • Green Laser ~ $32.50 • Galvanometer set ~220 • Total Costs:$275 (with tax & shipping)

  14. MDR - Internal deadlines • October 21, 2011 • Laser simulation • Kinect SDK • October 28, 2011 • Gestural interface • November 4, 2011 • Complete laser system • Power point control • November 17, 2011 • Display basic shapes • MDR – November 28-30

  15. MDR - Internal deadlines • MDR – November 28-30

  16. Design Specifications -Hardware • Kinect Specification • 30Hz 8-bit VGA resolution (640 × 480 pixels) • Usable distance 3.9 ft – 11 ft • Angular FOV 57° horizontally and 43° vertically • motorized tilting up to 27° • minimum viewing horizontal distance of 34 in • minimum viewing vertical 63 cm • microphone array features four microphone capsules

  17. Applications • Useful Widgets and Tools • Graph • Ruler • Clock • Timer • Android Application • Draw or Type on top of presentation in real time • Music • Collaborative creative environments • Laser Keyboard/Harp • Avatar Presentation • Display pretty avatars for presentations.

  18. Requirements • Hardware • A laser projector capable of displaying images and text • Software • Gestural recognition from the Kinect sensor • Avoidance system • Interactive menu system
