2. 2 SDP 12 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. 3 SDP 12 Goals  Redefine presentations  Ease of transition between slides  Display more information  Minimize computer interactions  Present anywhere on any surface

4. 4 SDP 12 Bright Project on different surfaces

5. 5 SDP 12 Microsoft Kinect Point cloud depth information Spatial gesture information Sound recognition

6. 6 SDP 12 Kinect demonstration  Its time for!!! DEMO TIMEEE!!!  Be Amazed at this Demo!  Now say, oohhhh ahhh.

7. 7 SDP 12 Design Specifications –Block Diagram Block Diagram Component Interface

8. 8 SDP 12 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. 9 SDP 12 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. 10 SDP 12 Design Specifications – Software (cont’d) Kinect  Start/End Presentation  Change Slides Backward, Forward, Split  Invoke menu Context menus Application menus

11. 11 SDP 12 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. 12 SDP 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. 13 SDP 12 Midway Design Review (cont’d)  Projected costs DAC ~ $15.60 Green Laser ~ $32.50 Galvanometer set ~220 Total Costs: $275 (with tax & shipping)
