1. Advised by Prof. Pedro V. Sander By LEE Ning Hin Lincoln, LOU Yu Hong, WU Kam Kong

2.  Motivation  Primary Goal  System Overview  System Components ◦ Graphics ◦ Network ◦ User Interface  Problems Encountered  Future Developments  Q&A

3.  High resolution world ◦ High definition technologies ◦ Gigapixel images ◦ Result = ?  Cheaper sensors ◦ Touch-based ◦ Motion-based ◦ Location-based ◦ Result = ?

4.  Multi-display array ◦ Multiple monitors to form a single high resolution display unit ◦ Synchronized images  Gigapixel image ◦ One billion pixels  Wiimote ◦ Creative and user-friendly interface

9.  Image name  Two points coordinate #image_name#x1#y1#x2#y2#

10.  Version 2.0  WSADATA

11.  Sample size for each test: 1000

12.  OpenGL ◦ Displaying the image  SDL ◦ Window Management  DevIL ◦ Image loading

13. 1. SDL window initialize 2. DevIL decode jpg image 3. OpenGL display texture

14.  Create window  Create OpenGL context  Handle keyboard event

15.  Load image file  Decode image file  Pass data to OpenGL texture

16.  Set up environment  Create coordinate system  Draw a rectangle  Paste texture on it

17.  Split the image file into tiles  Draw multiple quads  Paste different texture on them

25.  Traditional ◦ Key mapping ◦ Infrared tracking ◦ Distance measuring ◦ Haptic feedback  Reverse traditional ◦ No buttons ◦ Infrared tracking (Another approach)

26.  Throughput ◦ Lots of data  Accuracy ◦ Errors in infrared tracking  Sensitivity

27.  Management of workstations ◦ Remote control ◦ Classroom management ◦ Wake on LAN ◦ Network Boot ◦ Shared drive

28.  Dynamic loading of texture ◦ Save memory but decrease in performance

29.  Synchronization ◦ Computer clock ◦ Internet time server

30.  Other User Interface ◦ 3D camera ◦ Touch-based devices  Other Wiimote usages ◦ Two infrared LEDs tracking for zooming in Wiimote ◦ With a mirrored infrared source
