  1. Proseminar: Anwendungen für Augmented Reality Application in Teaching: The Luminous Room Xinxing Feng July.05.2005

  2. Outline • Introduction • Example Applications • Illuminating Light • Distributed Illuminating Light • Urp(with Seep) • Getting Pixels in and out • Display • Capture • I/O Bulb • Luminous Room Vision Techniques • Seeing Spots • Software Support: glimpser • Toolkits: voodoo and dee-voodoo • Conclusion Proseminar AR: The Luminous Room

  3. Introduction • The Luminous Room wasbuilt by Tangible Media Group of the MIT Media Laboratory • I/O Bulb two-way information: • a projector • a video camera Proseminar AR: The Luminous Room

  4. Outline • Introduction • Example Applications • Illuminating Light • Distributed Illuminating Light • Urp(with Seep) • Getting Pixels in and out • Display • Capture • I/O Bulb • Luminous Room Vision Techniques • Seeing Spots • Software Support: glimpser • Toolkits: voodoo and dee-voodoo • Conclusion Proseminar AR: The Luminous Room

  5. 1. Illuminating Light • Designed as a effective tool for optical engineers Proseminar AR: The Luminous Room

  6. 1. Illuminating Light(cont.) • Holography hologram-recording layout simulation physical optics & digital light beams Video Proseminar AR: The Luminous Room

  7. 2. Distributed Illuminating Light • Distribution scheme • The toolkit dee-voodoo • Two modes of distributed operation • Each workspace is a “window” onto a continuous optics workbench. • “I-see-what-you-see”. All workspaces are instances of the same underlying space. Video Proseminar AR: The Luminous Room

  8. 3. Urp • A system for urban planning (Stadtplanung) • shadows of buildings • sunlight reflection from the glassface of the buildings Proseminar AR: The Luminous Room

  9. 3. Urp (cont.) • Measurement • Wind simulation based on Seep The direction and length of those segments correspond to instant direction and intensity of the wind at the position. Video Proseminar AR: The Luminous Room

  10. Outline • Introduction • Example Applications • Illuminating Light • Distributed Illuminating Light • Urp(with Seep) • Getting Pixels in and out • Display • Capture • I/O Bulb • Luminous Room Vision Techniques • Seeing Spots • Software Support: glimpser • Toolkits: voodoo and dee-voodoo • Conclusion Proseminar AR: The Luminous Room

  11. Display & Capture • Three basic ways to enable display at an architectural surface: • hoary CRT, flat-panel display • projection • E-ink • Basic schemes for capture and spatial tracking: • tethered tagging scheme • electronic non-contact tagless scheme • optical non-contact tagless scheme • electronic non-contact tagging scheme Proseminar AR: The Luminous Room

  12. I/O Bulb • Scheme: camera-in and projector-out I/O Bulb Prototype Proseminar AR: The Luminous Room

  13. I/O Bulb (cont.) • Different size of I/O Bulbs: Fixed conference table system Ceiling-mounted gimbal (Kardanring) Desk lamp system large scale small scale medium scale Proseminar AR: The Luminous Room

  14. Outline • Introduction • Example Applications • Illuminating Light • Distributed Illuminating Light • Urp(with Seep) • Getting Pixels in and out • Display • Capture • I/O Bulb • Luminous Room Vision Techniques • Seeing Spots • Software Support: glimpser • Toolkits: voodoo and dee-voodoo • Conclusion Proseminar AR: The Luminous Room

  15. See Spots • Object-independent tagging scheme • Reliable isolation from unpredictable background. Dots self-luminous?LEDs? • Maxim: objects used by Luminous Room applications should be passive. • Retroreflective dots: 3M ScotchLite Proseminar AR: The Luminous Room

  16. Outline • Introduction • Example Applications • Illuminating Light • Distributed Illuminating Light • Urp(with Seep) • Getting Pixels in and out • Display • Capture • I/O Bulb • Luminous Room Vision Techniques • Seeing Spots • Software Support: glimpser • Toolkits: voodoo and dee-voodoo • Conclusion Proseminar AR: The Luminous Room

  17. Software Support: glimpser • low-level vision technique: identifies colored dots in its input • finder: locate a specific-sized region of some particular color. Proseminar AR: The Luminous Room

  18. Geometric parsing toolkit: voodoo • voodoo analyzes each unorganized per-frame collection of color dots into a list of unique patterns. • Two parameters:1. the distance between each pair of dots 2. the angle through each triplet, along with the dots’ color sequence Proseminar AR: The Luminous Room

  19. Toolkit: dee-voodoo I/OBulbA I/OBulbB -------TCP/IP-------- dee-voodoo dee-voodoo Proseminar AR: The Luminous Room

  20. Conclusion • the Luminous Room • Getting Pixels in and out: Display & Capture, I/O Bulb • Luminous Room Vision Techniques : color-dot patterns • Software Support: glimpser, toolkits: voodoo and dee-voodoo • Example Applications: Illuminating Light, Distributed Illuminating Light, Urp • future improvements • Increasing the resolution of the I/O Bulb • Minimizing the ambiguity of the real and virtual objects • Extension to 3D Proseminar AR: The Luminous Room
