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

2 05.July.2005Proseminar AR: The Luminous Room2 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

3 05.July.2005Proseminar AR: The Luminous Room3 Introduction The Luminous Room was built by Tangible Media Group of the MIT Media Laboratory I/O Bulb two-way information: a projector a video camera

4 05.July.2005Proseminar AR: The Luminous Room4 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

5 05.July.2005Proseminar AR: The Luminous Room5 1. Illuminating Light Designed as a effective tool for optical engineers

6 05.July.2005Proseminar AR: The Luminous Room6 1. Illuminating Light (cont.) Holography hologram-recording layout simulation physical optics & digital light beams Video

7 05.July.2005Proseminar AR: The Luminous Room7 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

8 05.July.2005Proseminar AR: The Luminous Room8 3. Urp A system for urban planning (Stadtplanung) shadows of buildings sunlight reflection from the glassface of the buildings

9 05.July.2005Proseminar AR: The Luminous Room9 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

10 05.July.2005Proseminar AR: The Luminous Room10 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

11 05.July.2005Proseminar AR: The Luminous Room11 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

12 05.July.2005Proseminar AR: The Luminous Room12 I/O Bulb Scheme: camera-in and projector-out I/O Bulb Prototype

13 05.July.2005Proseminar AR: The Luminous Room13 I/O Bulb (cont.) Different size of I/O Bulbs: large scalesmall scalemedium scale Ceiling-mounted gimbal (Kardanring) Desk lamp system Fixed conference table system

14 05.July.2005Proseminar AR: The Luminous Room14 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

15 05.July.2005Proseminar AR: The Luminous Room15 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

16 05.July.2005Proseminar AR: The Luminous Room16 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

17 05.July.2005Proseminar AR: The Luminous Room17 Software Support: glimpser low-level vision technique: identifies colored dots in its input finder: locate a specific-sized region of some particular color.

18 05.July.2005Proseminar AR: The Luminous Room18 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

19 05.July.2005Proseminar AR: The Luminous Room19 Toolkit: dee-voodoo I/O Bulb A I/O Bulb B dee-voodoo TCP/IP

20 05.July.2005Proseminar AR: The Luminous Room20 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
