[edit] Synopsis
[edit] Design Requirements
For the design, here's the requirements that we're looking for:
- it needed to be about 4' high and 5' across;
- it needed to be easily disasembled for transport;
- it had to be quick to assemble for use;
- it had to work well in a lighted room;
- and of course, it had to be cheap.
[edit] Parts List
- Table (Surface to mount on)
- Glass 3' 5 1/8" x 1' 4"
- edges as static image (picked up by IR but not projected)
- IR LEDs - Ordered 150 count of these
[edit] Resources to Acquire
- Surface to project onto:
- Vellum (also called drafting paper)
- projector (mirrored from distance, or mounted) (buy)
- custom lens to alter throw distance?
- cheap lenses? http://www.surplusshed.com/
- custom lens to alter throw distance?
- webcam (buy)
- power supply (6-8 amp) (buy or scrounge)
- framing (build)
- dedicated computer
[edit] Potential Finds
- Dedicated computer with firewire
- Webcam with firewire
- Projector with appropriate throw
- mirror math
- the bottom of the glass will be 3' from the ground(approx., give or take 2")
[edit] Progress
- As of April 21 all of the LED wiring is complete. Now building projector.
- We had soldering party during SCoW event on April 13, 2011.
- Using Acrylic, Nick were able to build channels for IR LEDs.
- The table surface is now somewhat stable, and more or less done, with just a little tweaking it will be usable.
- Complete testing the tracking software: TUIO (reacTIVision open source software) with normal webcam and flashlight.
Re-purposing IR LEDs from remote controls.We ended up buying new IR LEDs.
[edit] July 7, 2011
- Danny introduced us to petticoat material that was used as a projector screen, and it works really great for playing Motion Bubbles (webcam/flash game).
- What we like about the material:
- very light and cheap.
- Almost Transparent (This property is cool because we could make a holographic image in the middle of the hall way,)
- What we don't like about this material:
- Too transparent (The projection didn't stop at the petticoat material, but also to the wall behind it.)
- What we like about the material:
[edit] Next Steps
- Pressing LEDs agains the glass with some kind of foam materials
- Covering the bottom with plywood+veneer
- Frosting glass
- Frosting spray
- or Using Vellum
- Fit Projector
[edit] Using Petticoat Material as the Screen
- We plan on finding a way to diffuse the undesired effect by placing the screen on the hall way or placing non reflective materials such as velvet on the wall.
- Using edge lightning technique or a webcam, we might be able to turn this into a multitouch or multigestures interface
