Thanks to the help and advice from the guys over at NUI Group (www.nuigroup.com) forums especially the wonderful information supplied by PeauProductions (http://peauproductions.blogspot.com/), I have embarked on a project to build my own Rear DI Multi Touch table. I will be posting photographs and the progress of the building of the table.
This is the Playstation 3 EYE camera that will be modified to become IR capable. For people residing in Singapore, this is the packaging for the correct version of the camera to get. You can buy this at any Sony Style shop locally. Do note that some local game shops sell the European version of which I am unsure whether it is “friendly” towards modification.
The Camera removed from its shell
The dismantled pieces:
The lens mount removed from the circuit board:
I think I did a pretty lousy job in removing the IR blocking filter from the rear of the lens mount, look at those jaggy edges:
This is the IR blocking filter removed. It was damaged when it was removed.
The visible light filter installed (cut out from floppy disk). This filter functions by blocking out visible light and letting infrared light through.
And this is my work desk where all the mess is. The top right corner is a wide angle (180 degrees) IR illuminator that I am using for the Rear DI set up.
Next I will be making the box to sit the small piece of acrylic I got from a local art and craft shop (12″ x 18″ x 3mm(T)). It is available at Art friends for all you Singaporeans out there and costs around $8 only. Great for testing and fiddling around. I will be running tests soon using tbeta once I find time and I will post the tracking results.
On a side note: I am also intending to build a DSI table which uses a special acrylic called Endlighten. If you are living in Singapore/Malaysia and are interested in getting a piece of this very hard to get acrylic please contact me and let me know. I have managed to find a local manufacturer who has kindly indented and offered to laser cut the standard sheet (120″ x 80″ to 10 pieces of 39″ x 22″ x 10mm(T)) at $200 USD per piece. There are 4 pieces left for reserve as of this posting.
I came across your youtube video demoing the finished product. Awesome stuff! Do write about the rest of the steps involved in building the working prototype.
When I was in uni, I did something similar to my webcam. I removed the IR filter from the webcam and used a TV remote (my IR source) to draw stuff on the screen. Very low-tech and ugly
Heh Harish, I will be posting the rest of the steps and photos to detail the build process. The road ahead would probably be installing sensors on the table but I haven’t really figured out what I could do with the sensors at the moment.
Cool stuff you did at the university! I think these days they use the wiimote and do the same thing you did years ago!
Hihi! Just wondering if the Endlighten is still available.. I am a newbie but I really really interested to do this at home.. Can you help me out a lil bit? I want to do a Rear DI using Endlighten..probably use reactivision to do fiducial tracking.. ^__^
Tired of getting low amounts of useless traffic for your site? Well i want to let you know about a new underground tactic which makes me personally $900 every day on 100% AUTOPILOT. I really could be here all day and going into detail but why dont you just check their website out? There is really a excellent video that explains everything. So if your serious about making simple cash this is the website for you. Auto Traffic Avalanche
