Hello!
I am an industrial design student at Umeå institute of design making an interactive display to show the solar energy production of a building. I have some research done on the colors and graphic (check http://www.facebook.com/photo.php?pid=2065212&l=5acdaaceed&id=537776509) for reference.

I am now trying to produce a nice spherical display with near-ir interaction.

I want to usa a range sensor activated LED projector on a frosted glass surface. (As ambient “passive-mode” light i have some color programmed LED lights.)

So far I ordered bought these components:
Acer K10 - LED DLP-projector
6 x BlinkM MaxM - I2C Controlled RGB LED = £179.94
1 x Arduino Duemilanove (Updated 368 Version) = £20.58
2 x IR Range Sensor - Sharp GP2Y0A21YK = £18.50
2 x IR Range Sensor - Connector Cable = £3.30

For the IR part I plan to use:
webcam with out IR filter
IR-spotlight Kemo B223 (http://www.kjell.com/filarkiv/SUPPORTPDF/81-90/87/87223/b223.pdf)

Images:
First an normalized IR image from the A Multi-Touch Interactive Spherical Display from Microsoft http://www.youtube.com/watch?v=1aRQdiyNGGM&feature=player_embedded
but a bit more red (like I would like it). And then some process images.

Does anyone have any experience in using technology this technology on frosted glass? I have 5 weeks to the degree exhibition so I need all the help I can get!

Thank you,
Martin

Sounds like a great project. Looking forward to reading more about it.

Thank you!

I got bunch of the components today, but coolcomponents sent me the normal BlinkM LEDs not the new strong BlinkM MaxM that I ordered, now the email reply says We’re currently on annual leave. You may still place orders, and theywill be shipped when we return on the 12 April. And it’s sold out on al the US outlets! Ghaa, degree work stress!

Does any one have some to sell me?

Regards,

Martin

ps. the IR-spotlight Kemo B223 is also totaly out of stock

Good Job Man!!!  i already see your video, its great!!! i have a question for you, is just about what kind of materials did you use for the ball?  it really looks nice, its plexiglas with sylicon and a rear projection material? congratulations for your job and keep in touch, i wanted to go two years a go to umea, sweden, also , the master of technology looks great!! but some job here didnt let me out of here, but im still working on interactivity, it will be nice to keep in contact, chers…

Amazing stuff! cant believe I missed this one!

Great work man hope your keep us updated
