Building Diy Multi-Touch Table Part 1

[chakespiares]

vas muy bien.

[jadejordan1]

nice 2:21 lol

[ovidiub13]

Part 2 please :D

[Vinod13071975]

Hey where is the part 2 ... i am stuck man .... please help if you can

[JFetskie]

God I wish I could get you to join our burningman camp!

[PumperDaisuMaster]

second part please?

[Bossa4Sol]

:) Amazingly funny

[Brytano13]

Check out the "Unfortunate News" Vid

[patooone1245]

i really would like to know every thing after this video...i woould like to know if you can make another, record it, and post it...i would like to make one for a project....

[HaloSpartan89]

i like this video but i dont watch the second video help

[jimrangeley]

Do you use IR LED's and is there a specific distance for them along the frame

cheers

[27367]

Hey where you can find that silicone rubber? in what can you "normally" use that for? I am waiting for the 2nd part...

Thnxs!

[driyanx]

the video great.

could u please upload the rest for my reference.

thanks

[Orbiter007]

Good work, I see you have scored yourself a well equipment work shop :-)

The outdoor shot of you hard at work - where was that shot, that looks like some dangerous cliff behind you.

Great video and did you win the science competition.

For those wanting an easier path to multi touch check out the iQRite Kitset 10 Point Multi touch frames for an windows OS

[shiftctrlhack]

that silicon stuff stinks bad doesnt it.. lol i used it on some of my projects too

[cjellwood]

anything is possible with the correct tools and information

[shiftctrlhack]

@cjellwood dam right man

[somchartju]

please upload part 2 fo the building becuase i want to make a project study..Thank

[Brytano13]

I'm sorry, I have been really busy with my current project. Swarm Robotics, I'll try to get it up soon.

[somchartju]

ok. Good idea

[somchartju]

Good..

[rj00001]

Could you sandwich the vellum between two pieces of acrylic? Or would there be diminishing returns.

[Brytano13]

I don't think that would work at all, I think it would diffuse the IR light too much. Would be an experiment to try.

[michillin212]

I read some guy did it. He got a 1/8" piece for bottom(I think) and 1/4" on top

[rj00001]

Great, Where did you find that?

[michillin212]

I wish i knew. =D

[paultje162]

Can u please upload part 2 of the building becuase iw ant to make a table to :P

[canberkcanay]

why are you using leds and webcam together can you explain it plesase because i thought that one is enough for a touch screen?

thank you

[Brytano13]

The camera picks up the the reflected light from your fingertips touching the top of the acrylic or projection screen. Using a software like tbeta, or touchlib you can convert those into touches then into mouse movements or clicks.

[canberkcanay]

thank you... the thing i have seen before was taking finger tip positions via webcam only, now the method that you're using is a bit different,you are enlighting the finger with infrared leds than take the ir image of them. İs that make a big difference and does any webcam could take the ir image or the ps3eye is necessarily used?

and finally can i use transparent lcd monitor(i mean a lcd without a reflector layer) instead of projector

[Brytano13]

The PS3eye needs to be modded to work properly which is in the video. I don't know much about the LCD matrix's and multitouch. Take that to the NUIGroup forums.

[canberkcanay]

thanks for your interest...

[Flamesync]

Nice setup. Mine is smaller and not as neat. Can you post as many details about the hardware side of your project (LED array, psu, acrylic, vellum, etc), other than the cam , somewhere. Like, really detailed. I would like to make a clone of your table eventually for my own use.

Hope you win/won the science fair.

[aa2zz6]

how long did it take u?

[Brytano13]

About 2 months in programming, designing and construction.

[bmlbytes]

A couple questions I had.

1st. What are the compliant layers made of?

2nd. What types of LEDs?

3rd. What wireing diagram are we supposed to use?

4th. What do we do after we follow the entire video? How do we get it to display a picture, and what software do we use to track the fingers?

[Brytano13]

You can ask all these questions on the NUIGroup forums.

1. The projection screen is made out of Mylar, the compliant layer is made out of Xlyne (I think) Which you can get from an architectural firm who sometimes prints on Mylar. Mixed with pure silicone.

2. IR LED's

3. I'll get you the wiring diagram next Monday.

4. same as 3.

[Flamesync]

Your wiring diagram depends on the type and amount of LED's you use, and your power supply. I had this really good resource to help design the wiring diagram, but I lost it. I'll try to find it and post a link here.

[MrModMe]

Hey I have 2 questions for you.

#1 Does the LED array consist of only IR LEDs that emit light, or on the opposing sides of the emitters are there detectors?

#2 What is the silicone layer for? And I dont understand why you apply it to the mylar as well.

Thanks in advance

[Brytano13]

1# Its just IR LED's I did this to get the blobs in my other video.

2# When you drag your fingers over the top it looses its glow, basically for movement.

[MrModMe]

Thanks for responding. Also I was wondering what projector you used. Ive tried several and havnt had much luck witha good image.

Thanks in advance

[Brytano13]

Oh dang I had a terrible projector. I would try a new DLP mini projector.

[ps3moe314]

Great project.

On the second video, I was hopping you could show with more detail the led setup and how to do the final hook up.

Also, can you tell us where to find the program(s) needed in the comments section.

Just a suggestion

[Brytano13]

OK thanks I will work on the video next Monday.

[volk45]

Infra red leds or?

[Brytano13]

Tell me what you guys need, I will have to record the videos.

[bingleyson]

Where the hell is part 2?? O.O this looks great..Better put it up soon dude or people will think you failed..

[neelesh399]

hey add the second part as soon as u can.....its looks great::-)

[Brytano13]

Hey sorry guys! I'm just can't find the video, what do you guys need to know? I can answer things.

[TheMusicCloud]

part 2?

[Jagatia]

STILL NO PART 2. :(

[dahwan3D]

The lack of part 2 is causing blue balls... Help!

[Ba3dadBoy]

Nice good job man. Is the compliant layer fully necessary? What does it do beyond protecting the surface?

[BassistBoy17]

The compliant layer adds to the FTIR effect by generating more prominent "blobs" that the camera can track better. This is especially useful because you lose some "blob" when dragging, so the "blob" amplification is very handy. :)

[doncoxon]

keep it goin!

[mariobevilaqua]

Hello man!

Where is the part II???
