What’s a MTmini?
Materials
- Cardboard Box
- Piece of Clear Flat Sturdy Material (ie. Glass, acrylic, plexiglas) Paper (ie. printer paper, tracing paper, almost any paper)
- Webcam or Video Camera (I use a Philips SPC900NC)
- Computer (dual core recommended, but not needed)

How’s it Work and What Conditions are Necessary?
For this to work, all you need is a room with (at least) some light. The results will be best when the room lighting is even (no bright lights shinning from one direction onto the multitouch pad).
When you place you fingers on the surface, shadows are created where your fingers are. The webcam sees these shadows and sends the image to the tracking software which tracks the shadows as they

This is so cool! I didn’t think I’d be able to make something like this from so little. Thank you!

Hey, where do I select which camera to use? I have two web cams (one built into my laptop), and the other a normal usb one. When I load up any of the apps (configapp.exe, mousedriver.exe, etc..) I get a bunch of windows but neither one of my cams are being used. Did I miss an important step?

Pretty sweet… what is nice about this was it was fun for me to construct with my 4 year old… Human interaction projects are amazing withthe kids…
Thanks for putting it up there.
May 1, 2008 at 8:03 am
Ryan, that’s great to hear! I’d love to see pictures. I’ll be putting a package of software together that will include some great demos that kids would love. Check back for updates soon. =)

I would love to install and try this but I think I will wait for the photo app to come out first thats what I really want anyways.
Email me when it comes out PLEASE.

I am thinking about making this into a Coffee Table type design to use with a PC hooked up to my living room TV.
Can you put a piece of plexi-glass over the paper and still have it function the same way?
Also, making the box bigger and more of a rectangle be a problem? (Length 6′ x 4′ Depth 3′)
May 1, 2008 at 4:21 pm
@ Ethan, a new download package should be out soon (including Photo App).
@Christopher, as long as the plexi-glass on the paper isn’t too thick it should still work just fine. The farther away your fingers are from the paper, the less contrast your finger shadows will have. A bigger size is definitely dooable =) check the rest of my blog out, and you can see I have a bigger Multitouch Table with visual feedback. So a large MTmini would work just as well! =) I’d love to see pictures/video if you do it.
May 1, 2008 at 6:01 pm
This looks like great fun! I set up the MTmini with my Logitech camera. Thing is, I’m finding it hard to create a result as good as that in your screenshot. Using the provided XML stops touchlib from working. I’m stressed out as I would love to play with this.
Any help appritiated,

Will there be an easy to install package (.deb or .rpm or .tgz etc.)for Linux anytime soon?
May 3, 2008 at 3:10 am
zmjjmz, I’m not sure yet if there will be a linux install package. Touchlib (the tracking software) does run on linux though, but you must compile yourself right now. If you’d like to compile yourself (doesn’t take too long) go here: http://www.multigesture.net/articles/touchlib-compiling-instructions-ubuntu/ for instructions on how to compile touchlib on linux. Smoke will also work on linux, along with the flash applications (some of which I’ll be releasing very soon).
May 3, 2008 at 3:47 am
People, if all you see is grey check if you have touchlib beta v2.0 instead of v1.0 its easy to get the downloads confused as they are really near in the same page. calibrating now…..hard work to do an night ……..good luck

May 6, 2008 at 7:47 am
Seth ~ I might have a solution to the lighting issue. Have you been to a restaurant that displayed a menu with neon grease pens? Same concept. Focus the light into the edge of the glass (plexi has been proven to work best). I think the camera will pick up on the light in the glass before ambient lighting. Maybe some leds powered by the camera usb cable. Another idea… Put a document protector over the paper allowing folks to draw or sketch with dry erase or wet wipe pens.
May 6, 2008 at 8:26 am
Hi Skip. I like your thoughts. If you look at the rest of my blog you can see I’ve build a Multitouch Table (with projection) and method similar to what you’re talking about (focusing light into the edge of acrylic).
For the MTmini, ambient light is actually a benefit. There’s isn’t really a lighting issue. As long as there’s shadows it’ll work. Shinning light into the sides of acrylic takes a lot more (not making this How-To as easy), but it’s a good thought. I tried to make the easiest working solution for people to get started.
As for projection, you can’t use projection without using infrared light. The light on the projector would confuse the camera (since it will see the projection), this infrared light is needed (which is just an added step to more work). If you’re interested in this, check out nuigroup.com where a whole community of people are building multitouch tables.

This MTmini page is only about building a non projector based multitouch pad. The rest of my blog shows some of the steps to building a full table, but I don’t have a full tutorial up yet. For information on nuilding a full table with projector, mirror and LEDs I would recommend joining nuigroup.com/forum where we discuss how to build these.

Hey man,
Awesome idea. Any chance we can incorporate this in photoshop? The main problem I would think would be that using a pen might not create enough of a shadow for the webcam to pick up under the normal ambient lighting conditions, but perhaps I am wrong. Also, does the camera’s response time really lend itself to such applications? Just some thoughts. Again, awesome design.

May 12, 2008 at 7:14 pm
@jae: I used a Microsoft NLQ-6000 notebook webcam in a box 7×7″. Works fine.
@MKNigol: The multi-touch box uses natural lighting.
@Alessandro: Are you seeing anything at all with your camera? If so, do you have more than one camera on your computer? Some multi-camera setups don’t seem to work. Otherwise, make sure you have enough ambient light outside of the box for your gf to cast a good shadow on the paper.
@Qebm: It’ll work in any container, but give a box a try first. It’s easy enough and will give you an idea of how this all works. Plus, it’s nice and light.
@Bavalova: Would be neat to have a paint program that worked with multi-touch. Not sure if you’ll have the precision you want though in Photoshop.

HI! I really really really want to do this but I downloaded your software and when i did the instructions (click config) all it did was bring up the command prompt window for like 3 seconds and dissapear again. Im using a windows xp and it hasnt been going well. 
I ‘ve already made the box and everything! It may be because I like messing with codes in notepad and I may just need to erase everything form computer again. Hopefully you know a solution but if not I ‘ll see what I can do.
May 13, 2008 at 1:50 am
I have had similar problems with the software. When I double clicked on the configuration batch, a message popped up saying, “the application has failed to start because cv100.dll was not found. Re-installing the application may fix this problem”. This is also the second time i had to download the software, the first time it wouldn’t unzip the main folder claiming there were no files in it. I am using XP home edition SP2.
Any help would be greatly appreciate. I really honor what you guys are doing here
May 13, 2008 at 1:58 am
@ Austin and Bryan: are you using the MTmini Software Package v1? Make sure you are using that package and not the touchlib beta v2 one.
@Bryan, the Mtmini Software Package v1 has the cv100.dll which makes me thing ur using the touchlib one.

May 14, 2008 at 5:05 am
to fix the issue where the windows after the first three are just black during configuration you need to find the brighness and contrast settings for your webcam and tweak them I did this and after about 5 minutes I found a brighness and a contrast setting that finally worked

Hey, great piece of work, that
I’ve sort of drifted here from the wii-whiteboard project. Sure, this one doesn’t have the display (btw: I know the way this works seems to preclude integrating the display with multitouch, but still – would love to see that sometime ), but that’s acceptable trade-off for me, as you’ve just saved me whatever the wiimote costs, thanks
I’m wondering, though, how does the software handle widescreen displays? I mean, all I have at home are those, and there are apparently no webcams (save for the costly logitech one) that do anything other than 4:3 format. Any information would be greatly appreciated (in absence of it, I guess I’ll provide some, as I’ll start working on my multitouch as soon as tomorrow )

Oh man, this is extremely cool<3 I need some help though… I followed everything in the getting started pdf. Configuration, server, and gateway bat files works great as far as I can see.
1) My entire touch pad is only mapped to the top left quarter of my display screen in Smoke_demo.bat. Is there a way to map the pad to the entire screen?
2) Are we supposed to keep the server and gateway .bat files open as we use the flash demos?
It’s kind of confusing because the configuration.bat had to be closed for the default smoke demo to work.
3) Flash still can’t register any touch events even though I gave permission to the ‘MTmini package v1′ folder.
Thanks. ^^

Here’s what you can do if you have low, inadequate light.
1. get a flashlight or more, make one from an LED and a battery (I found one in an old light of popsicle stick I bought for a quarter (it was expired though, still tasted good, a bit chewy)) or anything that produces light even a phone.
2. change the settings in your camera to inverted, I thought it was inpossible to do this but then I logged into yahoo instant messeger, chatted with nobody, turned on the webcam >preferences>camera settings>special effects, invert
3. then start the app. and use the light/s on the surface, you don’t even need the box! just in the air!

But in point 6., you suddenly talk about <camera input_device=”WDM_CAP” friendly_name”blabla” in the frist line. What is the difference and can you somehow explain it more easily? Do I need to add both lines? or what?

Hi Seth,
Just wanted to say thank you for the wonderful idea and project. It’s always great to be able to make something new from things we (hopefully) already have, especially when the whole is so much more than the sum of its parts. I’m a few years late, but I’ve just discovered the simple fun of webcam-controlled PC games and the dimension of human movement in the experience is almost magical.
Reading through your comments, I had to also commend your patience in replying to questions and posts. Done with great grace. All the best to you,
TY
May 30, 2008 at 8:44 am
Hi, I build the MTmini last night. It is cool. However I have some comments/questions. In the video we can see how windows are moved around, pictures selected and rotated, the piano being played, etc. I found that very difficult to achieve. Do you really know which picture you select or which key you are pressing? In my case I have no clue at all which makes it very difficult to use. What is your experience in this respect?
Cheers

i have a trouble. I’ve just created my MTmini.
When i try to run a C++ demo everything works.
When i try to open “gateway.bat” (after “server.bat”) and i click “start”, the cmd windows gives me these lines:
“UDP OSC server started on port etc”
“Received UDP Packet, Parsing OSC…”
“TCP XML/FLASH server started on port etc”
and then it gives me almost forever this line:
“Received UDP Packet, Parsing OSC…” continuously, scrolling down the window.
If i try to start a flash app nothing works.
I just downloaded the latest version of Java, and as i told you, the C++ apps work.

How do I put custom videos and photos into the “Photo” app in MTmini v1, other than putting a different video or photo in the same folder, and renaming it to an existing photo or video name in that folder?
Also, I’m having some difficulty running any of the Flash apps. I have to use mouse driver to get any response on the screen when I’m running a Flash demo.
1 more thing, do you know why the two [flash] applications “Ripples” and “Tangram” aren’t working?
I really need your help, and I’m a big fan of your site, project, and your apps.
Thanks in advance,

July 18, 2008 at 9:25 pm
@ Nick:
To add your own images/videos. Put the images and videos in their respected folders. Then double click on reload.bat which is inside the local folder. That’ll add all the filtes to their respected .xml file which loads them into the application.

July 23, 2008 at 7:53 pm
Hi, I tested your MTMini software / hardware proposal a few months ago and found it very promising, specially for those of us who can’t afford expensive technology.
BUT… I found just one thing missing at software level that avoids the regular use of your technology for day-to-day use.
It is necessary visual on-screen feedback of my hand position over the box BEFORE I produce a touch input… without that, I have to work blind.
I think you have done a wonderful job, but is like if you invented the mouse technology (hardware and software) and there is missing just one thing: the image of a mouse pointer on screen (Just imagine using the mouse trying to click in something without the pointer image on screen to guide you).
I think that, when the MTMini software is loaded an running, an additional and transparent layer should be displayed on-screen, all the time, showing the “shadow” of the hand that is captured by the webcam. This way, I can know where I’m going to produce a touch event beforehand. I think that this layer should be displayed full-screen for appliances like the mouse-driver you provided, and maybe just over the window of the multi touch app in cases like the one with the smoke app. Please contact me with any information regarding this “issue”, I’m a software developer and maybe I can add this extra feature by my self, with the proper guiding.
That’s all. Thanks in advance, and sorry for my English. (I speak spanish )
Bye!

thanks cerupcat…
It works really good. I used the built in camera in my labtop.
I wonder if you can eliminate the circles in the smoke_demo that appear every time it reacts to the movement (it’s a little bit destructing) and post more application/demo.
You do a good job though.

[...] È senza ombra di dubbio l’era del multitouch: iPhone e HTC Dream sono solo alcuni dei dispositivi che, implementando questa nuova tecnologia, hanno di fatto aperto le porte a nuovi mercati. Seth Sandler, studente dell’Università di San Diego ha così pensato di promuovere la costruzione di una tavoletta multitouch, realizzata con pochi componenti e senza dover spendere centinaia di euro. La MTMini è una sorta di parallelepipedo composto da una scatola di cartone e da un ripiano trasparente realizzato in plastica o vetro. All’interno del cubo troverà posto una webcam. Il tutto è gestito da una applicazione, la Touchlib, che permette di catturare una serie di eventi della dita sul vetro (tocco, rilascio, spostamento) e di tradurli in comandi da impartire al PC.

Ciao. Sono molto interessato a questo progetto e voglio porti un suggerimento: invece di far rilevare le zone d’ombra, provi a fargli rivelare dei punti luce ,in un ambiente oscuro, si potrebbe creare una tavola-computer simile all’interazione vista nel video Ayo Tecnology (http://www.youtube.com/watch?v=). se hai già pensato a questa alternativa rendi noti i tuoi pensieri.
September 21, 2008 at 7:28 pm
Hello. They are a lot interested to this plan and I want you carry a suggestion: instead making to find the zones d’ shadow, tests to fargli revealing of the points light, in a dark atmosphere, could be created a similar table-computer all’ interaction seen in the video Ayo Tecnology (http://www.youtube.com/watch?v=). if you have already thought next to this alternative you render you notice your thoughts. Thanks and compliment!

I tried the scale version (Mt Mini) which is slightly (very) inaccurate in the windows mouse driver field of things, thinking of trying the table as the mini box etc is a bit rough and ready. I’m using a Genius Eye110 webcam, am i doing something wrong? I used both baking paper and a4 printing paper. Also my webcam has a very small ‘veiwing area’ ! HHHEEELLLP!
September 21, 2008 at 7:47 pm
Last comment for me (i hope), I have not got a projector so am a little stuck with the table, could i also have the measurements?
Good Job on the weblog-did you create the software for the mt mini?
Good luck,

Could you use a colored glass, use some directional LED light bars, that would allow it to be built into a desk and it would look better than white paper.
Nice project, I will have to build one.

@ Alan: I use PD for only the basic desktop part of my AudioTouch OS (you can see videos on the video page), but all the applications run through flash with sounds played through flash. It wouldn’t be too hard to work with PD or MAX though since the tracker used sends OSC messages.

I have a question about setting up multiple screens! Say I have like 4 lcds in separate areas in a room. I know your software picks up light using a webcam thus determining where your fingers are. So hypothetically I should be able to use IR leds and do away with the pad as long as the software knows where the points of light are in reference to the cam. My question is can I hook up multiple webcams and use them together with this software? or does this software only support 1 cam?
November 9, 2008 at 5:21 am
i am 12 years old are i have made a small touch pad and a large one the larger my touch pad got the beta it got but i am still having trouble with it. it is always jumping around and staying in a small part of the screen. could someone please tell me what to do about it. cause it is so awesome and i am a computer gooroo but i can not fix his one so please someone help me!!!!!!!!
November 9, 2008 at 5:37 am
@ squddy: Make sure to follow the guide here: http://wiki.nuigroup.com/Getting_Started_with_tbeta including the calibration process.
@ Twistedted: Yes, infrared LEDs would be fine, as that’s what I use for my multitouch table (not pad). You can’t use multiple webcams right now, but that’s a future feature. You can however load multiple instances of Tbeta each with it’s own camera.
November 9, 2008 at 7:41 am
hi. i just did what u told i have calibrated and stuff but still how do i get i it to work like a mouse?
November 9, 2008 at 9:08 am
please help me i have made a a touch pad and it dose not work very well i have done what the instructions told me to do but it will not work very well. it will jump around and stay in a part of the screen. please someone help me!!!!!!!!!!!!!!!!
November 9, 2008 at 6:55 pm
squddy: Calm Down lol. Posting multiple times isn’t going to speed up help. You need to go to the tbeta.nuigroup.com website and go to downloads tab and download the demos zip file.
As for a mouse program, you can get it here: http://nuigroup.com/forums/viewthread/3447/
Please post any other questions on nuigroup.com/forum instead of my blog. They can help you faster than I can. Thanks!

You’re awesome… sweet!
November 25, 2008 at 6:08 pm
looking around your site and NUIGroup I found my answer thanks!
November 26, 2008 at 3:38 pm
Could you tell us how you built and what you used to write your AudioTouch OS?
looks like you did it within Mac OS (pure speculation) since you used one of their default backgrounds (hint maybe…)
or was it pure flash in fullscreen…
November 26, 2008 at 7:38 pm
UIGeek, NUIGroup is definitely the place for all the help you’ll need It’s the best resource.
As for my “OS”, it’s not really an OS, it just loads various flash applications I’ve written. The OS part is also written in flash (as3). So pure flash all the way Most of the applications you can download on my downloads page and if you have a coding background, you can get the code for various AS3 applications on nuigroup.com and touchlib.googlecode.com
November 26, 2008 at 9:31 pm

Hey there! This project is awesome, as soon as i saw your vid i made my own…but:
the calibration is a hard thing to do, well i have to work on my lights around me, so its working better….but my biggest problem is: Theres always a “Touchpoint” on the uper left corner of the screen, thats annoying, because i cant do anything without malfunktioning…the curser always moves rapidly up there and if i touch anywhere else, it just messes my Desktop and open Windows up…plz what ccan i do…
I tried it with “normal” mouse plugged and unplugged, same problem, also there is no significant shadow or black Dot in my upper Left corner of the Device…
…hope you can help me^^….would be fine if you could send me the solutian as a mail or smth like that^^

Please reply
December 17, 2008 at 8:22 pm
Zack, please try the new ‘tbeta’ download package and not the touchlib one.
December 17, 2008 at 8:26 pm
@ Tikian: you have to be more specific.
@ Aku Ryou: I’m not sure what the problem is. Just experiment more with the lighting and make sure you press the background subtraction button.
December 19, 2008 at 6:49 pm
Hey, have posted before, just to say that the new software is 100% better than your previous release, more functional, also is the new mousedriver. Lighting is an issue with anything using a camera e.g. greenscreen in my case, but well Done!
December 22, 2008 at 3:07 am
This is a genius idea! I personally can’t do it since I don’t have a webcam or money, but I like the concept. Just a few thoughts without actually using it:
- Use a clear plastic wrap instead of paper? It might make it more smooth for the finger.
- Project the screen to the paper. (this could help even out the lighting?)
- Try drawing with it using a pencil. (will need replacing the paper for every drawing, however.) It’d be neat to see someone figure out how to use an eraser, too.
Thanks! If you want to reply to this, you will probably have to email me because I won’t be checking this often (sorry 
).
December 22, 2008 at 7:20 pm
I know, but wouldn’t a marker cause a shadow like a finger? Then get a drawing program like paint and just use your finger

thanks again. wonderful job. maybe you should try this on windows 7. the beta version is not now (but limited). since the windows 7 has multitouch properties, would it mean that we could not use the mousedriver? just askin’ ^^
