I am glad to share you this world premiere
A true multitouch water screen .
I have beeen working on multitouch setups for quite a while now ,
and sometimes i felt a bit frustrated by the haptic sensation .
So i designed this mt screen with a water curtain that flows over it .
Here goes my immersive solution .

Wow jimihertz thats awesome!
A really exotic multitouch screen! I can imagine this in every dolphinarium to amuse the public while waiting for the show!
Keep up the good work!

Cheers,
Greg

WOW! Jimi, that is a really lovely idea! It is a real creative approach! Besid that, if you are using FTIR this should get you rid of the compliant surface I would love to see more fluids under that water curtain! BTW: those processing sketches on vimeo are also impressive - are you planning to share them with the community? I have to adtmit that i did not found any good freely to use processing MT sketches at the time i was searching the web…

Keep up the great work!

Cheers,

Yes!

It was only just the other day that i was telling friends that you can mix water with electricity! 

I love it!

Thxs for your enthusiasm !

are you planning to share them with the community?

Of course, i put a new topic on the software section .

Extremely cool. Anyone else envision that in a Los Vegas Hotel lobby. I did not realize that you could create a setup like that!

Well done Jimihertz!

Looks like you’ve taken the Ripples application to a whole new level!
It’s great to see people thinking outside the box.

Keep up the great work!

I f-ing love this thing! You officially have best Ripples software in world Could you get me more details for frontpage?

I think in future we will interact with data as if it were fluid… so this is very inspiring

I wonder if you could create a thinner stream and use it for tactile feedback somehow.

As always jimi keep creating great ideas!

Awsome.. one of the best ideas I have seen in a while, mainly because its so haptic and “real”.
Slick implementation as well, I can imagine the hours and trouble it took to make it work.

great job jimi!

Interactive drops of water in the open source community

This has me getting ideas.
[plastic touch section]
[water]
[FTIR]
Could something like that work.  A dry version of it.  Avoids all the battles with silicone.

Also makes me wonder if air flow generate between silicone and the Ftir could cure its sticking problems.

Might work, but i doubt it would work better than the silicone.
it would probably end up something like this :

Also, awesome stuff jimi!
It looks kind of splashy though

Notice something about that dye video its working in direct sun without filters.

Silicone has it limits.  IR filtering materials used on cars also has it limits.  When the material gets hot enough its filtering feature fails since it becomes a IR source itself.

Water on the screen can be cooled.  This could be the solution to direct sun and other IR sources.

That video is a extremely soft plastic.  I was thinking something more rigid as a top section so it only like a 2 mm of water across the screen surface max.  Just enough so nothing can stick and to cool it not more.  Sticking is a major problem with the non direct to screen silicone method.  They are going threw texturing and all sorts trying to avoid it.  Now if a small amount of water/oil/ok a liquid of some form between it and what it sticking to will fix it.  It could be the simplest solution.  So far I have seen no one attempt anything like that.  Think about it you have two metal surfaces that must not stick to each other but in contact you oil them to avoid problem.  Why does this logic not apply to touch screens.

Yes I was thinking about the of the limitations of the silicone system.

well, another problem here is that you would have to add something to your liquid to block out visible light, yet let the picture from your beamer (or alternative image source) through.

Really not thinking like me.

Number one that example with a light blocker is not a ftir setup.  Ftir setup has IR inside a bit of acrylic contact with the acrylic causes it to be release for the camera below to see.

Now camera can have a light filter on it.  Issue you run into is in direct sun the surface of screen where IR blocking matterial ie the plastic surface you touch or the acrylic gets hot enough that it ends up emitting more IR than what touching the acrylic will release.

So effectively the camera ends up seeing a white out.  Now finding a clear liquid that has good IR blocking property that you can keep cool that is not going to kill people would be kinda idea.  If you still have to have IR blocking material what is used on car windows and the water under it just cooling for it that would be fine too.

Currently the silicone surfaces are using air as there liquid.  Two major problems AIR is compress and expands a lot number 2 they don’t seal the edges so the air can get press out equaling stuck.  Basically they are building a flat form of a suction cup and wondering why it is sticking from time to time.  Depending on texture to make it un stick.  So any defect in texture it will fail.  Also as anyone who as worked with silicone knows it don’t keep it shape over time.  So the textured shapes will deform off.  So replacing the screen comes a really common event.  Even just sealing the edges and having air presure under screen might fix some of problem. 

Reason why I am suggesting this it might be the way out of the texturing problem.  No need to texture would make ftir screen construction so much simpler and most likely last longer.

Also due to the silicone always being in contact with screen by some amount.  I suspect the high points of the silicone are the reason why raw finger on acrylic can be brighter than silcone on top.  Not all the light that should be staying in the ftir is.  Basically its creating interference and reducing performance from being in contact all the time.  Just raw finger on acrylic is temperamental.
