touch tank

Interactive projection walls and floors - chances to play & learn in aquariums by Martin

Below are 9 examples of interactive projection walls, floors and touch tanks. I collected them from the internet, with the selection criteria that they have applicability for use in aquariums. Therefore, most of them have an aquatic theme, are animal related, or are educational.
If you don't have time to view all nine examples,  just go to no.s1, 6 and  7 for the top of the bunch.

1st example: Touch Tank
Depending on the species, touch tanks can be controversial. But here is a touch tank that is politically correct.


Okay, it is not the same as a real touch tank, but the water simulation in this clip looks quite realistic, and with the right display (software) it could encourage learning. People can point to plastic bags floating in the water and remove them from a turtle's swim path. The possibilities are endless and the touch tank's layout encourages social interaction. 

Click on the link below to see another video of the same "touch tank" at a different location.

There is a mirror installed above and behind the touch tank in that location.
If there are large crowds - as shown in the photo below -
you can easily look over the shoulder of people in front of you.
The photo below shows the mirror more clearly.

2nd example: Touch Wall
This video shows an interactive projection device installed in an office space. The device tracks visitors walking by and translates the motion into ripples and waves along the screen. 
This could be nice (and expensive) along a boring aquarium hallway; as long as this technology is novel visitors will have a blast with it.

The sound in the video is quite impressive. In animated movies the sound is key to bringing the movie to life. The same holds true for these interactives. If you go this route, great sound effects are a must and will add a lot more fun to them. 
As you can see from the clip below: similar concept, even better graphics... but no sound.

3rd example: Touch Wall without sound
This touch wall was designed by q-bus Mediatektur, the company that also conceived the touch tank in the first example

Here a link to another hallway example: http://www.youtube.com/watch?v=Z3BJqSIK890
but without an aquatic theme. Playing time 6 seconds

4th example: Interactive floor
This example is from the Science of Survival exhibition at the Science Museum, London. The visitor can step in a pool with clown fish. The animation of the clown fish is good. Watch to the end to see a person stepping on the floor projection.

http://www.youtube.com/watch?v=uPpcjES7WAE
The text in the projection reads:
Of every 100 drops of water on earth:
97 are too salty too drink
2 are locked in ice
1 is fresh water 
I guess the point is, if someone is playing with the fish eventually that someone -or some bystanders- will read the text.

5th example: Interactive floor
Here is another floor projection where you step on the fish and the fish shoot off - not much to it, but I included it because of its aquatic theme.


http://www.youtube.com/watch?v=50fE4KfsSWE

I found another interactive floor but this time without a projection - it is an audio set up. It is located in a brightly lit mall space. The visitor moves on a patterned carpet and when the camera above registers that they are stepping on a certain area it activates a sound bite.  Check it out at the link below, it's worthwhile to see what other things are possible with floor animation.

I assume the circles are only for fun; as far as the technology is concerned no carpet or pattern is needed.
But this opens interesting possibilities for aquariums: What if there are dangerous fish lurking in your path? They could - half concealed  - either be woven in a custom carpet or simply painted on the floor,   and as the visitors step on them they activate a sound bite: a scream of pain, "you-are-dead" spoken text, etc.

6th example: Water Board
This three and a half minute clip is worth watching to the end. Or jump forward to the last quarter of the video to the see its educational potential and how visitors can interact with their all or parts of their bodies.


There is no jumping up and down or dancing going on - this is more brainy. But it looks like plenty of fun and many kids could interact with each other making a chain of body parts (like arms) where the water runs from one to the next. Or a parent is standing tall in the middle while the water splashes on the children to the right and left.

Mike Burton is the creator of the WaterBoard, which was a winner of the 2007 RSA Design Directions Award. As far as I know, it is only conceptual.

The basic components are an opaque board measuring 2.2m x 8 m, four projectors and four cameras for back-projection and detection. The users can draw (or erase) lines to manipulate the water or use their limbs or whole bodies, to alter the water's flow.

I couldn't find much useful - let alone contact - information on Mike Burton; and the 2007/2008 web site of the Royal Society for the Encouragement of Arts, Manufactures & Commerce (RSA) didn't have further information.


7th example: Funky Forest
Click on the video link below to see some great interaction, graphic art, and lighting. 


Funky Forest - Interactive Ecosystem from Theo Watson .

Guests can manipulate the water on the floor and divert it towards the trees to make them grow. They can plant and grow trees by leaning against the walls. The overall design and lighting scenario is simply superb.
Children creating trees

The Funky Forest premiered first in Amsterdam a few years ago. In 2009 a permanent and updated version with seasons has been installed at the Moomah Children’s cafe in New York City, and also in 2010 in the Art Garden of the Singapore Art Museum. 
The design/artwork is outstanding. Here are more photos:

Emily Gobeille and Theodore Watson are the creators of the Funky Forest. They have collaborated on several projects, and many of them are worthwhile looking at from an aquarium-adaptation angle.

8th example: Interactive Aquarium - Call in with mobile
To quote Tom Vanderlin, the creator of the Interactive Aquarium:
"Using computer vision the seascape will react to the motion of a user, seaweed will sway and fish will scatter. Users can then dial in with any mobile device and create a fish using their voice. As they connect in realtime the sounds they make are analyzed and create a dynamically generated fish."

The illustrations were again created by Emily Gobeille.

9th example: 3D mapping
If you don't want to watch the whole video (2.5 minutes) just watch the opening scene for the 3D effect and then jump to the1:00 minute mark to see some cool aquatic effects.


http://www.youtube.com/watch?v=GN3kuVuyxEw

Here is a link to a news report about it:
http://www.youtube.com/watch?v=mQWyOFIZhKs
and more information on what the future will bring here:

The 3D effect is somewhat lost on my 2D screen. From the reaction of the bystanders in the news features it must be highly convincing.


Summing it up
There is no doubt that interactivity will play a larger roll in aquariums - and in zoos - and in our life in general.  Touch screens, and motions sensors, and call-in-with-your-cell phone technologies are here to stay. The question is: what is the price tag - and how much value do you get for it in return in terms of increased revenue or attendance, conservation, entertainment, or education?

Technology in zoos and aquariums is frail and transient - I have seen several high-tech installations come and go during repeat visits to various institutions over the last fifteen years. As long as these devices are a novelty they will engage the visitors, and they have the potential to be fantastic education, entertainment, and conservation devices.

The novelty-factor made me wonder how easy it is to update the content, especially if your institution is frequented by many repeat visitors. How difficult is to keep the content fresh? On Theodore Watson's website I found the link to Openframe work.
The video is over six minutes - jump ahead to the 4:00 minute mark and watch it from there to get the basic idea.

made with openFrameworks from openFrameworks.

For information on the openframeworks visit their website: http://www.openframeworks.cc/
While you are there check out their gallery http://www.openframeworks.cc/gallery for other cool stuff - not necessarily aquarium related.
If your art or graphic department can manage your institution's website it might be able to handle this software and rejuvenate any content in-house, thus stretching the lifespan of these installations.
But of course you may also be able to outsource it. Click on this link to see an example:

Whenever aquariums stray away from their core business (animals/nature) they run the risk of competing with non-animal institutions (like science museums, natural history museums or commercial endeavors with deep pockets).

Speaking of advertising, if this technology interested you I recommend my previous blog entry where I show an example of an interactive wall screen in an aquarium.

Doctor fish tank - Big hit with visitors by Martin

I remember that a few years ago a small fish called Doctor fish (Garra rufa) hit the news and many blogs. The fish eat dead skin cells of spa visitors leaving the healthy skin to grow. An article from China Radio International has more on this.
Photo: photo.eastday.com

Now the fish has made it into public aquariums, or at least one aquarium, where visitors can submerge their hands into the water and see and feel (!) the fish nibbling on their hands.



Here is a short video clip:


Touch tanks are usually popular with kids, but adults are often reluctant to the get their hands messy, or even think it unhygienic and unhealthy. But apparently not so with this Doctor fish tank. Maybe because of its name or its uses in spas and for skin treatments, but I saw just as many adults - if not more - as kids trying to get their skin "cleaned".

Below: Happy adults getting their hands wet and cleaned

Here at the Shinagawa aquarium, Tokyo, they had two smaller cylinders tanks. A step in the front of the display allowed children to reach in.
 
I was very excited about this exhibit and couldn't wait to tell clients and the world at large about it. Since some, if not most touch tanks, are controversial, I thought this would be the perfect win-win situation: Visitors of all ages love to interact with these fish and the fish, I assume, love to eat.
But then I came across the following Wikipedia article:
Garra rufa can be kept in an aquarium at home; while not strictly a "beginner's fish", it is quite hardy. For treatment of skin diseases, aquarium specimens are not well suited as the skin-feeding behavior fully manifests only under conditions where the food supply is somewhat scarce and unpredictable.
End of quote

Does that mean the fish only nibbles on skin when it is starving? And, is it true? If so, it wouldn't be ethical to display them unless they are also fed otherwise.



No instructions - say it with a photo

I don't like reading instructions - anywhere, anytime. Saying it with a photo is so much faster and easier to absorb. I have now seen it used a couple times in science museums, which have some of the worst offenders when it comes to having to read long winding instructions before you know what you need to do.
The doctor fish exhibit had a big sign with many words of which I understood none because they were in Japanese. But looking at the photo I knew immediately what to do, even if I'd been the only visitor.
