From my previous field trip, it is quite evident that my CTT coursework is going to be about how environmental factors (water) affect the distribution (movement & survival) of sea animals (fish).
It’s basically going to involve water and fish.
But first of all, what is an interactive A/V system?
An interactive audio/video system is a system that accepts data input and processes the information to provide an audio/video output. The sources can be physical (touch, voice, sound or vision) or digital (eg. API). The output can either be audio, video or audio-visual.
Before finalizing my idea, I am being asked to generate questions and think of scenarios to ensure my idea/project fits the brief.
- Who are my users?
- Do they enjoy visiting the aquarium?
- Can an A/V system be used to depict how aquatic animals move and survive?
- Is the aquarium easy to locate?
- What will be the budget for this installation?
- How soon can it be built?
Luckily for me, my idea ticks all the boxes.
So what’s my idea again?
Build an interactive A/V system that shows how water currents affect the movement and survival of fishes. It is targeted for kids of ages 5-10, and the specific context is the Bristol Aquarium.
So what does it do?
The system receives physical data like the human touch, processes information, and then causes a disturbance in the water which in turn will increase the speed at which the fishes are swimming around.
So as an output/display, the fishes are swimming at different directions at an increased speed due to the water ripples formed.
The system will be designed in a way that it will be very easy for the kids to understand and interact with. The elements in the system will be:
How will it be built?
To develop something as exciting as this, we will need to consider the tools needed.
The basic tools required for this system are:
1. Touch screen computer (For processing and display)
2. Openframeworks (For creative coding)
3. GLSL Shader (For creating water ripples)
After proper evaluation of the idea, I found out I had only one input data for my system, I did further research and found out fishes react to sound.
Some fishes run away from sounds, some run towards it, and some don’t bother.
Another idea came for my second data input; how about when the user claps or makes a particular sound, a ripple forms which also increases the speed of the fishes swim?
I will be dropping details about the production side of things later on.
