TadPool:

The goal of this sub-project is to explore possible interactions with tadpoles in a fun and interactive way. Our experiments are based on two papers [1,2] published by the Aizenman Lab at the Brown University. This project is conducted in collaboration with the Do It Yourself community lab, LaPaillasse.

Introduction:

During early development of Tadpoles, visual avoidance is tuned to a specific stimulus size and is sensitive to changes in contrast. How, can we take advantage of that behavior to make possible a interactions with tadpoles ? Inspired by a first paper [1] and our own experiments, we got pretty good results with the following setup:
  • A CRT screen is – such that the screen is in a horizontal position.
  • Tadpoles are put in a large petri dish and the border are covered by a black tape. Use an open top tank, the ceiling of your chamber is can cause all sorts of light reflections from the screen underneath.
  • Find a water level such that Tadpoles always swim along the bottom and that they make a 45 degrees angle with the bottom.
  • The ambiant light in the room should be relatively low, but not too much otherwise your tadpoles will be falling asleep.
  • To get better results, try to do the experiments in morning, tadpoles are stubborn and when it's tool late they just won't move at all.

Gameplay:

The following observations give us clues to develop a gameplay:
Tadpoles reacts better if the movement is smooth and slow. If the tadpole doesn't react, don't try to stimulate it once gain immediately - you will only habituate it (they stop reacting to the dots really quickly). Wait for a while (20-30s).

Other Notes/Observations:

  • CRTs tend to heat, and as the water becomes warmer, the tadpoles seem to get drowsy.
