Take the card home.

Living matter doesn’t respond like a screen. Before you design an interaction with it, you need to know where the response lives.

What the card is

The card is a five-question tool from today’s lecture. Use it on your demonstrator to find where its response is located, then decide whether to design around it or move it.

The five questions
1

Name the trigger (a person, or the environment?) and the response.

2

Does the response still happen once the organism is no longer alive?

3

If yes: grind it into powder, does it still work? If no: one organism, or a relationship?

4

So what: keep it there and design for it, or move it?

5

What does it ask of you, of the person who uses it, and of the organism?

The four places
Substance

In the molecule. Grind it and it still works.

e.g. red cabbage
Structure

In the shape. Grind it and it stops.

e.g. pine cone
Living process

Needs one living organism.

e.g. mimosa
Relational

Needs a relationship between organisms.

e.g. bobtail squid and its bacteria

Keep locating.

Every week I take one organism through these same steps in a short Reading. Some of today’s examples started there.
