Reactive Sytems

Interactive Sytems

- the Response is always fxed

designers oftehn use the word interactive to describe systems that simply react to input, for example,

describing a set of Web pages connected by hyperlinks as interactive media. -Usman Haque

Syn. Feedback Loop, closed inormation loop, serl-regulating systems, recirculating system

- The response is dynamic and dependent on the input

- Simple eedback loop- Has only one loop

- Can not adjust its own goals

Syn. Learning System, Sel adjusting system

- Can modiy its goals based on the eects o another system or inputs rom the environment

- Second order systems can be nested within one other and they can either reinorce each either or have

competing goals.

CELLULAR AUTOMATA

A regular grid o cellswith fnite states and a defned neighbourhood.

any dimension eg. on/o

Time = 0

eg. A cells neighbourhood can be itsel and its

surrounding cells in any direction up to 2 cells distance.

Cells are given a defned state to begin with.

Time = 1 unit

generation 1

Each cell assesses its own state and the state o its neighbours and responds according to a set o rules.

according to some fxed rule

Time = 2 unit

generation 2

Each cell re-asesses its own state and the state o its neighbours and responds according to a set o rules.

Time = 3 unit

generation 3

Time = 4 unit

generation 4

typically the rules are the same or all cellsand are applied to all cells simultaneously.

eg. I 2 or more neighbours are on,

turn o. Otherwise, remain on

CELLULAR AUTOMATA - Digital Models

Conways Game of Life -Neighbours = directly surrounding cells. States = live/dead. Rules: 1_cell with ewer than 2 live neighbours dies. 2_Cell with more than 3 liveneighbours dies. 3_Cell with 2 or 3 live neighbours lives to next generation. 4_dead cell with exactly 3 live neighbours becomes live.

Brians Brain -Neighbours = directly surrounding cells.States =on/dying/o. Rules: 1_o cell turns on i exactly two neighbours are on. 2_On cells enter a dying state.3_dy-ing cells go to o state.

CELLULAR AUTOMATA - Biological Model (mixing o liquids)

Mixing o two liquids appears random.

However, the process ollows a defnite set

o rules. Each molecules ability to move and

thereore mix depends on its own physical

properties and the physical properties o

its neighbours. These conditions are as-

sessed and direction and speed o motion

are determined accordingly.

CELLULAR AUTOMATA - Biological Model (bioluminescent algae)

Each cell undergoes a chemical reaction

activated by motion or its adjacent neigh-

bours.

CELLULAR AUTOMATA - Biological Model (conus seashells)

< http://en.wikipedia.org/wiki/Cellular_automaton>

Secretion o pigment rom each cell is de-

pendant on its neighbouring cells similar

to Rule 30 where cells are activated based

on a mathematical sequence o numbers.

CELLULAR AUTOMATA - Physical Model

< http://www.decept.org/nolie/index_english.html#video>

Dplacements -It consists o 24 cells

arranged in a grid.

Each an acts as a cell

and is activated ac-

cording to the game

o lie.

Hardware: 24 ans,3 Pico IP systems, 1

computer. Sotware:

Processing, PicoLib.

Evil/Live 2 - 256 hal-ogen lights and speak-

ers were arranged in a

16 x16 grid each acting

as a cell and ollowing

the rules o game o

lie.

Propagaciones - It consists o 50 small robots installedon top o poles. They are all made o similar circuits but each

looks dierent. They interact with people around them and

among each other by turning lights on and spinning around.

Each ollows the rules rom Conways game o lie.

Adaptive Fa[ca]de - An adaptive skin that isconstantly training itsel to understand the envi-

ronment. It uses an artifcial neural network thatresponds to the level o light in the environment

aiming to provide optimal light intensity or a

space.
