Overview

• Interactive prototypes allow you to work with the constraints of technology

• Discover new design opportunities through playing with these constraints

• Technology is not the only dimension of constraint


1. Interactive prototypes allow you to work with the constraints of technology


• Graphic sketch: layout, screen proportions, visual forms, interface controls

• Interactive prototype (Flash, Processing): animation, behavior, timing, real data


“You discover new possibilities of making & design through

putting things together.”Jack Schulze, schulzeandwebb.com


2. Discover new design opportunities

• Once you’ve turned your design into a system - you can play with the configuration of that system to generate new design opportunities.

• Work within constraints to refine your design

• Observe others interacting with the prototype in unexpected ways

3. Technology is not the only dimension of constraint

• You can also play with other constraints in the prototype– Physical form (it’s heaviness, stiffness)– Affordance (what can I do with it? It

can be held, thrown, squeezed)– Narrative (why would I want to do this?

What is the meaning behind this interaction?)


Use other forms of prototyping


Summary

• Interactive prototypes should be part of early design exploration

• By creating interactive prototypes you:– Discover and work with the constraints of the technology– Play with the configuration of the prototype to change

constraints and discover new design opportunities– Observe others interact with your prototype, sometimes

in unexpected ways, and discover new opportunities

• Technology is not the only dimension of constraint


Implications for physical prototyping tools• Help me understand the constraints• Help me play with constraints

– Easily reconfigure the system– Suggest technology alternatives

• Help me test the constraints with others– Robust– Easily reproducible, transportable

• Help me play with constraints in other dimensions– Physical form of the prototype– Build new shapes– Attach to existing objects
