user centred design

we were introduced to a new module by Debbie this morning. The module is User Centred Design.

Design to create user experiences through interactive products.

Stages
1. Ask user what they want / what they involve
list of requirements - useability / usefullness
2. Develop alternative designs - different alternatives

a)conceptual - what we want it to do
b)Physical - colour, fonts etc
Think aloud processes 2/3 different prototypes

3. Building - Prototyping development methods

4. Testing and evaluating design

5. Final development

It is an iterative process (stages 1-4, 1-4 , 1-4,1-4,5 )we keep going through till users are happy before trial development

Use neilson, normans, principles
think aloud processes

we looked at how we create alternative design
user input , self input, alternative designs of similar products, colleauges input
time constraints

We looked at how choose alternative design?
testing and evaluating, feedback, feasability - financial, technical, time, staff
Most clearly meets the criteria of specification

we looked at how the ddesign stages are related
Lifecycle models eg waterfall methods

Question why we choose a particular method
Why we didn't chhose a different method

our assignment for this module will be to redesign product chosen for previous hci module
