- Assemble materials needed to support evaluation
- Run pilot studies
29
Address practical issues
- Who
- What
- Where
- How
- Any constraints
30
Cognitive walkthrough
- Will user know what to do?
- Will users see how to do it?
- Will users understand feedback?
31
Some interface types
- Command based
- GUI
- Virtual reality
- Mobile
- Speech
- Touch
- Haptic
- Tangible
- Wearable
32
Benefits/Problems interaction design
- Good - minimise mistakes with safety critical equipment
- Speed up frequently performed operations
- Bad - Interactive products error prone
- Slow, inefficient interactions with product
33
Use for Scenario
- Establish requirements relating to activities and interactions
- Used as prototyping tools
34
Observing users benefits/disadvantages
- Observation reveals what people actually do
| - Actions may not explain why users do what they do
35
Ask users benefits/disadvantages
- Simplest way to find out about them
| - Sometimes what they say isn’t what they mean
36
User experience goals
- Motivating
- Helpful
- Exciting
- Enjoyable
37
Digital divide
- Gap between those with access and those without
| - Lack of knowledge, lack of resources
38
Conceptual model of interaction
- Environment
- Actions
- Concepts/objects
- UX goals
39
MVP ( Minimum viable product)
- Create product with minimum features for viable product
