Week 5 - Day 2
Navigate using audio
Announcements
- Presentations review
- Feedback on the homework
- Makes you pay attention to things you already do
- Gives you better tools to critique the interfaces you use
- Feedback on the homework
- Audio 0:02:01.342658
- Did it change the way you might design an interface
- Yeah, knowing eight golden rules, etc.
- Experienced designers know that they don’t have all the answers
- You need user input
- Audio 0:05:23.445473
- You have to think about non-standard situations
- unpredictable usage
Expert Reviews and Heuristics
- Kinds of reviews
- guideline review
- heuristic review
- Audio 0:08:30.995883
- cognitive walkthrough
- formal usability inspection
Exercise
Examples:
- Google slides
- Advising appointment interface
- news site
- Intuitive to find the news I was looking for
- Inconsistent size of layout elements
- Advertisements auto-play and scroll with the page
- Audio 0:22:56.056939
- You have to be aware of competition
Think-aloud
- Audio 0:39:47.500776
- Talking through an interface task as it is performed
- Could potentially distract the user from completing the task
- not necessarily natural
- gives a better insight into how the user approaches the interface
- Audio 0:43:40.208723
Paper-prototype
- Audio 0:44:48.676886
- People aren’t as hesitant to request changes to it
- Faster to build
Survey Instruments
- Audio 0:48:28.430657
- what are things you need to think about when designing a survey?
- Having good representative users
- Don’t bias your questions
Acceptance tests
- You can’t have subjective requirements
- Can’t be “easy to use”
- Has to

consistency inspection | expert review which checks if the interface has fonts, color schemes, layout, etc. compared to other common interfaces |
formal usability inspection | expert review styled like a courtroom meeting in which the interface is presented to discuss its merits or weaknesses |
cognitive walkthrough | expert review in which the expert simulates walking through the interface and performing typical tasks |
sight tracking | method for observing how users progress through an interface and what catches their attention |
