“It isn’t the consumers’ job to know what they want.”
![Page 4: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/4.jpg)
“When the point of contact between the product and the people becomes a point of friction, then the designer has failed. !On the other hand if people are made safer, more comfortable, more eager to purchase, more efficient – or just plain happier – by contact with the product, then the designer has succeeded.” !
Henry Dreyfuss, Designing for People,1955

Why do user research?
To build empathy with others
To identify “trouble spots” in a design
To find the “negative space” where new ideas can emerge

Why usability testing?

Usability heuristics
![Page 46: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/46.jpg)
Nielsen’s heuristicsBased on a factor analysis of 249 usability problems
Widely accepted as the baseline principles of usability engineering
Molich, R., and Nielsen, J. (1990). Improving a human-computer dialogue, Communications of the ACM 33, 3 (March), 338-348.
![Page 47: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/47.jpg)
Visibility of system statusThe system should keep users informed of what is going on, through appropriate feedback within reasonable time.
![Page 48: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/48.jpg)
Match between system and the real worldThe system should speak the users’ language, with words, phrases and concepts familiar to the user, rather than syste-oriented terms. Follow real-world conventions, making information appear in a natural and logical order
![Page 49: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/49.jpg)
User control and freedomUsers often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.
![Page 50: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/50.jpg)
Consistency and standardsUsers should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
![Page 51: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/51.jpg)
Error preventionEven better than good error messages is a careful design which prevents a problem from occurring in the first place.
![Page 52: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/52.jpg)
Recognition rather than recallMinimize the user’s memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another.
![Page 53: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/53.jpg)
Flexibility and efficiency of useAccelerators - unseen by the novice user - may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.
![Page 54: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/54.jpg)
Aesthetic and minimalist design
Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
![Page 55: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/55.jpg)
Help users recognize, diagnose, and recover from errors
Error messages should be express in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
![Page 56: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/56.jpg)
Help and documentationEven though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.
![Page 57: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/57.jpg)
Interviewing
![Page 58: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/58.jpg)
“Tell me more”!
“Help me understand”!
“Why do you say that?”!
“Talk about ...”!
“Walk me through this...”

Avoid leading questions
Ask questions grounded in personal experience
Avoid complex, lengthy questions
Don’t defend; don’t offend
Controlling for bias
![Page 60: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/60.jpg)
Three kinds of interviews
Structured
Semi-structured
Unstructured
![Page 61: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/61.jpg)
Structured interviews
Exacting wording and sequence of question is predetermined
Good for quantitative research (e.g. opinion polls)
Produces highly valid, comparable results
![Page 62: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/62.jpg)
Semi-structuredTopics selected in advance
Sequence and wording determined over course of the interview
Some questions may go unasked
Script may evolve over the course of the project
![Page 63: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/63.jpg)
Unstructured
Questions emerge in context
Good for early stage, exploratory research
Most likely to produce unexpected results
![Page 64: Alex wright mons_workshop_051214](https://reader034.fdocuments.us/reader034/viewer/2022050714/55ac12fb1a28ab10588b4668/html5/thumbnails/64.jpg)
Assessing validityCredibility Is the participant believable?
Transferability Can the findings be applied to others?
Confirmability Can the findings be replicated?
