Prototype critique IMD07101: Introduction to Human Computer Interaction Tom McEwan 2010/11
Structure • Tend towards Adult communication rather than • Nurturing Parent • Controlling Parent • Free Child • Adapted Child • In your existing groups • Each member present in 5 minutes to the others • Everyone note criticisms of usability and accessibility • Ask questions about People, Activities, Context, Technologies – eg who, what, where, and how • Decide which presentation has the best potential • highlight usability and accessibility issues addressed • Refine those pages and prepare to present in second half • One group (or individual) at a time – present to the class (5mins each). • Tell us • for whom you are designing, • what their goals are, and • how your design helps • Members of the class critique each presentation • Distinguish between their personal preferences, and objective criticisms that refer to some external benchmark or principle
Criteria for criticising • Accessibility • “This is for everybody” - when plainly it’s not • PACT • Focus on features ... or benefits? • Focus on tasks/interactions ... or activities/goals • Usability • Learnability • Effective • Control/Feedback/Navigation • Safety • Accomodating: Suitability/Style/Flexibility
