Prototype critique

This critique is a structured approach to evaluating presentations within a Human-Computer Interaction course. Each member will present their design in 5 minutes, focusing on usability and accessibility issues. The audience will engage by noting criticisms and asking insightful questions about the design's context, target audience, and technological integration. The emphasis is on distinguishing personal biases from objective critiques based on established principles. Key usability aspects, including learnability, control, feedback, and flexibility, will be addressed to ensure designs are effective and user-centered.

  2. 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

  3. 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
