Human Computer Interaction

User experience (UX) elements

• form: graphic design, product design
• content: information architecture, audio-visual, text
• behaviour: interaction design observation

UX deliverables:

• analysis & research: personas, qualitative user research/reports, user stories, competitive analysis, scorecards
• design: functional specs, flow diagrams, UI specs
• prototypes: clickable prototypes, mockups
• visual design: polished design & layout, icons & graphic things
• technical communications: web content, help, guides, videos, localization

Terms of interaction:

• domain: area of work under study (like graphic design)
• goal: what you want to achieve
• task: how you go about doing it, in terms of operations/actions

gulf of execution: user’s formulation of actions ≠ actions allowed by the system gulf of evaluation: user’s expectation of changed system state ≠ actual presentation of that state

human errors:

• slip: incorrect action (need better interface design)
• mistake: may not have the right goal (need better understanding of system)

goals:

• efficiency/productivity? effective learning?
• usability goals: meeting specific usability criteria
  • effectiveness
  • efficiency (minimal steps, simple)
  • safety (does the system prevent users from fuckin up?)
  • learnability: people are impatient, manuals are tedious, nobody wants to fuckin do it. they should be able to learn the system in under 10 minutes.
  • utility: the extent to which system provides functionality that user needs
  • memorability: meaningful icons, command names, menus, so that the user can remember shit without always having to go back to the manual
• user experience goalz: develop the quality of the user experience (a e s t h e t i c, games)
  • design isn’t just about efficiency and productivity
  • the point is, do you feel nice and warm inside while using the system?
