Phenomena that characterize the interaction between users and systems.

The human

Perceptive, cognitive and motor characteristics of humans. User profile and its definition for designing and evaluating interactive systems.

The computer

Input/output devices. Interaction styles: commands, fill-in forms, menus, spreadsheet, direct manipulation, anthropomorphic styles of interaction. Advanced interaction styles: ubiquitous computing, virtual reality and augmented reality.

Usability and accessibility

Usability definitions and dimensions. Usability engineering.
Accessibility and W3C standards for accessibility.

Usability evaluation

Usability evaluation methods: heuristic evaluation, cognitive walkthrough, keystroke level model, experiments with users, observation, monitoring, logging, questionnaires, interviews.

User-centered design

The star life cycle. Requirements specification. Task analysis: hierarchical task analysis, use cases, scenario-based design. Prototyping: horizontal and vertical prototypes, mock-ups, throw-away, evolutionary and interactive prototypes. Design patterns. Physical design: Gestalt rules, colors, affordance. Formal design.
