Topic 1 - Human-Computer Interface Development
The interface design project encompasses many key elements such as the visual aspect, usability, information architecture, navigation, and transitions between screens, among other fundamental aspects for a coherent and efficient user experience.
Elements in a human-computer design project
Affordance: affordance is the ability of an object or interface element to be recognized and used exactly for what it was designed for without the need for prior instructions. Communicability: communicability is the faculty of the interface to convey to the user the logic of the design, the designer's intentions, and the interaction principles that guide the decisions made throughout the entire design process. HCI requirements: identification and documentation of functional and usability needs that guide the development of custom software.
Techniques for conceiving and modeling the human-computer interface
Requirements gathering: among the most used techniques to understand users are interviews, focus groups, questionnaires, and brainstorming sessions. These techniques are essential to define requirements that allow building custom applications and custom software oriented toward user experience.
Interface modeling and task analysis techniques: HTA analyzes high-level objectives and breaks them down into sub-objectives to identify critical points and potential errors. GOMS models the user's cognitive knowledge and is useful when users already know the tasks they perform well. CTT ConcurTaskTrees makes explicit the hierarchy and temporal relationship between tasks to achieve user objectives.
Human-computer interface design processes
There are different design process models, from a simplified lifecycle model to the star lifecycle that emphasizes iteration and continuous evaluation. Nielsen's usability engineering and Mayhew's proposals offer frameworks aimed at ensuring high usability throughout the product lifecycle.
Interface design and integration
Users should not be forced to follow a single interaction path to perform an activity. Alternative routes should always be offered, and excessive and indiscriminate use of confirmation dialogs that slow down tasks and end up being ignored by many users should be avoided. The design should facilitate efficiency, error tolerance, and recovery.
Final considerations
In the first block, we learned how to apply affordance and communicability in the project, as well as the design phases and the products generated in each of them. We saw types of representations such as user profiles, personas, scenarios, and tasks, and the general concept of requirements. In the second block, we reviewed practical techniques such as interviews, focus groups, questionnaires, card sorting, storyboarding, and brainstorming sessions, and when to use each one for gathering design requirements. We also addressed types of design processes such as the simplified lifecycle, star lifecycle, Nielsen's and Mayhew's usability engineering, and goal-directed, contextual, scenario-based, and communicability-centered design approaches. Finally, principles and guidelines that constitute good practices for modeling an interface were presented.
