Ground design decisions within the foundations of HCI, including ergonomics, human factors, cognitive psychology, and the trajectory of computing from mainframes to ubiquitous devices.

Use cognitive science to build interactive systems people can understand, use, and trust.

Identify real user needs, define the right problem, and design interventions that fit how people actually live and work.

Develop grounded user understanding with personas, cultural probes, technology probes in realistic settings, and scenarios that connect user goals to lived context.

Run the iterative design cycle from analysis through prototyping and evaluation, selecting the right fidelity of probe (paper, functional, deployed) for the right moment.

Judge when iterative refinement is productive and when a fundamentally flawed starting point requires reframing the problem rather than polishing the solution.

Design navigation that works at every scale: local orientation through the four wayfinding rules, information scent and breadcrumbs at the page level, and global structure through network diagrams and consistent dialog patterns.

Organize screens for clarity using semantic grouping, alignment, white space, and redundant coding that ensures accessibility without relying on color alone.

Apply sound principles of grouping, redundant encoding, and mode design to physical devices and voice interfaces.

Design for global audiences by planning for localization, text expansion, culturally specific symbols, and the assumptions embedded in Western interface conventions.

Use aesthetics deliberately, understanding their role in building trust and differentiating products while avoiding cosmetic fixes that mask functional problems.
