Verified Competencies Demonstrated by Sudarat Persson

By completing this curriculum to the standards of the IxDF Educational Codex, Sudarat Persson has demonstrated mastery of how to:

  • 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.
