2.1 Definition of Human-Centered Design

Definition: Human-centered design is an approach to problem-solving that involves deeply understanding users' needs, creating solutions around those needs, and continuously refining those solutions based on user feedback[1],[2].

The ISO 9241-210:2010(E) standard defines human-centered design (HCD) as “a method for designing interactive systems that focuses on the needs of users.”

The primary principles of HCD include empathy, collaboration, prototyping, and iteration.

Landmark Academic Papers

Design principles for virtual humans in educational technology environments — Scotty D. Craig, Nicolaus L. Schroeder (2018). International Journal of Artificial Intelligence in Education · doi:10.1007/s40593-017-0148-y · ~150 citations · tier: contemporary

Synthesized human-factors engineering principles for designing pedagogical agents. Showed that voice, appearance, and persona of virtual instructors systematically affect learner cognitive load and perceived credibility — establishing that LE must integrate psychological design alongside algorithmic design.

The voice quality of pedagogical agent impacts learning and agent perceptions — Ryan F. Siegle, Scotty D. Craig (2024). Journal of Computer Assisted Learning · doi:10.1111/jcal.12997 · ~20 citations · tier: contemporary

Empirically demonstrated that voice quality (prosody, naturalness, warmth) of a pedagogical agent significantly affects both learning outcomes and learner perception. Illustrates the meticulous human factors engineering required in modern AI-driven learning systems.
