Lesson 4: The User-Centered Design Process

User-centered design (UCD) means involving real users from the start. The process often follows design thinking: empathize (user research), define (gather requirements), ideate (brainstorm designs), prototype, and test. In UCD, we create personas (fictional user profiles) to represent target users. For example, a persona might be "Juan, 45, farmer with limited internet skills," guiding design choices (big buttons, Tagalog language). You'll also learn methods like interviews, surveys, and observation (contextual inquiry) to discover what users really need.

After analysis, design low-fidelity prototypes: sketches or paper mock-ups to explore ideas cheaply. Then move to high-fidelity prototypes (digital mock-ups or even coded interfaces) for user feedback. Crucially, HCI emphasizes iteration: test early and revise. For instance, one might test a wireframe with five users, gather comments, then refine the design. In Philippine schools, students might do group projects where they interview actual local users and present iterations of their interface. Always document feedback and keep improving; this iterative mindset is a core outcome in CHED-aligned curriculum.
