02. User Analysis
Understanding AlzGuard Users
Following the initial product evaluation, the second week of work focused on analyzing user needs, motivations, and usage barriers based on observation, desk research, and heuristic review.
Although AlzGuard targets individuals with Mild Cognitive Impairment (MCI), users show considerable variation in health awareness, technology literacy, and willingness to engage with digital tools. To better understand these differences, we conducted clustering based on attitudinal and behavioral dimensions.
User Clustering Insight
Users were segmented along two axes:
- X-axis: Level of health-related worry (cognitive concern)
- Y-axis: Willingness to accept medical or digital interventions
This produced four representative clusters:
| Cognitive Concern / Acceptance Level | Low Acceptance ↓ | High Acceptance ↑ |
|---|---|---|
| High Concern ↑ | Avoidant Worried but hesitant | Proactive Adopter Health-motivated doer |
| Low Concern ↓ | Disengaged Low worry, low motivation | Functional Pragmatist Feature-driven user |
