AEIOU Method
Objective
To help structure observations during field research, interviews, or ethnographic studies, in order to identify behavior patterns and unstated needs that the user does not directly articulate.
The five categories
- Activities: what actions people carry out, how often, and in what sequence. What are they doing and why?
- Environments: the physical and social context where the experience takes place. What features of the environment influence behavior?
- Interactions: the relationships between people, between people and objects, and between people and the system. What or whom do they interact with?
- Objects: the physical or digital elements present in the context. What tools, devices, or artifacts do they use?
- Users: who the people being observed are: their roles, behaviors, attitudes, and needs.
Advantages
- Structures observation without predetermining the conclusions.
- Makes it easier to compare observations from different sessions or researchers.
- Produces a systematic record that can be shared and discussed as a team.
Limitations
- It requires practice: observing without interpreting is a skill that develops over time.
- It does not capture inner motivations or emotions with the same depth as an in-depth interview.
- It can generate a large volume of notes that then require time for synthesis.

Common mistake
Interpreting instead of observing. The AEIOU method asks you to record what you see, not what you conclude from it. "The user opens the app, waits 10 seconds, and closes it" is an observation; "the user is frustrated by the slow loading" is an interpretation. Interpretation is a later phase: first observe without filters, then synthesize with the team.
