Objective: This study aims to observe user’s experience longitudinally in a natural context of use by using DRM (Day Reconstruction Method). Background: DRM is an observation technique that periodically surveys user’s experience and evaluates it systemically. Observing user’s behavior is critical in identifying users’ implicit needs. Previous studies on observation techniques have mainly been conducted in forced and artificial environments. So far, it was difficult to observe user’s behavior in natural context. Method: In this study, in addition to emotions collected by existing DRM, we also investigated contextual information using structured questionnaires. Each questionnaire was conducted for one episode which is composed of specific actions that are taken, context of each episode, and detailed description of mood and emotion at that time of episode occurrence with detailed reason. Results: For a case study, DRM for TV-viewing was conducted. As a result, users showed different TV-viewing behaviors depending on the day of the week. DRM also showed that users typically did not use the majority of the technical functions provided by the modern TV sets popularly used today. Moreover, we figured out that many secondary tasks were conducted concurrently together with TV-viewing. Conclusion: The study suggested that a diary-based observation technique proposed in this paper can be used to analyze the context efficiently and quantitatively without bias. Application: It is expected that the proposed method could be helpful for understanding user’s implicit needs on the products.
