OBSERVING THE SMART TV-VIEWING EXPERIENCE BY A DIARY-BASED OBSERVATION METHOD

摘要

This study aims to observe user’s experience longitudinally in a natural context of use by using DRM (DayReconstruction Method). DRM is an observation technique that periodically surveys user’s experience andevaluates it systemically. In addition to emotions collected by existing DRM, we also investigatedcontextual information using structured questionnaires. Each questionnaire was conducted for one episodewhich is composed of specific actions that are taken, context of each episode, and detailed description ofmood and emotion at that time of episode occurrence with detailed reason. For a case study, DRM for thesmart TV-viewing was conducted. As a result, users showed different TV-viewing behaviors depending onthe day of the week. DRM also showed that users typically did not use the majority of the technicalfunctions provided by the modern TV sets popularly used today. Moreover, we figured out that manysecondary activities were conducted concurrently together with TV-viewing. The study suggested that adiary-based observation technique proposed in this paper can be used to analyze the context efficiently andquantitatively without bias.
