A study on the development of an emotional design three-stage system measurement tool based on Bloom's three-stage learning model

A systematic understanding of the emotional factors and characteristics that consumers (users) experience while purchasing and using products and services is essential for designing products and services. This study aims to develop a more systematic quantitative measurement tool for analyzing products and services beyond the conceptual stages of Donald Norman's 'Three Stages of Perception Theory of Emotional Design' (after this referred to as 'ED 3s'), which is based on Bloom's Learning Model, as a follow-up to the previous study, 'Feasibility Study of Conceptualization of Three Stages of Emotional Design - Focusing on University Industrial Design Education Course'. The literature review obtained 165 scale items with validity and reliability with emotional design. Eighty items were extracted through the first round of expert review to assign five items to each of the 16 item systems to fit into Bloom's three-stage learning model system (after this, referred to as 'BL 3s'). The extracted 80-item survey was distributed to a target audience of 20-50 people using smart-phones and smart-watches; based on the final collected survey data, factor and reliability analyses confirmed the validity of 77 out of 80 questions except for 3. The first pilot survey questions derived from this study will be compared with the results of the third expert open-ended survey to be conducted in the future, and factor and reliability analysis will be conducted through the final fourth expert closed-ended survey.
