A Conceptual Design Specification Based on User Aesthetic Information Analysis and Product Functional Reasoning

User satisfaction with a product plays direct role in the purchasing decisions. With enrichment of material life and growth individual requirements, this is derived from requirement for functionality to aesthetics. Conventional design methods normally focus on achieving required functions where its specifications are mainly related certain functional or usability requirements. In recent years, researchers have made efforts develop supporting aesthetic activities during conceptual phase. However, most these hardly consider aesthetics consumers’ emotional needs. Therefore, study proposed user-driven specification integrating reasoning information analysis. The method consisted two tasks, construction mapping model implementation model. Firstly, was constructed capturing relationships between initial user experience (UX). Secondly, were selected, refined, optimized based A case digital camera carried out demonstrate feasibility effectiveness method. results showed that, compared candidates, UX enhanced by applying improved specifications.
