Enhancing User Involvement Studies Using a Scenario Co-build Approach
Chun-Hsien Chen,Nai-Feng Chen,Li Pheng Khoo,Chun-Heng Ho 한국디자인학회 2015 디자인학연구 Vol.28 No.1
Background : In user-centred design, user involvement studies are oftentimes conducted to gain an insight into user experience (UX) in order to create more consumer-focused products. However, designers usually face the issue that UX is subjective, dynamic and can be affected by diverse personal and contextual factors. Although scenario technique has been widely used to provide a specific context of use during user involvement studies, individual differences on ideal usage scenarios are frequently neglected. Consequently, it becomes a challenge for companies to offer customer-focused products with a large degree of personalization. Methods : This study revisits existing methods and proposes a prototype Scenario Co-build System (SCS) to assist designers in planning and co-building more realistic scenarios with users to strengthen the understanding of UX. The basic characteristics of co-built scenarios are presented and five development stages for implementing the SCS are described. Results : A case study was conducted to illustrate the capability of the SCS and demonstrate how designers can gain an in-depth understanding about UX. The results were promising and reveal the potential of the proposed method. Conclusion : The SCS provides more customized scenarios for users to experience a product. Designers can explore UX in a more comprehensive manner via considering individual differences and multiple contextual factors. From the case study, it appears that scenarios are capable of influencing the sensory, cognitive and affective aspects of UX. Thus, designers should pay more attention to the diversity in users" ideal usage contexts and how this may affect their product experience.
