Multi-sensory experience

Second (see Fig. 24.3), as a user s experience is dynamic and context-dependent [23, 25], it is inevitable to consider how multiple contexmal factors may influence user experience. For example, companionship is a powerfid factor to have an impact on user experience [26]. It also requires attention that a user s multi-sensory experience may vary dynamically at different usage phases [27, 28]. Without tackling the contextual factors, user experience or evaluation may become ecologically invalid [29]. In addition, it is better to avoid treating a product as a starting... 

Furthermore, multi-sensory experience design has also attracted more and more attention since user experience is closely related to how the senses are stimulated and gratified [39 1]. In addition, it should not merely focus on visual aesthetics but should consider all of the senses [42]. Actually, user experience can be enriched to a certain extent if there are more sensory modalities involved [40] and more sensory memories activated [43]. Researchers have studied sensory experience from several facets such as roles of the senses [44], sensory importance [27, 28] and various kinds of interactions between senses [45]. 

To facilitate the effectiveness and efficiency of context-based multi-sensory experience exploration and design , a prototype CMSES with a SCS is proposed. The CMSES and SCS are demonstrated using a three-stage case smdy on a biscuit container design. Details are presented in the following sub-sections.

The main purpose of the first stage of the case study is to explore knowledge regarding users multi-sensory product experience from a contextual point of view. Based on the CMSES and SCS, this study illustrates how designers can explore and discuss users multi-sensory experience concerning multiple contextual factors and diverse individual differences. 

To discuss the multi-sensory experience, sensory importance is first examined. Participants attitudes toward the importance of each sense were solicited using... 

Considering possible individual sensory preference, the afterward questionnaire solicited participants preferences toward the flavour of the scent. The results show that 17 participants preferred no smell at all while 12 participants chose the same vanilla scent, 11 for fruits scent, 3 for other cookies scent and no participant considered perfume style. Thus, while planning or designing a product and its multi-sensory experience, design teams should have more careful consideration including possible sensory interactions as well as diverse individual sensory preference and habits.
