以榨汁機的使用來探討前期產品經驗中感官之重要度 / A User Experience Case Study on the Sensory Importance at the Early Stage of Using Juice Squeezer

摘要

使用者透過所有感官與產品互動，在每次的產品經驗中各感官所扮演的角色和重要度會隨著不同使用時期而有所改變。本研究根基於Fenko 等人(2010) 的研究，針對產品經驗中的使用前期( 一個月)，透過質性方法( 觀察法、訪談法、日記法)，探討四位受測者使用電動榨汁機榨汁之情形，並與相關文獻對照討論感官角色於不同使用時期之轉變，以及影響感官重要度之因素。

本研究發現使用時期的轉變是會循環而非直線性進行的，而每位受測者各個感官的時期變化也會有所差異，整體而言，在受測者第一次與產品接觸時，視覺為主導的感官，然其重要度在初次操作體驗中即下降，觸覺則因發揮了主要的功能角色，而提升其重要度，在接續一個月的任務操作中，各感官於初期的感受較強烈，並引發較多情緒和聯想。而在熟悉任務並習慣刺激後，再次造成感官重要度的轉移，受測者較容易發現問題和產品的缺點，並影響其原本對產品的評價，此外，受測者可能再度發現其他有趣地方，或對問題找到了解決方案，對產品更加了解，並可能在使用一段時間後，與其產生情感，引發老朋友般的感受。

Users build up their product experiences through all senses. Among each product using experience, the sensory importance change through time at different stage of using it. In the study, we base on Fenko et al.’s study (2010) and use three qualitative methods (observations, interviews, and diaries) to gather more detailed information from four female participants about the early stage of product usage, which is the key period for a user to evaluate a product.The participants are asked to squeeze juice with an electric juicer for a month and then the multisensory experiences and sensory dominance are discussed. The role of each sense and its importance would change through time. The results suggest that vision is the most important sense when participants getting familiar with the product. However, the importance of each sense changes right at the first time of operation. Touch, which is related to the main function of the product, raises its importance. Also, emotions and associations evoked by senses are very likely to affect the importance of each sense. Most emotions and associations are evoked at the early days because once after participants gain expertise with the task they would get used to the stimuli and have less feeling about them. However, they are more likely to find out problems or have further findings about the product and change their evaluations. After one month, some participants even report that they have the feeling like old friends with the product.
