Understanding of usability evaluation structure in actual environment that considers user's desire for using a interactive product

本研究旨在了解互动产品(如家电)在使用者实际环境中可用性评估的心理结构。研究发现，用户产品操作的自我效能感和产品参与度对产品评价有较大的影响。另外，在产品的长期使用中，核心评价点也逐渐发生变化。它从“易用性”转变为“使用的快感”。这种变化在使用后大约半年发生。

The purpose of this study is an understanding of the psychological structure of usability evaluation for interactive product such as home appliance in a user's actual environment. It has been revealed that the self-efficacy and the product involvement of the product operation of the user strongly influence the product evaluation as a result of the research. In addition, the core evaluated point is gradually changed in a long time use of product. It changes from "Usability" into "Pleasure of use". This change takes place after use around half a year.
