ABSTRACT

User experience evolves in accordance with users’ attitudes, habits, and personality, as well as their prior experiences. Even though there are attempts to holistically frame the long-term experience of interactive products, there is still debate on how to guide designers in the design process of those products. To tackle this issue, this paper proposes the usage of Path of Long-Term User Experience (PLUX) model in design process. To interrogate the usefulness of the model, we conducted two studies. First, we adopted, adapted and tested the applicability of the backcasting approach, together with the visual materials that could be used in the design process. Following this, we tested the effectiveness of using the PLUX model as a guidance tool in designing interactive products. The PLUX model together with the backcasting approach helps designers to better ground their decisions in the design process and to find ways to enrich long-term user experience. The stages of user experience as well as the human and product-related qualities of the PLUX model facilitated in-depth reflection, and espoused creative interpretations of these qualities for ideation. However, the high level of detail is found limiting at times, depending on the ways the model is utilised.

摘要

用户体验随着用户的态度、习惯和个性以及他们之前的体验而发展。尽管有人尝试从整体上构建交互式产品的长期体验，但对于如何在这些产品的设计过程中指导设计师仍然存在争议。为了解决这个问题，本文提出在设计过程中使用长期用户体验路径（PLUX）模型。为了询问模型的有用性，我们进行了两项研究。首先，我们采用、调整和测试了回溯方法的适用性，以及可用于设计过程的视觉材料。在此之后，我们测试了使用 PLUX 模型作为设计交互式产品的指导工具的有效性。PLUX 模型与回溯方法一起帮助设计师更好地在设计过程中做出决策，并找到丰富长期用户体验的方法。PLUX 模型的用户体验阶段以及与人和产品相关的品质促进了深入思考，并支持对这些品质的创造性解释以供构思。然而，根据模型的使用方式，有时会发现高级别的细节是有限的。
