Study And Application Of Requirement-driven User Experience Optimization Strategy

With the development of technology, IT industry has been growing drastically, bringing smart devices like smart phones and tablets into our lives. These products distinguish themselves among traditional products by meeting’spiritual’ demands of consumers instead of’material’ demands. These’spiritual’ demands consist of psychological feelings, visual feedbacks as well as emotional experience in the course of daily use. How to improve the user experience of interaction with these products is the goal of their user study.Provided this goal, we refined the requirements and propose a metric to categorize requirements, by studying user experience related theories and categorizing driving requirements in the process of product upgrades. Followed by that, we illustrate the usability of this concept by several real cases.The first chapter of this paper focuses on the background, significance, goal and innovations of this study. The second chapter focuses on analysis of concepts related to user experience, and evaluation methods used in the process of software development. In the third chapter, we divide requirements into five categories, namely innovation, usability, feeling, emotion and influence, by applying big data analysis on requirements in real projects. The fourth chapter reveals that distribution of weight of requirements from each of the five categories varies depending on properties of different products and different stages during the development process. The fifth chapter targets at real cases, and applies the method introduced before to analyze the requirements in these cases, considering characteristics of middle school students. Finally, this paper is summarized in the sixth chapter, listing the shortcomings and unresolved issues in our work, which can be further studied in the future.
