Abstract: User value can be defined as desirable states of existence or modes of behaviour. Many user experience (UX) researchers have started to acknowledge user value. Value-centred design can help designers provide positive experiences to users. Although several studies have been conducted to define user value, studies that evaluate user value are difficult to locate in the literature. Many methods for evaluating abstract and ambiguous constructs are known. However, user value is more difficult to evaluate than other constructs because of its ambiguity and variability. In this study, value evaluation methods are reviewed and factors that the methods should consider are identified. Then, a value sampling method (VSM) that considers these identified factors is developed. A case study using the smartphone is conducted to verify VSM. The result of this study can assist designers to evaluate their product or service prototypes in terms of user value.

Keywords: user value; evaluation methods; VSM; value sampling method; user experience; smartphone.
