Abstract

Although the concept of user experience includes two key aspects, experience of meaning (usability) and experience of emotion (affect), the empirical work that measures both the usability and affective aspects of user experience is currently limited. This is particularly important considering that affect could significantly influence a user’s perception of usability. This paper uses image schemas to quantitatively and systematically evaluate both these aspects. It proposes a method for evaluating user experience that is based on using image schemas, sentiment analysis, and computational semantics. The aim is to link the sentiments expressed by users during their interactions with a product to the specific image schemas used in the designs. The method involves semantic and sentiment analysis of the verbal responses of the users to identify (i) task-related words linked to the task for which a certain image schema has been used and (ii) affect-related words associated with the image schema employed in the interaction. The main contribution is in linking image schemas with interaction and affect. The originality of the method is twofold. First, it uses a domain-specific ontology of image schemas specifically developed for the needs of this study. Second, it employs a novel ontology-based algorithm that extracts the image schemas employed by the user to complete a specific task and identifies and links the sentiments expressed by the user with the specific image schemas used in the task. The proposed method is evaluated using a case study involving 40 participants who completed a set task with two different products. The results show that the method successfully links the users’ experiences to the specific image schemas employed to complete the task. This method facilitates significant improvements in product design practices and usability studies in particular, as it allows qualitative and quantitative evaluation of designs by identifying specific image schemas and product design features that have been positively or negatively received by the users. This allows user experience to be assessed in a systematic way, which leads to a better understanding of the value associated with particular design features.
