Hands-on Values: A Value-based Evaluation

In order to evaluate prototypes, which aim at fostering elderly’s social interactions, we tried to find an approach that not only accounts for values, but also for usability, acceptance and experience factors addressing the interaction between users via the technology. Despite a variety of value-based approaches in HCI for the development of technologies, we faced a lack of practical frameworks, which consider those usability, user acceptance and user experience factors. We finally encountered the theory of consumption values, which predefines five values, i.e. the conditional, the functional, the emotional, the epistemic and the social value. After adding a further interpersonal value the approach is able to encompass those factors for evaluation purposes.
