Values in action (ViA)

The shift in HCI towards emotions, values, needs etc., (third-wave HCI) reflects the new understanding of interactions between users and technology. However, the focus on usability in the first-wave slightly got out of sight in the second-wave, which mainly addressed the user in working environments, and even more in the third-wave HCI. This wave holds a focus on emotions, experiences and values, not only at work but also during leisure time. We have identified a lack of suitable frameworks and concepts, which provide an integrated view on values on the one hand and usability, user experience and user acceptance on the other hand. For evaluating a prototype in an Ambient Assisted Living project we developed an approach for combining value- and user-centered design with factors related to usability, user experience and user acceptance.
