A recurrent theme of human–machine interaction is how interaction is defined and what kind of information is relevant for successful communication. In accordance with the theoretical strategies of social cognition and technical philosophy, we propose a pragmatic interactive approach, to understand the concept of information in human–machine interaction. We start with the investigation of interpersonal interaction and human–machine interaction by concerning triangulation as guiding principle. To illustrate human–machine interaction, we will mainly focus on the interactive relationship between human cognitive skills and their technological environments. In triadic interaction, the concept of information cannot only be understood as a syntactic transformation as in the dyadic relationship. We argue that information as pragmatic action patterns can be understood as physically embodied units that is not purely formal but generated in interactive processes and stabilized in use. By exploring how the concept of affordance is applied in psychology, anthropology and human-centered design, we provide a notion of pragmatic information, focusing on users in the development and use of machines or software systems. The triadic interaction of end user, development team, and product leads to a successful human–machine interaction. This theoretical framework enables us to understand how the new socio-technological environments expand our scope of action and how we form, interpret, and learn to deal with patterns of action among ourselves and with machines.
