Technology, Interface, Enaction

Yet...

In Enaction and Engineering, John Stewart, Armen Khatchatourov and Charles Lenay argue that all technical artefacts are enactive interfaces. They mediate between human beings and the world they live in. In so doing, they bring forth a particular world of lived experience. Stewart et al. make it clear that it is not the interface that is enactive. It is the person, using an appropriate, well-designed interface, who enacts a world. This leads to a recognition of the crucial role of interfaces, in other words technical artefacts or technologies: while they allow people to enact a world, they may also inhibit such enaction. The world in which people live is vitally affected by the design of such interfaces, artefacts or technologies.

Stewart et al. provide a useful three-part categorisation of technical artefacts: extensions of the body, such as devices, tools and instruments; modifications of the environment, such as roads, buildings and fields; and semiotic artefacts, such as languages, codes and pictures. In practice, however, technical artefacts are not isolated from one another but form technical systems, or rather socio-technical systems, with synergistic interactions among the different types of artefact. Choices of technological devices and systems enable the construction of the worlds that people live in, in being interfaces that change the means of action and of experience.
