Points of interaction and engagement with technologies could as well be vanishing points. Where technologies and systems recede from attention. This is the theme of the chapter Vanishing Points in the Mundania-book. It starts like this:
Devices, gadgets and everyday things might be the most obvious tangible entities of Mundania. Present technology. Perceivable and touchable. But what does it mean that something is tangible, and for whom and when is it tangible or graspable? How can different aspects of technologies be controlled in Mundania, and by whom? What do different people have to know about the technologies they live with? What can they know? The aim of this chapter is to approach these questions by closely engaging with some of the devices, materials and details of Mundania, and to start thinking about how they often seem to vanish.
