The experience of computer use can be productively articulated with concepts developed in the phenomenological tradition of philosophy. Building on the insights of classical phenomenologists, Ihde has advanced a sophisticated view of the ways humans relate to technology. I review and expand on his notions of “technological mediation,” “embodiment,” and “multistability,” and apply them to the experience of computer interface. In particular, I explore the experience of using a computer that fails to work properly. A revealing example is the experience (...) of a user who suddenly and unexpectedly encounters a slowly-loading webpage while using the Internet. This phenomenological framework provides an account of the ways a suddenly failing technology changes our relationships to the device, to the world, and to ourselves, and it also suggests how this experience can be usefully reconceptualized.
