Benefit of inconvenience for ambient interface

Elaborating such convenient interface as ambient one has a risk to alter the base of human-machine interaction from natural phenomena to artificial contracts. On the other hand, examining benefits that are frequently observed from “inconvenient” tools or method reveals a notion that human-machine interaction is originally governed by physics rather than contracts between designers and users. This notion is generally taken to be trivial and is ignored, but in the case of elaborating ambient interface, it is essential to accumulate notions of interactions observed from what are originally ambient, i.e., being governed by physical laws. This paper discusses how the standpoint of appreciating benefits of inconvenience contribute to ambient interface.
