A rare piece of writing from Durrell Bishop:
What if there was a generic tool to link the digital and the physical worlds? A way to touch an object, to select and see its digital augmentation? It would just send a message via your chosen device: laptop, mobile, home wifi et al. The equivalent of a digital finger. Passive objects would act as physical buttons to the digital world. All that these objects would require is that we perceive their purpose, and see how to act on them. We would need to have an accessible tool to make our selection, and carry out the link between the two worlds.
