Just listen to the voice on the phone. The voice tells you what to do. The voice says you're playing the lead in a movie. Hide in the toilets, find the getaway car, stake out the bank and take a deep breath. You're going in.
The description above is taken from Blast Theory’s website (Blast Theory, 2017), which describes their artwork, A Machine to See With. This is a pervasive game that involves a group of users following instructions on their mobile phones. As these instructions are spoken each user must carry them out, mobilising each individual participant across a real urban environment. Within a specific starting point in a city setting and at an arranged time, a participant’s phone will ring. The voice on the phone will then proceed to instruct a user about the fictitious bank robbery they are going on, leading them to real checkpoints and other participants before eventually reaching the doors of a public bank. The immersive fictionality of this experience relies upon the user obeying instructions through the technology of their mobile phone.
