Man vs Machine is a performance installation collaboration created by Matthew Allen & Jack Ratcliffe. In this piece the audience is invited to physically interact with a performer connected to the piece through brainwave, pulse rate, temperature, movement and galvanic skin response (lie detector) sensors.The performer’s body naturally reacts to the audience inputs, and it is these natural biological responses that are recorded by the sensors and visualized behind him for the audience to see.

The piece explores theorist Marshall McLuhan’s idea that modern technology had outer-ed the brain and nervous system from existing purely within the human body. This still-accelerating process of humans “outsourcing” physical and mental functions has accelerated with the rise of digital technology, and thus continues to produce huge cognitive changes.
But one barrier strongly remains between humanity and its technology: physical bodies.Through the interactions of the audience, the installation merges the physical attributes of the human and the computer, generating a visualisation which highlights the human body as the ultimate interface – and the ultimate barrier – for human-computer interaction.

Man vs Machine uses five sensors to read the biorhythms from the human performed – brainwave, pulse rate, temperature, galvanic skin response and movement. It passes these readings through an Arduino and feeds them into an OpenFrameworks script that generates the 3D visualization projected from behind the performer.
The difference in which factors affect which elements produces an interesting juxtaposition: the human's readings can be altered by emotional changes, environmental shifts and countless other factors, involuntarily shifting the body's outputs. 

The computer, on the other hand, is insusceptible to such subtleties, but benefits from direct control of it's temperature regulation system in response to heighten interactions. Equally, the human and the machine perceive common experiences in incredibly divergent ways. Watching relaxing or shocking video on the computer would have hugely differing effects on the human, while the computer will respond identically to experiencing both: simply by increasing it's processing output.
