Have you ever watched a film and wished the direction in which it is going would change?

Well, a new brain-controlled movie has now been launched, which picks up reactions from the viewer via an electroencephalogram (EEG) headset and switches the storyline depending on their response.

The film, called 'The Moment', has been developed by the University of Nottingham's computer science PhD researcher and creative director Richard Ramchurn.

It is being officially launched at Sheffield Doc/Fest on June 7.

From there it will tour the country in a specially adapted caravan that has been transformed into a mobile cinema.

An EEG is a recording of brain activity. During the film, viewers will wear small sensors attached to the scalp to pick up the electrical signals produced when brain cells send messages to each other.

As people watch the film small drops in attention will alter the signals and trigger a change in the story.

The film’s story is based around two main characters who are taking refuge from a society which uses brain control technology.

The film shows how the characters don’t fit in and their fight for survival as outcasts and takes inspiration from refugee stories both in film and reality.

Mr Ramchurn said: "The Moment is an interactive film which is controlled via data from a EEG headset which picks up unconscious reactions and changes the narrative thread in response.

"The story explores three narrative threads in a dystopian future world in which brain-computer interfaces are both a source of social threat and potential revelation. As a piece of science fiction the film speaks about the present. Our relationship with each other via social media and the facilitation of rise of far right ideologies."

The Moment is different each time it is watched, as the media adapts to the viewers attention levels, when the system detects a drop in attention it will cut to another narrative thread. Each scene has a possible of six combinations.

Her added: "Where the viewer has a lot of variance in their attention the film will cut quickly between the primary and secondary narrative threads, if the viewer sees more of the primary thread the next scene will remain in the same combination, if however, they see more of the secondary thread the next scene will replace the primary thread with the unseen thread.

"The intention of making this work now, is to study how people react to the trend of real-time personalisation and the myriad of possible recombinations.

"This platform will allow us to study interactions with a system that allows for passive interactivity, and how that can be used to produce narrative work, add value and encourage multiple viewings."
