Mobie: Movie Brain Interactive Editor

Interactive cinema is traditionally based on conscious operations (through buttons, joysticks, keyboards, voice, gestures). Plots created following the viewer’s state of mind would represent an interesting alternative. MOBIE is the first Movie Brain Interactive Editor enabling the creation of interactive movies from video sequences and real-time rendered animations, to be seamlessly arranged following the signals coming from a Brain-Computer Interface (BCI) worn by the viewer.
MOBIE operates in Editor or Player mode. As Editor, it creates baseline titles, where special introductory video modules are designed to automatically calibrate the system to the viewer’s typical brain responses in the actual condition of movie viewing. As a Player, it allows viewers to watch videos interactively created during fruition. The current version of MOBIE has been developed in Flash and runs under both Windows and Mac OS X. As for BCI, the headset MindWave by Neurosky Inc. which is cost-affordable, easy to use and featuring wireless communication, acquires the alpha, beta, gamma, delta and theta brain waves and works out quantitative levels of attention and relaxation (as well as detecting eye blinking).
MOBIE is demonstrated by means of an original short movie based on an original novel (Borderlines, Bruno Riccò, 2010) and realized with Blender in 3D cel-shaded animation. The short movie is formed by an introductory branch (lasting 2 minutes) followed by two final ones (2 minutes each), to be alternatively chosen by means of the BCI. These modules correspond to different scenes, and through the BCI the viewer controls actual shots, camera movements, depth of field and narration jumps. The system can be easily adapted for other applications, such as video games, learning and infotainment.
