It's an "action film for the mind". That's the pitch. To promote new sci-fi movie MindGamers, someone thought it would be a good idea to strap a thousand audience members into "cognitive bands". Tying into the movie's debut, the bands will let researchers monitor and record the state of the audience's mind simultaneously during the feature, resulting in a "mass-mind state" image of everyone's feelings and brain activity. Details are thin on exactly what's being monitored, although the screening is bookended by introductory talks and Q and As from experts in neuroscience technology. That may help to distract from having to wear a headband throughout the entire feature.
