The cinema lab: brain activity tracked to find secret to creating immersive films

SMRTR summary

Researchers at the University of Bristol have built a cinema-lab that tracks brain activity, heart rate, and eye movements to measure exactly when audiences feel most engaged during a film. The technology was recently tested on a sci-fi short film called *Reno*, helping its director refine the final edit. Scientists hope the tool will encourage filmmakers to take more creative risks by reducing the financial uncertainty around bold storytelling.
