Disney can now track your laughter, smiles, gasps, and frowns inside those darkened cinemas.

The media conglomerate’s research arm is using machine learning to assess the audience’s reactions to films based on their facial expressions, it wrote in a new research paper (pdf). It uses something called factorized variational auto-encoders, or FVAEs, to predict how a viewer will react to the rest of a film after tracking their facial expressions for a few minutes.

The FVAEs learn a set of facial expressions, such as smiles and laughter, from the audience, and then make correlations between audience members to see if a movie is getting laughs or other reactions when it should be—a much more sophisticated version of how Amazon and Netflix make suggestions for new things to buy or watch based on your shopping or viewing history.
