Tracking and behavior classification of flies with Flyworld and Flytracker.
(A) Schematics of Flyworld, with camera, illumination system, and walking arena. (B-D) Example trajectories of different numbers (1, 16 and 50) of male flies tracked by Flytracker. (E) A touch event where one fly’s head approaches another’s tail in darkness, recorded with an infrared camera. (F) Adjacency matrix of touch behaviors. Colors represent frequencies of touch behavior. Mathematically, no self-interaction was defined.
