Control flow for the FIMP. Subject starts walking in the FIMP. RealSense camera detects the user’s position and drives the wheels to follow the subject. As the FIMP follows the subject, it polls a “fall button” used by the investigator to signal his/her intention to trip the subject. When the button is depressed, the gait phase detection algorithm is run to detect the appropriate time to trigger the fall inducing mechanism for the pre-selected fall type. When the subject enters the desired gait phase, the fall inducing mechanism is activated as the FIMP is simultaneously brought to a stop. Subjects are instructed to recover and stand straight after the trip
