The invention belongs to the technical field of training equipment and generally relates to a system for training and assessment of vestibular function and space orientation in personal rotation and movement. The system consists of a round ring, a support, a seat, a seat protecting device, a pedal A, a support top disc, a transmission rod, a supporting shaft casing, a supporting shaft, a photoelectric transmission control keyboard, a light emitter A, a photovoltaic converter A, a light emitter B, a photovoltaic converter B, a data processor and a display screen and can perform three axial movements including rolling, rotation and pitching, produce constantly-changing linear velocity and angular velocity, cognizing that an object performs axial rotation while enabling a user to conduct the three axial movements, axially separate a space reference system for direction cognition of the user, integrate main physiological organs (vestibule and eyes) with achieved space orientation and psychological activity process (space cognition) of people to be trained, thereby being capable of improving and analyzing the vestibular function and space orientation capability of the people engaged in complicated space activities and facilitating shortening of training course.
