The human body, evolved for Earth, naturally controls movement using gravity and friction. In space's zero-gravity, this physical basis vanishes, causing intrinsic difficulties in balance and motion control. To overcome this, the 'Tail Device' is proposed. Inspired by the paradox that the tail—a degenerated human feature—is now necessary for weightlessness, this wearable device aims to effectively control body balance and movement in outer space.
