Abstract
A track type impact buffered input device is equipped with an extra weight buffer. When the input device is moved from a position to another by the user, the weight buffer will retard the motion of the input device with its increased inertia as if a reversed force were applied to the input device. Hence, the impact force imposed on the user's wrist is alleviated by the retarding effect of the weight buffer, and the user does not need to exert a large force to stop the input device at the new position or when a sudden change of moving direction is required, thereby preventing potential injury to the user's wrist by the impact force.
