This paper presents the cybercarpet, an advanced model of a 2D locomotion interface with high velocities and high accuracy. The cybercarpet consists of an array of balls which are actuated by a belt mounted on a turntable. The goal is to keep the walker in the center of the platform while he performs arbitrary motions in the virtual environment. The current approach is based on mechanical principles and components which could also be used for a big scale platform. Moreover the findings presented in this work are judged with respect to upscalability.
