A tactile device for correcting biomechanical abnormalities using physical virtual reality simulations includes an outer hollow sphere, a pliable inner hollow sphere, a plurality of actuators, and a framework. The plurality of actuators physically couple the outer hollow sphere to the pliable inner hollow sphere, and are configured to reshape the pliable inner hollow sphere as the outer hollow sphere and the pliable inner hollow sphere rotate. The framework includes a plurality of powered rollers which support the outer hollow sphere and control a rotational speed and direction of the outer and inner spheres. A set of pressure sensors detect pressure applied by a user against the pliable inner hollow sphere as the user moves within. One or more processors determine a biomechanical abnormality in the user based on pressure readings from the pressure sensors. A sphere controller then modifies a physical configuration of the pliable inner hollow sphere.
