Method and system for performing linear and circular movement patterns

A linear and circular movement system, comprising a limb-activated, linearly and circularly moveable apparatus comprising:

• i) a gripping device adapted for gripping by a limb;
• ii) a rotatable platform connected to the gripping device, the platform being rotatable by a first movement of the limb with the limb gripping the gripping device;
• iii) a pivoting element connected to said platform;
• and
• iv) a sliding base connected to said pivoting element, the base being removable from the apparatus, the base comprising a low friction coefficient bottom surface, the base being smoothly slideable across a contacted surface in contact with the bottom surface, the sliding base in contact with the contacted surface having a friction coefficient permitting the sliding when a person presses the apparatus at an oblique angle, the base being slideable by a second movement of the limb with the limb gripping the gripping device,
• wherein the system comprises a plurality of removable sliding bases, each base providing a different coefficient of friction with the contacted surface,
• wherein the first and second movements of the limb with the limb gripping the gripping device actuates the platform and base to realize both linear and circular motion of the apparatus with respect to the contacted surface.
