1. A haptic device comprising:

  • at least five axially moving struts, together forming a parallel link mechanism, each strut having a first end and a second end;

    a frame comprising a plurality of brake nodes, each mounted in ball-and-socket manner in the frame, each brake node constraining axial movement of at least one of said struts that passes by sliding movement through the brake node;

    a haptic stylus supported by each second end of each said strut;

    wherein the struts pass through said brake nodes with sliding axial movement and wherein force feedback is effected by proportional control of brakes in the brake nodes, constraining sliding axial movement of the struts through their corresponding brake nodes, and wherein the haptic stylus moves with at least five degrees of freedom and gives force feedback in three dimensions.
