Abstract:
An actuation device comprising:a support frame; first, second third and fourth linkages, each having first and second spaced apart portions, the first portions of the first and second linkages being secured to the support frame for pivotal movement about first and second spaced apart pivot axes, respectively, and for rotational movement about a common first rotation axis transverse to the first and second pivot axes, the first portions of the third and fourth linkages being secured to the second portions of the first and second linkages for pivotal movement about third and fourth pivot axes, respectively, the second portions of the third and fourth linkages being secured to one another for pivotal movement about a fifth pivot axis; a user interface component secured to the second portion of one of the third linkage and the fourth linkage, the user interface component having a surface shaped for contact by a body part of a person; and a first rotation actuator having a first rotation actuator body and a first rotation actuating component secured to the first rotation actuator body, the first rotation actuator being connected between the frame and the first linkage such that movement of the first rotation actuating component causes rotation of the first, second, third, and fourth linkages about the first rotation axis.
