Abstract
According to one aspect of the invention an actuation device is provided which includes a support frame first, second, third, and fourth linkages, a user interface component, and a first rotation actuator. Each linkage has first and second spaced apart portions. The first portions of the first and second linkages are secured to the support frame for pivotal movement about first and second spaced apart 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 are 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 are secured to one another for pivotal movement about a fifth pivot axis. The user interface component is secured to the second portion of one of the third linkage and the fourth linkage. The user interface component has a surface shaped for contact by a body part of a person. The rotation actuator has a first rotation actuator body and a first rotation actuating component secured to the first rotation actuator body an…
