Abstract
A navigation control apparatus, such as used to control a cursor on a display of an IP telephone, has a geometry that allows a user to produce a diagonal motion of the cursor displayed on the IP telephone. The navigation control apparatus has a support mount having navigation contact terminals and navigation actuators aligned with the navigation contact terminals, each navigation actuator configured to form an electrical contact with each of the contact terminals. Each navigation actuator and contact terminal defines a travel distance for each navigation actuator. The navigation control apparatus has a hemispherical navigation controller pivot coupled to the support mount. A navigation controller actuates the navigation actuators and defines rounded recess that engages and rotates about the navigation controller pivot during an actuation procedure. The rounded recess of the navigation controller and the hemispherical shape of the navigation controller pivot define a navigation controller travel distance that is approximately one-half the travel distance of each navigation actuator.
