Abstract
An active user interface assembly includes a user interface, and one or more feedback motors coupled to the user interface. The one or more feedback motors, when energized, supply a feedback force to the user interface that opposes user interface movement. One of the feedback motors is disposed such that its center of gravity is located at a position relative to the user interface to mass balance the user interface when it is in the null position. The configurations allow for the center of gravity of a feedback motor to be positioned in a manner that alleviates the need for counterbalance weights.
