Scrollbar and Touchpad with Tactile and/or Audible Feedback

A scrollbar or touchpad including a touch area and disposed on a flexible layer that is supported by a rigid substrate. The bottom surface of the flexible layer and the top surface of the substrate, eventually in combination with elements disposed therebetween are configured to provide a pattern of varying resistance to depression of the flexible layer. A user will feel the varying resistance to depression when moving a fingertip over the touch sensitive surface, thereby receiving tactile feedback. The elements disposed between the bottom surface of the flexible layer and the top surface of the substrate can be collapsible members such as collapsible domes or switches that produce a "click" sound when collapsing, thus providing both tactile and audible feedback to the user.
