US Patent 7175076 Cash dispensing automated banking machine user interface system and method

An automated banking machine is operative to enable users to operate the machine to carry out transactions such as the dispensing of cash. The exemplary machine provides audible instructions which are output through external loudspeakers, a headphone, or a handset. Rotation of a rotatable knob (372, 382) or other movable item causes the output of user selectable characters, transaction types and/or amounts corresponding to each respective position. The user selects the audible output produced in the current position of the knob for receipt by the machine as a transaction input by pressing on the knob. Characters and other selectable inputs corresponding to knob positions can be varied by the computer in the machine to reduce the risk of a criminal intercepting the user's inputs to the machine.
