An operating input device for a vehicle and to a steering input device is disclosed. The operating input device has an upper part having an operating input surface with an input area associated with an operating function, and a lower part serving as a support structure for the upper part. The upper part is relatively movable to the lower part by an operating input force applied on the operating input surface in an operating input direction extending substantially perpendicular to the operating input surface. For generating a haptic feedback, the upper part and the lower part are coupled movably relative to each other such that by a feedback actuation mechanism, which is couplable to the operating input device, the upper part is movable relatively to the lower part at least in a first haptic feedback generating direction extending at least substantially parallel to the operating input surface.

Systems and methods are provided for ultrasonic haptic array devices. One embodiment of haptic array device includes a plurality of cells, each cell including a base and an array of ultrasonic transducer elements, and a support structure configured to independently position each cell.
