A touch interface device includes a touch surface configured to be engaged by an object, first and second actuator assemblies operably connected to the touch surface, and a controller operably connected with the first and second actuator assemblies. The first actuator assembly displaces the touch surface in one or more lateral directions along the touch surface at a first frequency. The second actuator assembly displaces the touch surface in an angled direction that is one of at least obliquely or perpendicularly angled to the touch surface at a second frequency. The controller operates the first and second actuator assemblies so that the touch surface varies in engagement with the object to impart a force on the object that is along the touch surface.
