Abstract
System, method and device to generate user tactile feedback using working fluid inside a sealed vessel, which is vaporized causing a rapid pressure/volume change, then the fluid condenses, restoring original pressure/volume. In one embodiment this sequence is repeated to create a vibration. The sealed vessel is mechanically coupled to a touch surface so the user feels the vibration, typically with a fingertip. In some embodiments a portion of the sealed vessel is also the touch surface. In some embodiments multiple vessels are arranged in an array behind or integral to the touch surfaces.
