Virtual Touch
This installation's user interface may look plain and simple, but its astounding features are brought out by touching "Virtual Touch". With the index finger and a "thimble," a point in three-dimensional space can be moved on the monitor screen. If you maneuver the point within a rectangular figure and attempt to lift it up, you experiences a small miracle—the thimble-mouse encounters palpable resistance. "Tactile feedback" is the technical term used to characterize the process whereby virtual objects take on physical properties.
