Haptic technology handle radioactive substances. Since then, the use of force feedback has become more widespread in other kinds of teleoperators such as remote controlled underwater exploration devices. When such devices are simulated using a computer (as they are in operator training devices) it is useful to provide the force feedback that would be felt in actual operations. Since the objects being manipulated do not exist in a physical sense, the forces are generated using haptic (force generating) operator controls. Data representing touch sensations may be saved or played back using such haptic technologies. Haptic simulators are used in medical simulators and
Mystery of the Senses to be delivered in clumps that are hard to absorb". Ken Ringle of "The Washington Post" was not impressed, and described the series as "distracted, disorganized, frequently trivial and irritatingly self-indulgent". He went on to say that "instead of exploring our senses' role in the natural world", the programs "tends to celebrate instead the way corporations seduce them artificially for profit". Despite the mostly unfavorable review, Ringle did concede that "some moments in the series are pure gold". Mystery of the Senses Mystery of the Senses is a five-part "Nova" miniseries, based on the book "A Natural History of the
