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
Five wits Five wits In the time of William Shakespeare, there were commonly reckoned to be five wits and five senses. The five wits were sometimes taken to be synonymous with the five senses, but were otherwise also known and regarded as the five inward wits, distinguishing them from the five senses, which were the five "outward" wits. Much of this conflation has resulted from changes in meaning. In Early Modern English, "wit" and "sense" overlapped in meaning. Both could mean a faculty of perception (although this sense dropped from the word "wit" during the 17th century). Thus "five wits" and "five
