The first wearable computing device comes from Edward O. Thorp and Claude Shannon – better known as the fathers of card counting theory and information theory. In 1961, the two sat down and built an analog computer in cigarette pack size, which should predict the outcome of roulette games.
The wearer controlled the device via microswitch in his shoe, and the device reported to the user via music tones sent to an in-ear radio receiver. Although successfully tested, hardware issues prevented the unit from being used regularly at the tables. Over the next two decades, technological advances would lead to a multitude of entrepreneurs manufacturing shoe-based computers to outsmart the casinos.
