Hidden computing (sometimes called unconscious computing) is one of the most exciting future applications for Bluetooth technology. While not directly addressed in the version 1.0 specification, hidden computing has been discussed at SIG events in the past and is an area ripe for future exploration. The fundamental elements required for some forms of hidden computing already exist in the current specification, although the SIG has not developed profiles that describe how the various hidden computing applications might be accomplished in a standard and interoperable manner.

Hidden computing involves a class of applications in which devices that are not overtly being used by a person can still perform tasks on that person's behalf. We have already seen one example that could be considered a hidden computing application: the automatic synchronizer. In that usage model, a PDA "hidden" in a pocket or purse could synchronize with another device without user intervention. Several other examples have been described in the context of Bluetooth wireless communication. Among these are:
