A technique is provided for providing total flexibility of control of any desired operation within an environment where personnel work, such as an office suite. The location of transponders is determined by a location system. A user arbitrarily selects a convenient region for controlling an operation and the location system registers this in a memory. The location system then determines the position of each transducer and, when a transducer is within one of the selected regions, the location system responds by controlling the operation. For example, a region may be selected entirely arbitrarily so as to control room lighting.
