A system for detecting the position of a person in a pool (2), comprises a transmitter positioned in the pool (2), a receiver (20) for receiving the signal from the transmitter (16a-16f) and generating a stimulus, with the receiver (20) being positioned on the person. The pool (2) may contain a lap lane (4) and a series of transmitters (18a-18f) traverses the center of the lap lane. The receiver (20) may comprise a disc member with a suction means for attaching to a person. In another embodiment, the transmitter and the receiver are configured as a single unit (42). A method of detecting the position of the swimmer within a pool includes placing the person within the lap lane (6) and allowing the person to advance within the lap lane (6). A signal is transmitted from a transmitter (16) and the signal is received. In response to the received signal, a first tactile stimulus is generated which is felt by the person. This tactile stimulus indicates to the person that he/she is on course. In the event that the tactile stimulus is no longer sensed, the method may further comprise altering the course that the person is transverse within the lap lane (6). The signal from the transmitter (16a-16f) located on the bottom of the pool (2) continues to transmit a signal which in turn said signal is received once the receiver is positioned above the transmitter (16). |
