A system for detecting the position of a person in a pool is disclosed. The system may comprise a transmitter positioned in the pool. Also included is a receptor for receiving the signal from the transmitter and generating a stimulus; with the receptor being positioned on the person. The pool may contain a lap lane and the series of transmitters traverses the center of the lap lane. According to the teachings of the present invention, the receiver may comprise a disc member with a suction means for attaching to the person. Alternatively, the receiver may comprise an elastic band member having operatively attached the receiving and generating means, with the elastic band being worn by the person. In another embodiment, the transmitter and receiver are configured as a single unit. A method of detecting the position of a swimmer within a pool is also disclosed. The method includes placing the person within the lap lane and allowing the person to advance within the lap lane. A signal is transmitted from a transmitter 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 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 traversing within the lap lane. The signal from the transmitter located on the bottom of the pool continues to transmit a signal which in turn said signal is received once the receiver is positioned above the transmitter. A second tactile stimulus is generated to the person in response to the signal reception. This indicates to the person that he is back on course. |
