<p>Sensor systems for detecting the position and/or trajectory of an object as well as their methods of use are disclosed. In one embodiment, a sensor system may include three or more parallel conductors adapted to be arranged on a ball playing surface. The three or more conductors may be adapted to detect an electrical signal induced in at least two of the three or more conductors by a ball. The sensor system may also include a processor electrically communicating with the three or more conductors that is configured to receive the electrical signal and output at least one of a trajectory and position of the ball.</p>
