An electronic line judge is a device used in tennis to automatically detect where a ball has landed on the court. Attempts to revolutionize tennis officiating and the judging of calls in the sport began in the early 1970s and has resulted in the design, development and prototyping of several computerized, electronic line-judge devices. The methods have been based upon the use of pressure sensors, sensors to detect magnetized or electrically conductive tennis balls, infrared laser beams, and most recently video cameras.
