Hawk-Eye is a computer system used in cricket, tennis and other sports to track the path of the ball. It was developed by engineers at Roke Manor Research Limited in 2001; the patent being held by Paul Hawkins and David Sherry. Later, the technology was spun off into a separate company, Hawk-Eye Innovations Ltd., as a joint venture with television production company Sunset + Vine.
Its major use in cricket is in analysing leg before wicket decisions, where the likely path of the ball can be projected forward, through the batsman's legs, to see if it would have hit the wicket. Currently this information is only visible to television viewers, although it may be adopted in the future by the third umpire, who currently sees only conventional slow motion replays. Consultation of the third umpire on leg before wicket decisions is not currently sanctioned in international cricket and doubts remain about its accuracy in cricket.
Due to its realtime coverage of bowling speed, the systems are also used to show patterns of bowling in a bowler's behaviour. At the end of an over, all six deliveries are often shown simultaneously to show a bowler's variations, such as slower deliveries, bouncers and leg-cutters. A complete record of a bowler can also be shown over the course of a match.
Batsmen also benefit from the analysis of Hawk-Eye, as a record can be brought up of the deliveries batsmen scored from. These are often shown as a 2-D silhouetted figure of a batter and colour-coded dots of the balls faced by the batsman.
Hawk-Eye has a couple of other useful features. Because of the six cameras tracking the ball, Hawk-Eye picks up the exact spot where the ball pitches. Hawk-Eye also measures the speed of the ball from the bowler's hand, so it will tell you exactly how much time the batsman has to react to a ball.
