  3. 3. WHY IT IS USED ? The Hawk-eye referral for LBW decision in Cricket is based on three criteria: • Where the ball pitched • The location of impact with the leg of the batsman • The projected path of the ball past the batsman
  4. 4. INTRODUCTION • Hawk-Eye is a computer system used in cricket, tennis and other sports to track the path of the ball. Six cameras tracks the ball so 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.
  5. 5. HISTORY • Developed by engineers at Roke Manor Research Limited ,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.
  6. 6. HOW IT WORKS
  8. 8. ACCURACY OF THE TECHNOLOGY During ITF testing in 2006 Hawk-Eye made the correct call in 100% of all tests, showing an average error of only 3.6mm. Tests have always been conducted outdoors, encompassing situations that take the following factors into consideration: 1. Wind (and therefore camera wobble); 2. Bright sunlight at different times of the day; 3. Shadows covering part or the majority of the court; 4. Dark or overcast conditions; 5. Artificial floodlights.
  9. 9. 6. Indoor venues are obviously easier as compared to Outdoor ; in indoor easy to track because conditions are far less variable. Quite simply, Hawk-Eye can track accurately and reliable in any conditions, on any surface. 7. Although the accuracy of the existing system has been tried and tested, the company is constantly trying to develop and refine the system. Hawk-Eye listens to feedback from customers and officials to ensure that Hawk-Eye remains the very best in the market.
  10. 10. APPLICATIONS 1. It finds its application in different games like Cricket, Tennis and Snooker. 2. It has also been implemented in computer games to give reality to the game. 3. It is basically used in Cricket for giving LBW decisions.
  11. 11. 4. It is used in tennis for making line calls. 5. It is used in snooker for producing players line of view, shadowed area and blue dot.
  12. 12. FURTHER DEVELOPMENTS 1. Hawk-Eye is already working on implementing a system for basketball. 2. The Football Association has declared the system as "ready for inspection by FIFA", after tests suggested that the results of a goal-line incident could be relayed to the match referee within half-a-second (IFAB, the governing body for the Laws of the game, insists on goals being signaled immediately e.g. within five seconds).
  13. 13. DISADVANTAGE • Cost : It would cost around at least £500,000 to have all the technology equipment needed. • Referee loses power: Players may lose respect for the referee if he is constantly being proven wrong. • Time Consuming: During taking review it is very time consuming which takes up playing time.
  14. 14. CONCLUSION • After all the test that have been conducted on this technology , it has always come out successful and it promises to be a boon for the world of sports and now it is up to the different councils to decide whether to use this technology or not…….
