ABSTRACT
In the late 1900s the world of sports went through an era of controversies where erroneous decisions made the difference between a win and a loss. Technology was a vast and effective resource that needed to be tapped but nobody had the know-how on how to harness this resource.
The new millennium brought with it a breakthrough, a revelation in this field. The year 2001 saw the birth of a phenomenon which the world soon came to know as HAWK-EYE. Along with the birth of new technology comes a series of questions that I will answer.
What is it?
How does it work?
Where can it be applied?
What is its future scope?
What are its limitations?
Can these limitations be overcome?
Hawk-Eye is a complex computer system used in cricket, tennis and other sports to visually track the path of the ball and display a record of its most statistically likely path as a moving image. In some sports, like tennis, it is now part of the adjudication process. It is also used in some instances to predict the future path of a ball in cricket.
All Hawk-Eye systems are based on the principles of triangulation using the visual images and timing data provided by at least four high-speed video cameras located at different locations and angles around the area of play.
