Hawk-eye is a program that allows people to view where tennis balls land after they are hit in matches. Good tennis players hit the ball fast- about 120 MPH- which means the ball can pass a length of two cars in the time it takes to blink. Because the balls move very fast across the court, it is hard to tell if a ball is in or out when it touches the line.http://www.hawkeyeinnovations.co.uk/
