Important Facts �First invented by Dr. Paul Hawkins in 2001. �Extremely complex computer system �Costs around $20, 000 -$25, 000 per court for one week �Hawk-Eye is not featured at over 60 events across the ATP, WTA , and ITF tours

How Does it Work? � 10 high-speed cameras at different angles and positions around the court �Creates a 3 D trajectory of the path of the ball �Uses the 3 D trajectory to determine the exact touch area the ball made with the court when it bounced

Results �Exact bounce mark is determined and shown via virtual software �Using the triangulation of images from cameras players can see exactly whether the ball was in or out �Only a 3. 6 mm margin of error

Example

Is it really necessary? �“The ball's moving so fast these days that sometimes it's impossible for anyone to see, even a trained official. With instant replay we can take advantage of technology and eliminate human error. Having just a few challenges will make it both fun and dramatic for fans at the same time. ”

Player Rules �Each player is allowed 3 unsuccessful challenges per set �If the set reaches a tie-breaker, each player is awarded 1 extra challenge �If the player’s challenge is unsuccessful, then the player loses that challenge.

Added Benefits �Can measure speed of the ball at any point during a rally �Service patterns, length ran during rally, service comparisons, and percentage of time a player spends in different regions of court
