Hawk-Eye
Digital line judge
Hawk-Eye is a ball-tracking technology used in tennis, cricket, and other sports to determine whether a ball landed in or out of bounds.
The system uses multiple cameras to reconstruct the ball's trajectory and display it graphically, often for official review of disputed calls: The umpire went to Hawk-Eye to check the line call.
Players may challenge rulings by requesting Hawk-Eye review.
