In the recent test series between India and England, Star Sports, which is the official broadcaster in the Indian sub-continent, showed a new graphics after each ball is bowled. It was the amount of ball swing(in-swing/out-swing). The data was in centimetres & the measuring axis was the trajectory of the ball if it doesn't undergo any swing.
So, what new technology was used to measure this deviation? Or was it just the good old Hawk-eye with some data processing?
