This presentation discusses Hawk-Eye, a computer system that visually tracks the path of a ball in sports like cricket and tennis. It uses high-speed video cameras placed around the field and the principle of triangulation to analyze the ball's trajectory. Some key applications of Hawk-Eye include providing data for LBW decisions in cricket, creating pitch maps and wagon wheels. While an advanced technology, it is also expensive and not completely accurate. Future work aims to improve Hawk-Eye's cost effectiveness and develop it for other sports.

3. Hawk-Eye is a computer system used
in cricket, tennis, snookers 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
Hawk-Eye as the most innovative technology provider
in sports broadcasting and is a development that will
reinforce the group's presence and influence.

4. • It is primarily used by the
majority of television
networks to track the
trajectory of balls in flight.
• It was developed by
engineers at Roke Manor
Research Limited of UK
in 2001
• A patent was submitted by
Dr Paul Hawkins and David
Sherry.

5. Hawk-eye can track
any type of bounce,
spin, swing and seam
movement of the ball.
Hawk-Eye is used for
referring decisions to
the third umpire in
LBW.

6. A Hawk-Eye system is
based on the principle
of ”Triangulation”
03/07/13 6

7. It is based on the
principles of
triangulation using the
visual images and
timing data provided by
high-speed video
cameras located at
different locations and
angles around the area
of play.

8. Its applications in cricket are
LBW decisions
Wagon Wheel
Pitch Maps
De-Spin

9.  One very common use of Hawk-Eye are the LBW
decisions, where the viewers can see the virtual
future path of the ball after it’s being pitched and in
conclusion get an idea of whether the batsman
should actually have been adjudged LBW or not.

10. The Wagon Wheel gives you an idea of the
different areas where the batsman has been
targeting to score singles, doubles, boundaries or
sixes.

11.  It is used to check the angle of turn or deviation of a
ball after it has pitched.

12.  This consists of a virtual map of the various areas of
the pitch where the bowler has bowled a delivery. It
shows you how consistent a bowler is, in terms of line
and length.

13.  This technology is being used in many sports
like cricket, tennis and snooker
 It is also a great tool which can be used by
players, statisticians, tacticians, coaches to
analyze previous games and come up with
strategies for subsequent ones.
It reduces the human efforts.
03/07/13 13

14.  It is highly expensive.
It is not 100% accurate.
It challenges the umpire decisions

15. This is one of the most advanced technology
being used in sports.
 It is also a great tool which can be used by
players, statisticians, tacticians, coaches to
analyze previous games and come up with
strategies for subsequent ones.

16. Hawk-Eye is currently developing a system for
football. If approved , it may be used in the 2014
FIFA World Cup
Hawk-Eye officials are working towards making
it more cost effective so that it can be used in
more premier tournaments around the world.
