  2. 2.  The world of sport is continually changing over the years, and the use of technology is just one of those areas that has made an impact on many sports in the modern day.  One criticism of the use of technology is that it can slow down the speed of the game. Do you agree?
  3. 3.  Most professional sports in the United States have long used instant replay and other high-tech aids to help referees make the right call. ◦ Gridiron has used video replay systems to check referees' calls for many years.
  4. 4.  Basketball referees use replay systems to make sure players are shooting within the time allotted by the shot clock.
  5. 5.  In international cricket, the third umpire has been used, one sitting off the ground with access to TV replays of certain situations (such as disputed catches and boundaries) to advise the central umpires.  The umpires out on the field are in communication via wireless technology with the other umpire.  The third umpire is also asked to adjudicate on run out decisions, which he makes without consultation with the two central umpires.
  6. 6.  One sport that has resisted the use of high- tech assistance is soccer/football.  Replays could be used to decide off-side decisions, whether a ball passes over the goal line, and clarify penalty decisions  Do you think football would benefit from introduced technology?
  7. 7.  There has been a need for goal line technology in soccer, particularly as TV replays are showing in retrospect wrong decisions by the referee.  The International Football Association Board (IFAB) has laid down four criteria that they want to see in goal-line systems: ◦ The technology should only apply to goal-line decisions. ◦ The system must be 100 per cent accurate. ◦ The signal sent to the referee must be instantaneous. ◦ The signal is only communicated to the match officials

  10. 10.  Hawk-eye is the name of a computer and camera system which traces a ball's trajectory.  It is being used in international cricket and tennis, and many other sports are also looking at making use of this technology.  The system is also being trailed in soccer.
  11. 11.  The Premier League of Football in the UK has agreed to the introduction of goal-line sensors after being given approval by football's rule- makers.  The system being developed by the UK company Hawk-Eye, would give a definitive decision on whether the ball had crossed the line.  The Hawk Eye uses a camera taking 600 frames a second on the goal-line.  The information is analyzed by computer and sent to the referee's headset or a device on his wrist.

  14. 14.  In groups discuss the pro’s and con’s for the introduction of Goal Line Technology in Soccer.  What other scenarios could technology be introduced into the game of soccer? ◦ Will these introductions be beneficial or detrimental? ◦ What sacrifices will the sport make to introduce more tech?
