Hawk-Eye on the Prize and the Goal

One thing was proven at this year’s World Cup tournament: you need to have eyes like a hawk to keep track of the ball. That’s why Dr. Paul Hawkin, inventor of Hawk-Eye, is pushing for adopting of his tracking system by the International Football Association Board. If adopted this could see the use of goal-line watching technology put in place this year.

Hawkins isn’t new to the world of sports either, and he previously developed the ball-tracking device used in cricket, snooker and tennis, and is pushing for similar technology to be used in football/soccer. The system includes six cameras facing the goal from different angles to track the ball, where a signal is transmitted via a bank of computers to a referee with half a second of the ball crossing the line. Given some of the disputed calls during the World Cup, this could make a huge difference.

However, not all are in embracing the idea. It has been noted that many English Premier League matches are carried by Sky TV, which has eight cameras on the field, so a simple replay should often be enough to determine a call. But the real question is whether you can ever really have enough eyes – Hawk – or otherwise watching the action?

Air Ball

adidas World Cup Jabulani Ball

This week the California Institute of Technology gave new meaning to the concept of “air ball” as aerospace engineers at the prestigious school put the controversial new “Jabulani” football (that’s soccer to most of us Americans) to the test in a wind tunnel. The ball, which was developed by adidas, is currently being used in the World Cup, where players, coaches and fans have blamed it for missed shots. So much for blaming bad play?

According to reports two balls were put into the Lucas Wind Tunnel and exposed to wind speeds of about 10 meters per second, which is actually slower than a typical kicked ball. To determine the movement of air around said balls, a smoke machine was called in. This helped the engineers visualize the air movement. The findings actually matched some complaints from teams in the World Cup. The ball reportedly had some “bizarre trajectories.”

 Developed by the adidas Innovation Team (a.i.t.), the ball has been tested as new “match ball” for the 2010 FIFA World Cup in South Africa. This mean tests under the toughest laboratory conditions, but it isn’t clear if this is in fact the first time the ball went into a wind tunnel. At this point it doesn’t look as if the ball will pulled, but with more studies coming dare we say that the wind of change is blowing through.
