Casting Doubt On the Hawkeye Ball-Calling System
Human judgment by referees is increasingly being supplemented (and sometimes overridden) by computerized observation systems. nuke-alwin writes "It is obvious that any model is only as accurate as the data in it, and technologies such as Hawkeye can never remove all doubt about the position of a ball. Wimbledon appears to accept the Hawkeye prediction as absolute, but researchers at Cardiff University will soon publish a paper disputing the accuracy of the system."
And ultra-accurate GPS like system that tracks the position of balls in nanosecond detail. They can call it Your Object Universal Remote Movement Observance Mechanism, or YOUR MOM for short.

You're a guy reading slashdot by yourself on a saturday night. It doesn't take any special technology to know the answer to that question.
Just put high-powered lasers firing down the lines. If the ball is melted slag, it was out.
Army brat, myself, but my first thought on reading the headline was along similar lines.
I couldn't for the life of me think of a reason why a Hawkeye would need a system to call the ball when every other pilot in the Navy has to do it with the ol' Mk. 1 Eyeball.
End of line..
They have already experimented with this idea, but had problems keeping the sharks under control.
Have a look at soylentnews.org for a different view
Yes, some people also want to use Hawkeye for some decisions in cricket, the sport that first used it. However the margin of error is far greater (approximately +- 2 inches) in cricket as the cameras have to be a lot further away due to the size of the pitch.
Also Hawkeye finds it hard to pick up swinging, seaming and spinning balls. Basically anything that deviates off its theoretical trajectory either in the air or off the playing surface. Both of which are vital in the LBW decisions where the TV companies and doubtless the Hawkeye people would want to see it used.
Obviously cricket is a far more useful game than tennis so does this answer your question?

If this were really happening, what would you think?
This assumes there is another method, such as post-analysis of videotape, that can find almost all uncorrected errors or at least give some good indication of the uncorrected error rate.
Another method would be to use Radar instead of Hawkeye. Probably faster and more efficient as well.

Yeah i hear they invented something like this : every time the ball touches the grounds it leaves a visible mark. i think they call it Complex Layer Against Yelling, but i doubt Wimbledon and its tradition are ready to take the plunge
In the event of a tie between the two systems, perhaps a Honeycut system to break the tie.
Government's idea of a balanced budget: take money from the right pocket to balance...oh who am I kidding?
You Pierce me with your wit! It Burns! When you finally drag out your Winchester and kill me, you'll have to bury me in a field fit for a Potter because I can't afford anything better.

That ball was on the line!
