    Only 2 challenges per match planned? Whereas tennis allows 2 challenges per game!

    And btw, that's 2 **incorrect** challenges... meaning if their challenge was correct in the challenger's favour, then they still have 2 unused challenges remaining.

    so, where are we? Is this going to happen?

    How about putting a 3D while playing back. Awesome isn't it.

    Also, BWF can also put a rule where if a call is made before 11 points. It should be considered as an interval. Hence, this should save the time. Too bad if it is called before point number 5. lol.

    For Badminton, I was hoping that each player can challenge two times per game (not per match). Maximum of 4 challenges in a game (if each side challenges twice).

    This will ensure players to challenge disputes over line calls not carelessly, Otherwise there would be too much delay in a match of 3 games.

    2 challenges for each player in a game is sufficient, IMO...

    What if they use some kind of laser guided lines? Once signal is broken, that is in or out. These should be very low on the floor and must be both in the line and outside the line. Whichever line breaks first, it is the indicator where the tip of the shuttlecock touch first. These need to be calibrated and certified. But its cheap and portable. The best thing is, the result is instant.



    Hmmm..... I should patent this. LOL

    Have you thought about a racket, a foot, or any part of the body can also break the laser guided signal?

    Yeah, implant RFID chips into the tip of the cork. Have a triangulated laser-tracking system follow the chip, and it sets off a signal when it touches the active-matrix Yonex mat. All corner-tips of outer perimeters are also likewise activated and in sync with the triangulation lasers.

    And set up a laser trip curtain over the net as well.

    And.... if the players try to take an unauthorised towel break, they get zapped...

    I thought about it. If the player wants to block the signal to make sure the call is in, be my guest. If the purpose is to delay, line judges will make the call. But the dispute is always when the shuttle is clear.

    Line judges are still needed. Don't be mistaken. BWF wouldn't dare to implement something too accurate. The line judges will be under a lot of pressure for wrong calls.

    RFID idea is too costly

    Wink Progress is moving very slowly at BWF

    .
    Hahaha... Even if the implant of RFID chips are put into the tips of tournament shuttlecocks, BWF might take years before they use this method of monitoring line calls.

    Slow progress is not a problem. Lack of progress is a problem.

    Whatever happens, badminton will get a challenge system before FIFA manages goal line tech. Comforting.

    Tennis has no limit on points, but we can take 7 per game x 13 games per set x 5 sets as a nominal maximum - 455. They get five challenges each in a five-setter. Badminton allows for 177 points across a three-set match, so I think three challenges each is slightly generous, if anything; two each is almost exactly equal to the tennis "ratio".

    Goal-line technology to be trialled in England friendly

    By Richard Conway BBC Sport
    Goal-line technology will be tested at Wembley when England host Belgium in a friendly on 2 June.
    Hawk-Eye, a camera-based system, will be used by independent testers during England's final game before Euro 2012.
    But the match officials will have no access to data and the trial will have no impact on any contentious goal-line decisions.
    The first live test of Hawk-Eye's system was conducted earlier this month in the Hampshire Senior Cup final.
    How does Hawk-Eye work?

    Hawk-Eye's system works by utilising six cameras per goal to track the ball on the pitch.
    The system's software then uses "triangulation" to pinpoint the exact location of the football.
    If the ball crosses the goal-line then an encrypted radio signal is sent to the referee's wristwatch to indicate a goal has been scored.
    In line with Fifa's requirements, the whole process takes less than a second to complete.


    Calls for goal-line technology have increased with dubious decisions marring a number of high profile games last season.
    Chelsea's Juan Mata was awarded a goal that had not crossed the line in his side's 5-1 FA Cup semi-final win over Tottenham on 15 April.
    And QPR defender Clint Hill's header was clawed back into play via the crossbar from two feet behind the line by Bolton goalkeeper Adam Bogdan during the London club's 2-1 defeat at the Reebok Stadium on 10 March.
    Andy Carroll believed his header had equalised for Liverpool against Chelsea in the FA Cup final, too.
    Wembley has seen many controversial goal-line incidents over the years. The most famous came during the 1966 World Cup final, when Sir Geoff Hurst's shot was ruled to have crossed the West German goal-line.
    Weeks of talks between Fifa, the Football Association and Hawk-Eye have resulted in an England international being selected to experiment goal-line technology.
    England's match, with an expected sell-out crowd of over 85,000, is seen as an ideal test venue.
    Fifa's independent appointed testing body - Swiss Federal Laboratories for Materials Science and Technology (EMPA) - will conduct further tests after Roy Hodgson's first Wembley game in charge of England, and again the following day.
    The six cameras per goal that Hawk-Eye require are due to be installed at Wembley over the course of the next week.
    In March, football's law-makers - the International Football Association Board (IFAB) - approved two companies - Hawk-Eye and GoalRef - to take part in the second phase of goal-line technology testing.
    How does GoalRef work?

    GoalRef uses a microchip implanted in the ball and the use of low magnetic waves around the goal.
    The system then detects any change in the magnetic field on or behind the goal-line to determine if a goal has been scored.

    The process takes under one second with a message relayed to the referee.


    IFAB are due to make a final decision on the introduction of goal-line technology in early July.
    GoalRef is also currently undergoing tests. Denmark's friendly against Australia in Copenhagen, on the same day as England's match with Belgium, is under consideration for a live test.
    Barring any last-minute problems, the expectation is that one or both systems under review will gain approval.
    If that happens, any league or competition will be free to introduce the systems if they wish.
    Despite the Premier League's long-term enthusiasm, the indications are that there may not be sufficient time to install a system in all 20 top-flight stadiums in time for the start of the 2012-13 season.
    The German, Swiss and Dutch leagues are also thought to have expressed an interest in adopting the technology.
    Fifa's World Club Cup competition in Japan - which will involve newly crowned Champions League winners Chelsea - could also feature one of the approved systems.
