    Default Hawkeye

    Interesting to see the NRL are looking at technology for offside and forward pass decisions.

    Thoughts?

    Would be difficult for forward passes as a pass that ultimately travels forward is often completely fine in rugby league

    How would they decide on it's initial path out of the hands?

    I have no idea, it's not like tennis or cricket where Hawkeye tracks the direction of the ball.

    It does read like the forward pass thing is further away though

    Very true, it does read like that. I’m 100% they could make it work for offsides but you’d have to question how much more accurate they need to be? It’s not a difficult decision although saying this I have noticed VR when the ref has had zero concept of perspective

    I'm not convinced we need it. If it slows down the game, brings in more doubt it's just adding to arguments

    It could be done and reasonably simply. First of all the velocity, acceleration etc of players is already known from the device they wear inside their shirts. You could put microchips inside the ball with receivers in the posts, crossbar and even on every 10 metre line. It would then be a case of developing the algorithm and software to make the decision over 99% corect.
    Technology is still developing at an almost exponential rate.
    Video doctor appointments locally will be available very soon and your mobile devices will relay such things as blood pressure, temperature, heart rate etc etc to the doctor. Picture definition will increase, the possibilities are infinite.
    just to illustrate, back in the mid 1970's I'd just done my last exam for the year in analogue and digital techniques, and I went out for a few beers with some friends. I told them then that within 20 years people would have computers at home. They looked at me incredulously and basically told me I was ••••••ed (I was) and it was stupid, wouldn't happen.
    Lokl where we are now with technology and we've only just begun.

    Whilst I agree that it might be feasible to do my concern would be the cost . Isn’t cost the reason why we don’t have video refs at every game ? For me we need to have video refs at all super league games because in my opinion televised games are refereed slightly differently . Would the game need to be televised to use the Hawkeye system ? Genuine question btw .

    Hardly Nostradamus there Rogues! - home computers were a mass market item by 1980 and loads of people had them in the 70s already

    I had a TRS 80 in the early 1980's, cost a fortune lol.

    Not sure if you would need all that, just use the GPS in the ball relative to the GPS on the back of the shirt, bring the datum together and work out the angle from the ball leaving the hand after 0.5 secs, but I'm not sure if we have GPS signals that are so accurate to within centimetres. The long forward direction ball brings in a lot errors in momentum + wind speed if we use GPS grid lines on the pitch.

    I don't think GPS is accurate enough for these purposes. Hawkeye relies on visual and/or radar tracking I think). I would have thought that some kind of RF tagging along with scanners might be the way forward but I don't know the range. Each player could have a tag and so could the ball and that would be easy. Tagging the ball itself would require more than one tag so the centre of the call could be calculated to allow for spin etc.

    My Dad to this day reckons Sky got rid of the high camera because it was showing refs up on the offside and forward pass. Good idea for me though, and would probably suit us more than most.

    We'd have had about 50 penalties on Saturday.

    Can't see how SL would be able to afford it in reality.

    Unless you had it at ALL games it's another system changing the rules for 'Televised' games.
