The robot uprising
But instead of Schwarzenegger and the Terminator it's Reg from On The buses
Weeks after Cruise launched its autonomous, driverless taxi rides to the public in San Francisco, numerous vehicles mysteriously piled up and blocked several lanes of incoming traffic downtown. Apparently a bunch of driverless Cruise vehicles were "stuck" blocking an intersection for "a couple of hours" the other night, …
Why not just put tags in the back of everyone's shirt and track that and the ball - no AI required...
If player's Z axis location is further forward than all but one of the opposition when the ball air pressure spikes (because it's being kicked) then flag potential offside - with an indicator on screen as to the player in question and the ball at moment of pressure spike.
@John Robson "ball air pressure spikes (because it's being kicked) then flag potential offside"
Needs to do more than just react to ball air pressure spikes otherwise the vast majority flagged as potential offside will not be offside.
The ball is kicked, headed, bounces, etc all the time, the majority of air pressure spikes are not due to a player releasing possession.
Also the system would have to identify which player and team was releasing possession to identify if that teams players were offside.
Back to the question Does it really need to be AI? No it does not.
Or does it need to be done at all? I'm not really familiar with all the details of commercial lycra-based entertainment but I seem to recall they just toss a coin to decide who makes the first move. Couldn't they apply the same technology everywhere a decision is required?

Oh I don't hate it - it's not worth the effort.
Of course I call it soccer whenever I have to refer to it, and generally treat it with the disdain it* deserves... but hate is going too far.
* Commercial soccer that is. I have nothing against school/community based sports**.
** No using a golf bat on a golf court doesn't count as sport.

I thought all the players did wear some tech now anyway to track their heart rate, distance run, etc. A sensor sounds like a simple extension. Although humans are not a point location; perhaps they have tried both and decided this is better, perhaps it's a human factor that they couldn't get people to agree.
The whole offside technology thing is flawed from the very beginning, because they are trying to use technology to answer the wrong question. The point of the offside rule is to prevent strikers from loitering upfield behind the opposition defensive line. It's not to call offside against a striker whose toe just happens to be 2mm beyond the toe of the last defender. Adding ever more *precision* will not improve *accuracy*.
Having a pressure monitor in the ball to note when it was kicked is simply an extension of this, a technological replacement from simply eyeballing when the ball was last hit and freeze-framing there. The problem is that football footage is filmed at 50fps (a frame every 0.02s), players can run at 35-40 km/h + (over 10 m/s for 1 player and over 20m/s relative speed for 2 players running in opposite directions). That means there could be up to 40cm difference between frames. Film at 200fps still gives 10cm difference between frames.
FIFA and everyone else involved simply needs to accept that there is a margin of error that they won't improve upon, and instead of investing in technology that pretends it can tell if someone is 2cm offside, maybe invest it in fan education campaigns
It *is* illegal, so there's the fine, and they must stop whatever they were doing amd delete it.
Since they continue asserting that their interpretation of the GDPR is the only one that matters, it might get interesting when they become a repeat offender.
Those driverless Cruise cars sound like the church carpark when I was little, with all the drivers trying to our-nice each other when everyone left at the same time.
"After you." - "No no no. After you." - "But I insist. After you" etc etc etc.
Deadlock conditions are bad enough in software, without having them cross into the physical realm as well.
A player can be offside by an inch or less, so how do they ensure the sensor is exactly in the middle of the ball and how do they know where the players foot is in relation to the defending side?
I bet it’ll cause more problems than it solves.
[ ] you understand offside
[x] your prediction of that AI-thingy causing more problem than it solves is likely correct (adn I share that sentiment)
The position of the ball has not too much to do with it. It is the position of the players you need to care about. And yes, that can be a matter of a few 2.5cm. The position of the ball matters when it comes to scoring not-goals (*cough* Wembley).
"Apparently a bunch of driverless Cruise vehicles were "stuck" blocking an intersection for "a couple of hours" the other night"
The best test site for these would be the Hemel Hempstead UK Magic Roundabout: - five roads (three of them trunk) into five unidirectional mini roundabouts surrounding a bidirectional main roundabout. If 'driverless' vehicles could negotiate this in the rush hour among conventional traffic (including buses) the problem would have been solved. If not, more work still needed.
