Rumours and Stuff

[Barry O'Speedwagon]

I feel like if I think hard enough I will know what velocity is.

It's basically speed, but is always measured with reference to a particular direction. So technically if you run across field your velocity relative to the try line is zero. But....most people use the two interchangeably.

Trust Barry to get all sensible .... ffs

He just nose his speed

 

[Twizzle]

I pacifically said the velocity immediately before the ball is passed. A point in time measurement. I was very pacific about that.

nice attempt at deflection and humour, however, it's irrelevant as this does not allow for lateral movement

as you may know, speed involves measurement of time but velocity involves measurement of direction and lateral movement changes direction and velocity is your main argument here

your turn

NRL Unpacked: Deep-dive into NRL's advanced forward pass technology

The NRL is entering the late stages of trials with ball-tracking technology that has the potential to eliminate forward pass errors – among many other potential benefits.

Hey, NRL - here's an idea:

Instead of focusing on forward passes, why don't you focus on your ridiculous inconsistencies when penalising, and disciplining, players?

Knee a player in the back, and break their ribs? No worries.

Knee a player in the back, and break their ribs, while wearing an Eels jersey? Four weeks' suspension!

Strike a defenceless player's head with a swinging arm? Merely a fine!


Ffs


The game has much bigger problems at the moment.

He’s a grub.

Anyone else think that this concept is odds on to go completely pear shaped?

Not sure how this will work. If ball leaves the hands backwards but floats forward what will the technology say?

see above the deep dive from nrl.com It didn't really change my mind but would be interesting to see in practice. My cynical side says that no matter how good the tech is, there's' still going to be rugby league numbskulls lining up to f**k up the interpretation.

^^^^^^

How does it work?​

The Steeden footballs are implanted with a piece of technology that weighs just a few grams. They contain an accelerometer, a gyroscope and a magnetometer that are charged via a cable and recycled once the ball reaches the end of its usability.

"We literally have a device for tracking them in 3D like radar," Husemeyer says.

We track it like we track a missile.
Pete Husemeyer, Sportable

"We know its exact position at every moment in time. Then we add to that the accelerometer and the gyroscope and the magnetometer."

The gyroscope measures the spin of the ball, which Husemeyer says is an important part of the equation, while the accelerometer is the same type of software in smartphones that measures speed and changes of direction.

"Using that real time data, we're able to infer the angle of the passer's hands as the ball leaves the hands," Husemeyer adds.

"If the player is running and their hands are angled sideways, the ball can still float forward with momentum but it's actually a flat pass.

The key thing isn't whether the ball went forward or not; the key thing is to know the angle of the passer's hands.
Pete Husemeyer, Sportable

In the average game, a majority of passes technically travel forward in the sense they are caught in front of the point they were delivered from.

Husemeyer says the technology can separate which ones were passed backwards from the hands and travelled forward with natural momentum compared to which ones were propelled forward out of the hands.

That's why I emphasised the forward component of velocity. Like Barry said, if you're running across field the forward component of your velocity is zero. Keep up.

what traps?? So he can sign with the Dolphins?

Ahhh, just kidding, April Fools and all.....

You didn't take the bait, kudos.... I thought it would generate a flurry of activity!

More fool me.....
