Post-processing and missing labels

1:21:41what I think is happening is that there is post-processing algorithms that are taking the raw data because what we're seeing right now is just a 1D trace. First of all, it it's infuriating to me that there's no axis labels. >> Okay? My PhD adviser would [laughter] would have my neck if I presented him any data that looked like that. And for good reason. Okay, you got to have labels on your axis. Tell me like a seconds uh and and what the y-axis even means. Is it a meters/s? Am I looking at acceleration? Am I looking at angular acceleration? What am I even looking at? Is it jerk? Is it the derivative of

1:22:21acceleration? So on and so forth, right? So anyways, there's got to be there's like a sensitivity threshold, right, for when things get triggered, >> right? >> And I think there's got to be some post-processing of the data that is happening, >> right? >> Which which is true of of a lot of sensor platforms where you have the level of volume of data. There's just so much noise. You have to what are you what are you looking for? >> Yeah. And in any case, the IMU is measuring three units of acceleration. It's an X, Y, and Z in acceleration. If something is spinning, you're going to get a acceleration in X, Y, and Z, and all of those are going to cycle through which is going to cause the spinning. So, the fact that I'm seeing this like

1:23:02flatlining means that there is some post-processing going on >> fundamentally, >> right? Fundamentally, we're not we're not even seeing the like cuz it would be anyway, we would see a three-dimensional thing. >> Yeah, I would see three traces at least, but I'm seeing only one now. Perhaps they're signaling out one, but in any case, I'm not seeing the whole thing. Okay, we can all agree that this is not raw data that I'm seeing >> 100%. >> Okay, with no labels. >> Yeah, with with with no labels. Okay, now the second thing is now if the ball is spinning and it's it's subject to this constant acceleration, right? There's got to be an algorithm that's looking for a discrete touch like the one that the goalie had, like the one when he when he fell. >> Um >> or the one where it hit the hair of the

1:23:43one player on the >> and actually that's the next one. If you if you go to if you go to the next one, we've got Croatia versus Portugal. There's a little bump of it hitting the the guy his hair and then all of a sudden um Croatia's goal is disallowed. Right
