What's a "Reco" event?

February 26, 2015 - 12:21pm #1

Can someone please tell me precisely what a "reco" event is?  I'm trying to get a sense of what the new pricing schemes mean, but I can't find a precise definition in the documentation.

The best I can find says that when a target is recognized.  But, is that EACH time, or just each time the app is run?  It can't be each time, since that implies that if a user looks at something, looks away and looks back, they trigger 2 reco events.  Since we work with kids and educational games, where the device is often laid down (all tracking lost), this could imply dozens of reco events per kid per use of the app.  If that's true, any app (even an unsuccessful one) could blow through the kind of limits they have in the plans really fast.

So, I assume I'm interpretting in wrong!

I missed that FAQ and the 5 second comment.

That's insane.

dylanmalone: Indeed, but on device events still seem to be unlimited for the free license, but not the paid ones. That fact alone suggests that someone in sales didn't think this through very well. And yes, Metaio is certainly taking advantage of this to draw business away from Qualcomm. The Vuforia twitter account seems to suggest some kind of imminent response on these forums; I wait to hear what they're going to say.

nknouf - definitely they count every recognition event, other than the 5 second window to prevent minor tracking lost events from costing money.  Amazingly, though it has no hard cost to Qualcomm and no impact on their backend services, on device recognition events are no longer free, nor even available at a flat pricing system.  That is the reason why Vuforia teeters on the edge of extinction as far as I can discern.  Must be a good day to be one of the other AR systems out there.  :/

Unfortunately, your interpretation is correct, according to the FAQ: https://developer.vuforia.com/library/articles/FAQ/Usage. If the re-recognition occurs within 5 seconds, then no, a new event is not triggered, but outside of that 5s window, as far as I understand it, yes, you have a new reco event. Which is crazy.

What I'm still wondering, as well as many other people, and what I've been unable to get a straight answer to, is if the limitations on reco events for the paid plains include recos for both offline and online (cloud-based) recos. Because the free plan only seems to count cloud-based recos, but the paid plans seem to count both. Which is even crazier.
