What is considered a "Recognition Event"?

December 2, 2013 - 6:51pm #1

Hello,

I'm looking for some verification of what I've read to be a "Recognition Event" from the Vuforia Cloud Recognition Service Agreement from this link, https://developer.vuforia.com/legal/cloud-service-agreement.pdf .  The agreement says, "'Recognition Event' means the response from the Service corresponding to a Query." I'm still a little unsure about what exactly is counted as a response from the Service.

I've looked at the sample cloud recognition sample, and I can see that the cloud recognition sends a search query to the Vuforia cloud service. A query appears to be sent based on the Vuforia code detecting trackable points in the scene. A callback checks to see if the search was a match or not. While monitoring the search queries, I could see that multiple search querys are sent that recieve no positive match to a marker.  I kept the camera pointed at the same scene and noticed that another query was not sent. 

From reading the service agreement a  "'Recognition Event' means the response from the Service corresponding to a Query," Does that mean that only a response from the Service that contains a positive match is counted  as a recognition event, or are negative matches are also counted?

Only the positive matches are counted as Recognition Events. Cloud Recognition search queries that don't return a matching search result from your Cloud Database are not counted against your quota. 

See: https://developer.vuforia.com/cloud-recognition-service/faqhttps://developer.vuforia.com/cloud-recognition-service

This is a good question to ask, because the distinction is significant. We are only counting successful searches so that you can design your apps knowing that your quota will be applied effectively. 

Also take a look at our Unity Cloud Reco Tutorial - https://developer.vuforia.com/resources/tutorials/creating-cloud-recognition-apps-unity , this demonstrates a more basic Cloud Reco implementation that clarifies the stages of the Cloud Recognition search behaviour.
