VuMark recognition

August 17, 2016 - 7:02am #1

I am familiar with using frame markers and I have some questions about changing over to VuMarks. I am developing an app that will be used by children, so I want to understand the privacy implications of switching.

It is my understanding that frame marker recognition takes place completely on the device. Additionally, with frame markers it appears that the only time an app communicates with Vuforia servers is when it verifies the license and transmits device stats at start-up. How is this process different for VuMarks? How often does the application communicate with Vuforia servers when using VuMarks? Are any images from the camera transmitted to Vuforia?

Hello,

The fundamental difference between FrameMarkers and VuMarks is the requirement for a device database. FrameMarkers are built into the SDK so no additional recognition information is required. VuMarks are custom, similar to ImageTargets, so a device database needs to be created and integrated with the app that will use them. Thus, VuMarks can be recognized while the device is not connected to the Internet.

Thus, the VuMarks feature sends no additional data to Vuforia's backend services compared to FrameMarkers. This include camera images.

Hope this answers your questions.

Thanks.
