Problem, perhaps, with lights... and, make a "video interface"

Hello there!
Sorry to bother you, I have two questions!
1) with my museum app I noticed I have the AR content (what I augment on reality) "flickering"; in other words when I'm targetting the marker I have to stay at a fixed distance (and with very firm hands!) or the content is intermittent. Every 1 second it goes away and returns... it's very disturbing and you waste some time to adjust to the right position to visualize the content (it's very vexing with content with some text, wich you cannot read). I think is a problem of lights, but with a large number of people in visit (they project some shadows, even for a millisecond, but I think they are sufficient to create the flickering effect) and not real possibility to illuminate like a nova the museum... ther's any trick (or software trick, in the code at your end) to eliminate this problem?

2) if I want to insert some commands on my AR video (foward, stop, pause etc.), and I cannot make this via marker... can I insert a video interface wich activates when the video start?

Greetings, Damiano

Hello,

1 - check your marker complexity, maybe it doesn't have enough contrasts and features to be detected faster and a stable way.
   - Tips try to add a QRcode somewhere on the marker it will help to detect faster.
   - how many markers your app can detect ? maybe you have too much for the device you use and it take too much time ?

2 - sure you can add buttons and show / hide them when needed

Re: Problem, perhaps, with lights... and, make a "video interface"

Hello!

1- so I have to insert in the marker a qr code? how much big respect  my marker? (for the sake of discussion, my marker are the default marker generated by OS3D)...
- I have 20 markers, but separated in different "app", linked togheter by instances

Thank you very much!

ho ok you use the aruco fiducial markers, I didn't known.
Yes maybe you can try with natural features.

Also a big tips that is proven, if markers are hard to detect "clean the camera lens!" dirty camera lens make the picture blurry and make the aruco markers hard to detect.

For "natural" you mean "normal (not aruco, not qr code, not abstract markers) but contrasted figures"?
Do you think if I use only qr code it can be the better option?

QR code images are well detected using natural features (trained picture)
