Thanks, have you also checked if this is working on Vuforia 2.8 ?
While testing this, I noticed that the Continuous autofocus can react a little it quicker or slower depending on the device;
- on some devices it is very quick in realizing the view change and adapting the focus,
- on other devices it takes a little bit more time, and sometime it just does not get the right focus that you would expect: for example if the camera is too close to the target, it might get stuck in some out-of-focus state (=> blurry image) until you move the device a bit (or until you press the button again)
- the performance I observed also vary with different lighting conditions (certain devices react quicker in bright environments and have more difficulties to adjust the focus in low lighting)
- however, I compared the results of Vuforia 2.8 and Vuforia 3.0, and I did not really observe any difference; to me this looks like something that depends on the actual autofocus capabilities of the device.
Do you have evidence that in Vuforia 2.8 things were running better than in 3.0 ?
