Track Device Pose with Rotational Tracking does not extended track the ImageTarget

September 11, 2019 - 3:38am #1

Vuforia SDK Version: 8.3.8 -

Description with steps to reproduce: Hi, Im using Unity 2019.1.14f1 and Vuforia 8.3.8. and build for an iPhone 6, 7. When I enable "Track Device Pose" and select "Rotational Tracking" the scene has the same behaviour as when i disable Track Device Pose completely. I expected that the "Rotational Tracking" would be a sort of lower quality extended tracking like the ones from previous vuforia versions. The reason why I want to use the old way of extended tracking is because on iPhone 6 and iPhone 7 devices the "Track Device Pose" with "Positional Tracker" enabled, causes lagging. It seems that this function needs too much performace of these older devices. Could you give me a hint how I can use the old extended tracking using only inertial sensors instead of the VISLAM way ? greetings, -

Track Device Pose with Rotational Tracking does not extended track the ImageTarget

Hello,

Rotational Tracking only applies to 3DoF device tracking experiences (e.g. AR/VR). Note that this feature has also been marked as deprecated in Engine SDK 8.3:

Unfortunately, there is no way to enabled Extended Tracking using inertial sensors only. If your devices are experiencing significant CPU consumption due to VISLAM tracking, then perhaps you can consider using the legacy Extended Tracking feature (e.g. vision only - no sensor fusion). Please refer to the following article (see Fusion APIs section): https://library.vuforia.com/content/vuforia-library/en/articles/Training/vuforia-fusion-article.html.

And the following APIs:
