Features

Frequently asked questions about Lens features and their behavior on Spectacles, including tracking, audio, and connected lenses.

Marker Tracking

Marker Tracking is supported on Spectacles. Ensure that you set the correct size (in centimeters) for the real image marker in the Image Tracker Asset within Lens Studio.

Audio Component

Developers can use as many Audio Components in the Lens. However, the limitation lies in the number of audio assets that can play concurrently. If a Lens is scripted to play more than 16 Audio assets simultaneously, it may result in audio not playing on Spectacles.

Connected Lens

When a user joins a Connected Lens session, the following sequence occurs:

1. Session has been created
2. Mapping has been started
3. Mapping has been done
4. User has connected to the session
5. Storage Properties have been created

For more detailed flow chart, Please see Lifecycle for SyncKit.

Face Tracking

Yes, Face Tracking is supported on Spectacles with some limitations.

1. Use Head Binding component to attach 3D objects to the head.
2. Ensure that Attachment Point Type is ONLY set to Candide Center, Right Eyeball, or Left Eyeball.
