App Description
Turn your phone into SlimeVR tracker for VR full-body tracking
This app turns your Android phone into a tracker for SlimeVR Server or other supported server applications such as K2VR for IMU-based full body tracking. You can also run owoTrack on some Android-based Wear OS smartwatches.
This does not perform camera-based tracking; it does not use the phone's camera. owoTrack requires your device to have a gyroscope - some phones may lack this hardware.
If you have no other trackers and 1 phone, you can use this to get waist tracking only. For leg tracking, you will need at least 5 phones or some combination of official/DIY SlimeVR trackers, phones/watches (through owoTrack), Joycons (through SlimeVR Wrangler) to get 5 trackers in total. Tracking quality may vary depending on type of devices used.
