Connecting Fitbit With AR/VR Headset

[ARTLLC]

Hello Fitbit Developers,

 Is it possible to create an application for your Fitbit device, using the gyroscope and accelerometer sensors, and connecting the watch to an augmented reality or Virtual reality headset, in order to track motion? We are using the Unity SDK.

 Thanks,

 Justin

It would be possible but difficult and probably not worth the effort. Here's a repo that gets accel data in real time, and streams it to a browser. See MP4 vid samples. Instead of a browser, you would use your Unity app.

I don't think it would be very accurate, since determining position would require double-integrating the accel data after adjusting for orientation (which isn't available on many watch types). Inaccuracies would accumulate rapidly.

Hi @ARTLLC - for info, only the original Versa or original Sense have a Gyroscope.

Thanks for that feedback. Do FitBit applications depend on Google Play Services?

No. Google Play is only for Android and Wear OS.

@ARTLLC - to elaborate, any apps created to run on the smart watch are created using the Fitbit SDK CLI interface which will be needed to get access to the Gyroscope and Accelerometer information in real time. 

It can come in 2 parts, the part that runs on the watch and the part that runs on the phone which can display information in the Fitbit app and/or communicate with the outside world via internet but not normally the phone storage or OS itself unless you setup a web server on it.

Anything written to run on the phone can be deployed through the Playstore or Applestore (or locally).
