Focus 3 eye tracking timestamp with Wave Unity SDK

[houb3]

Hi, 

Im using Focus 3's add-on eye tracker. I need the device timestamp. 

When I was using the Vive Eye Pro with SRanipal, there is a function to get deviceTimestamp(ms). Is there anything similar with the Wave SDK? I need the eye tracker's device timestamp.

Thanks a lot.

I had to use the Wave Native Unity SDK, something like this got me the timestamp in nanosecconds. Wondering if this is available in Essence?

using Wave.Native;

//...//

 

WVR_EyeTracking_t eyeData = new WVR_EyeTracking_t();

WVR_CoordinateSystem space;

Interop.WVR_GetEyeTracking(ref eyeData, space = WVR_CoordinateSystem.WVR_CoordinateSystem_Local);

 

Long deviceTimestamp_ns = eyeData.timestamp;

Hello! So I have been trying for a while to obtain data with the eye tracker accessory (Focus 3) but I can't seem to get it to work inside Unity. Would it be possible to tell me how you were able to get it to work. Also, does it work through DirectPreview?

Thanks!
