eye tracking Vive focus 3 eye tracker connected to a pc

[Marius]

Hi, regarding the Vive focus 3 eye tracker i know if you connect it directly to a pc it gets detected as a vive camera so i wonder if you can see both of the camera inputs on the pc with a recording software?

And if you connect it to a pc will the ir emitters on the eye tracker power on by them self?

Can focus 3 eye tracker and facial expression tracker be used in research? If so, which SW should we use? Can you direct me to a page, where more info can be found?

Hi,

what SDK do you use for the Eye Tracker add-on for Focus 3?

How do you connect the eye tracker to the headset, while connecting the headset to PC? I'm thinking to use a non-native cable to connect eye tracker to the bottom port of the headset, and use the native pc-vr cable to connect the side port of the headset to the pc. Any advice?

Any help would be greatly appreciated.

Hi @houb3,

Yes, you can connect eye tracker to the bottom port of the headset and use another cable to connect to PC using the side port.

For SDK, please use the latest Wave SDK (5.2.0-r.8).

Thanks @chengnay.

Noob question: what's the difference between SRanipal and Wave SDK? (I'm using Unity)

Is there any links on how to get the 120Hz eye tracking data using Wave SDK? I guess the tutorial code and the API reference reads the eye data in the Update loop at every Unity frame refresh, rather than using a separate Callback thread, like here using SRanipal?

Thanks again.

Hi @houb3,

SRanipal is for PCVR.

For Focus 3, you will need to use Wave SDK.

Of cause, you still can use SRanipal's sample scene(including scripts) for development.

Just you will need to spend some time to update the script to run on AIO device.
