Hi @user-8f94e8. May I ask which eye tracking system you're using onboard the HL2?

Hi @user-e1d04f ! You can request a quote for the VR add-ons at [email removed] note that we do not include the HTC Vive which has to be purchased separately.

Hi guys. I need your help on GazeDemo. I play it in Unity 2020.3. I have Pupil Capture version 1.15.65 installed. The problem is that after calibration, I see this message on unity game window: 'Calibration routine is done. Waiting for results....'. Then Pupil Capture crashes and no results. What should I do??

Hi @user-177371 , that version of Pupil Capture is quite old and in principle, no longer supported. The current official version on Linux (which I assume you have, since you are on 1.15.65) is 3.5.8. I highly recommend upgrading.

If you are using hmd-eyes, then I also recommend checking that you are on version 1.4.

hi,I would like to ask if HMD-Eyes must be used with a helmet, or can it be used with only pupil-core?

user-d407c1 26 July, 2024, 09:48:13

Hi @user-b69caf ! HMD-eyes is designed to be used with the Core VR-Addons in a Head Mounted Display context (HMD). One of it's routines is the calibration which presents stimuli on the VR display and associates the eye images to them, in order to provide gaze on that Unity space coordinates.

If your plan is to use Pupil Core with Unity, you could re-use many components from the HMD-eyes library (like the ZMQ lib) to communicate with Unity, etc. But there are several factors that you would need to account, like how you translate the coordinates of gaze from the scene camera of Pupil Core to Unity.

This previous message might point you on one direction to do that. https://discord.com/channels/285728493612957698/446977689690177536/1248580630430875661

Hi @user-b69caf , do you mean that you want to use it with a VR headset that has a different eye tracker?

user-b69caf 26 July, 2024, 09:35:11

@user-f43a29 What I want to ask is, my computer is not connected to any other headset, only Pupil Core is connected, and then running GazeDemo in HMD Eyes, can I obtain accurate eye tracking data in Unity editor running mode

user-b69caf 26 July, 2024, 09:36:56

Received a render script that requires input of pupil size and position information

@user-d407c1 thanks,I'll go research it
