eyetrack | Experimental code for gaze tracking | Azure library

I want to implement a feature on HoloLens2 app, which allows user to draw/paint on specific surface in every part which was touched by the user.

So we have a flat plane and when I move my hand over this plane, spots below my hand should be coloured. How can I implement such feature keeping in mind, that HoloLens has limited processing power and calling Texture.Apply() every frame is unacceptable?

I tried to adopt a script from Eye tracking Heat map demo scene to use hand touch instead, but didn't success.

I've changed

I'm creating a small demo where objects shall move based on the eyetracker data from a FOVE VR headset.

When I try to move my two objects around ("Gaze Responder - Target" and "Gaze Responder - Fixation"): They don't move, and the colliders stop working.

I have the following hierarchy in Unity3d (2017.4.40f1)

The following Code is attached to GazeContingenVisualField

I have some eyetracking data from participants that watched some short (12-14s) videos. Now to get an overview on the data I would like to plot the fixation over the video.

I found matplotlibs FuncAnimation that can create animations and could create an animation showing the fixations over the presentation of the video.

I am working bulid a eye gaze visualization tool just like this by PyQt5, and I also checked this post. here is the code by modifing the above links. turn out it's worked, but the video always get stuck sometime (the audio is normal, the the frames stuck, both video content and ellipse,just like this video),anyone can help?

I have two dataframes, one (called "trialTS") which contains a series of "trials" (1,2,3, etc) and a start and an end timestamp:

I am trying to find the gaze co-ordinates of a user wearing a HTC Vive with integrated Tobii Eyetracker. The user is viewing a 360-degree video playing inside a Unity Skybox. I am using the Tobii Pro SDK.

I have used the VREyeTracker Prefab of Tobii and am getting parameters and values in the XML file (more details below in results). How is Unity Data different from Raw Data? Since I am not able to find any document with relevant description, I am not sure if the results obtained in the XML contain the information I am looking for.

Unity Data:

• A separate process calls a function whenever data is available and provides that data as the input to the called function

• In the function I process the data, and want to make results of it globally available (i.e., a globally available variable changes its value dynamically)

• What is a clean method to achieve this across modules, when within a module, this job would be performed well through a global variable?

I use an eyetracking device (Tobii 4C) that can provide gaze data of a human via a Python API

The typical flow would be to:

1. initialize an eyetracker object, pointing to the eyetracking device
2. "subscribe" the eyetracker object to the actual data: eyetracker.subscribe_to(DATA, callback)

The callback is a function handle that gets called everytime the eyetracking device has new data available. Typically it would be used to save data, e.g.:

I want to make an alert after the user's eyelid is closed for more than 3 seconds but I have a problem with my code. How can I make the boolean right_eye and boolean left_eye trigger the alert after 3 seconds it closed? Here is some code that I wrote.

Currently I am doing research to chatbot interfaces and make use of eyetracking to test my prototypes.

My eyetracking device creates a csv file with a x and a y coordinate every 16 mili seconds.

I want to plot this information with:

• The X-axis on the top
• The Y-axis on the right (starting with zero at the top)

Currently I have the following code:
