Can GazeR analyze eye movement data in virtual reality environments?

[Liujiaxu-Xx]

We built a 3D scene in Unity and then used the HTC VIVE pro eye, a virtual reality headset device, to obtain eye movement data as follows. The data includes pupil size, gaze direction, and gaze starting position for both eyes, but the coordinates include X-axis, Y-axis, and Z-axis. Can GazeR analyze such data? And we exported the CSV file directly.

To use gazer you must have at a min participant id, trial id, pupil size, blink (you can use whatever algo you would like). you can use make_gazer to get your data in acceptable format to use in gazeR

make_gazer <- function(data, subject="subject", trial="subject", time="time", x="x", y="y", pupil=NULL)

``` . 

It looks like you used Tobii inside the VR? I see the openness column (I believe you could use that as proxy for blinks)

I want to add that this would only work for analyzing pupil data. The gaze function would probably not work here.

This is no way to calculate the gaze time, sweep time?     ------------------ Original ------------------ From: @.>; Date:  Thu, Apr 6, 2023 08:55 AM To: @.>; Cc: @.>; @.>; Subject:  Re: [dmirman/gazer] Can GazeR analyze eye movement data in virtual reality environments? (Issue #28)

The gaze features are limited to simple ROI type designs (proportion fixation on certain coordinates). You could probably use the saccades package if you want fixation duration.

I also don't see any message columns. I don't think that is a feature with Tobii SDK for VR?

We did not use the Tobii SDK, we used the SRanipal SDK that comes with HTC. then we exported the data by writing C# code.     ------------------ Original ------------------ From: @.>; Date:  Thu, Apr 6, 2023 09:19 AM To: @.>; Cc: @.>; @.>; Subject:  Re: [dmirman/gazer] Can GazeR analyze eye movement data in virtual reality environments?

The eye openness column lead me to believe it was Tobii.

Does SRanipal allow output for messages (when things appear on screen or when buttons are pressed)?

SRanipal can only capture information from the eyes, other interactions (button presses, pop-ups) may require other SDKs or writing code.     ------------------ Original ------------------ From: @.>; Date:  Thu, Apr 6, 2023 09:28 AM To: @.>; Cc: @.>; @.>; Subject:  Re: [dmirman/gazer] Can GazeR analyze eye movement data in virtual reality environments?

我们没有使用Tobii SDK，我们使用HTC自带的SRanipal SDK。然后通过我们编写的C#代码导出数据。 ------------------原创 ------ - ------------- 来自：@。 >;日期：2023年4月6日星期四上午09:19 早餐：@ *.>;抄送：@.>; @.>;主题： 回复：[dmirman/gazer] GazeR 可以分析虚拟现实环境中的眼动数据吗？（问题#28）我也没有看到任何消息栏。我不认为这是 Tobii SDK for VR 的功能吗？ — 直接回复此电子邮件、在 GitHub 上查看或取消订阅。您收到此消息是因为您创作了该主题。消息 ID：@ .>
