c# - 如何跟踪和保存 Hololens 1 的头部注视光标位置文件

Question

我正在使用Microsoft Hololens 1开发者版进行研究augmented reality。我想通过应用程序跟踪头部gaze cursor或head gaze position信息。

请指导我的研究有多少种可能的方法来跟踪head gaze或head-gaze cursor原始数据信息。

是否有可能开发应用程序来记录带有时间戳的坐标的头部注视信息？

Answer 1

Please guide how many possible ways to track head gaze or head-gaze cursor raw data information for my research.

What kind of data do you mean by “raw data”?If you mean the raw data from the sensor at the hardware level, the answer is no.

But if your expectation is to get the direction and origin of Gaze and the position of Head-Gaze Cursor. You can get that from GazeProvider at MRTK:

void LogGazeDirectionOrigin()
{
    Debug.Log("Position at which the gaze hit an object: "
        + CoreServices.InputSystem.GazeProvider.HitInfo.point);
    Debug.Log("Gaze is looking in direction: "
        + CoreServices.InputSystem.GazeProvider.GazeDirection);
Debug.Log("Gaze origin is: "
        + CoreServices.InputSystem.GazeProvider.GazeOrigin);
}

The GazeProvider as an Input Source so users can interact with objects through the use of a pointer. The above code shows how to obtain hit information and call the field point in it to obtain the cursor position. In addition, MRTK does not provide a method that returns the position of the cursor with a timestamp. If you can tolerate a slight delay there's nothing preventing you from doing it in your own code.

Answer 2

Cursor.transform.position给你光标的位置。

Camera.main.transform.position给你相机的位置。

Camera.main.transform.forward给你注视的方向。

我建议您制作自己的凝视光标，以便您完全了解它的工作原理以及如何从中获取信息。
