allows users to view 360º content without a VR headset

Allows users to view 360º content without a VR headset.
I have read the article and used the script from the below link.
https://developers.google.com/vr/develop/unity/guides/magic-window?authuser=1

this is working perfectly fine. check this code:
transform.localRotation =
// Allow user to drag left/right to adjust direction they're facing.
Quaternion.Euler (0f, -dragYawDegrees, 0f) *

// Neutral position is phone held upright, not flat on a table.
Quaternion.Euler (90f, 0f, 0f) *

// Sensor reading, assuming default Input.compensateSensors == true.
Input.gyro.attitude *

// So image is not upside down.
Quaternion.Euler (0f, 0f, 180f);

which helps in dragging left/right. But I also want to swipe upward/downward. Does anyone have idea how can I do this using the script available in the above link?


What does?

i'd guess need to add
dragPitchDegrees += touch.deltaPosition.y * DRAG_RATE;
and then use it in the localRotation = ...
