Hello, what you want is so easy with zenphoto. No need for a new plugin.
I do it like mentioned by acrylian :
on your mobile, landscape mode, use the square for full screen and the compass for enabling smartphone movment.

In zenphoto, in your album, for each 360° picture, simply use a txt file containing this kind of code :
iframe width="800" height="530" allowfullscreen style="border-style:none;" src="path-to/pannellum.htm#panorama=Path-to/your-picture.jpg&autoLoad=true&hfov=100&maxHfov=100&minHfov=30&vaov=128&yaw=190&minPitch=-90&maxPitch=35&pitch=-40&autoRotate=-5">/iframe
Note < and > are missing in my code, because otherwise, I cannot show you that code
A better way is to use json files : more options with pannellum (free).

You add a jpg picture named like your txt file for the thumbnail.
More examples here ... thank you Zenphoto ...

Of course, all mobile do not have gyroscope function - maybe you call it movement detection. In that case, you have to use your finger to move around the picture.
