I started working with VR in 2015. I bought the Innovator Edition of the Samsung GearVR for the Samsung Note 4. That year I participated in the Samsung VRJam2015 with my entry Aetheria: Weekend Retreat. This is how I described it for the Jam:
Originally I had started with a tea-drinking meditation focusing on each of the senses, but it was difficult to do while in the headset. So I switched to chocolate. Upon later reflection and discussion with meditation practitioners and instructors, chocolate is a very "charged" item with too many connotations to be easily meditative, so some rework would be required.
It was seriously challenging to make "realistic" environments for the GearVR, especially on the Note 4. I got creative with skyboxes and pre-rendering panoramic views. At that time it wasn't common and proved to be difficult, but I resolved it to create a working demonstration of a Weekend Retreat with 5 meditations and suggested "homework" for users to try at home.
It did get a little write-up on VRBites:
