I designed a 360 degree environment for subway carriages. I first drew it as sketches, and then using an app called "Image Sphere Viewer" to render the sketch into a VR prototype.

I also created two micro interactions for the VR experience in this environment. One is to show the training schedule by tapping the wristwatch which will appear when the user is gazing on his/her wrist. The other interaction is get the weather information outside of the subway by virtually wiping the subway window.
I was using two metaphors derived from our daily experience to create the design ideas for both interactions: looking at the watch for the time information, and looking outside of window to check the weather.
