Recording Activity in Virtual Environment

I'm trying to come up with the best solution regarding my project. The idea is that once they enter the game, I have to "record their activity" in the environment. Which requires basically either a video format as an exported version of their in-game activity or basically a script which exports a .doc/.txt file of their activity.

What I mean by "activity" is basically how many times the user picked a certain object by pressing a button when they are in game.

Currently the project is set to Oculus VR system.


What are my options and which is the most easier way to tackle this issue? if so are there any tutorials I could follow regarding this?

 

Any idea?
