Elaborate on your use of perception. What type of perception?

Thank-you for replying.
May you elaborate on what is being evoked from the art piece?
I decided to use the term 'within' initially as I was referring to James Turrel, Olafur Eliasson and Yayoi Kusama's work. Where the being is able to step into the artists 'world' (term used lightly to describe the artist pieces as all the artists listed here create large scale pieces) instead of viewing a piece on a wall, from a subjective point of view and how that person experiences the setting. I should go in depth before hand, I apologise.

Would the term be better if it were an 'Ontological Experience'?

How one exists in the moment and how that environment effects your experience.

Very true.
