Virtual and Augmented Reality are topic of many cyberpunk or similar books, yet I cannot recollect of those authors who approach to describe a VR/AR immersed workplaces in a more or less "hard sci-fi" style i.e. going to more detail and following laws of physics etc. Assuming that there are still be many, let's reduce this workplace types to work of a software engineer.
To give an idea - but not a possible answer - let's take Viktor Pelevin's idea of a virtual cube-like tool allowing to explore facets of a phrase in "S.N.U.F.F" (2011) (my own translation):
Grym uploaded the germ of his perplexity and sadness in the creative unit, touched axes "heartier", "sincerier" and then the sub-axis "salinger", which popped in the terminal sectors of the intimate afterburner.
Another good workplace example which is quite close but neither correct, is the protagonist in the movie "Zero Theorem" (2013) who has to solve that theorem using a 3D gaming interface.
Correct answer is the earliest example of a VR/AR workplace which appears more "hard sci-fi" than "fantasy", describing activities related to software engineering.
