Quantum Bell-Type Inequalities I'm curious if someone could recommend some supplementary material for gaining a deeper understanding of the paper : "Some Results and Problems on Quantum Bell-Type Inequalities - Tsirelson". 

Specifically something that may elaborate a tad more on the geometric interpretation of Bell-Type inequalities. Perhaps a primer paper or relevant textbook that goes into more detail on these matters. I'd appreciate any/all feedback. Thanks again.
This paper by Barrett et al. gives a fairly intuitive description of non-signalling correlations (what Tsirelson calls non-interacting systems). Sections II.A. and II.B.1. are the most useful and easy to read, the rest is more heavy stuff.
