Mike Pell pointed me to the web site of George Robertson, of Microsoft Research.

George’s Recent Publications and Talks will likely be of interest to brad lauster (dot com) readers. Specifically (the reason I posted this in Interaction Design), “Leveraging Human Capabilities” [power point].

Also interesting, with perhaps more of an Information Architecture bent is, “From Hierarchies to Polyarchies: Visualizing Multiple Relationships” [power point].
