Aaron Marcus on interaction design

Aaron Marcus interviewed by Sharon Poggenpohl:

There are design documents which designers make, that convey wisdom and are part of transactions with colleagues from other disciplines, and users. We as designers must talk increasingly with and communicate with other professionals from other disciplines."

In this interview Aaron Marcus refers to his work on "LoCoS" a universal graphical visible language as a replacement for spoken language. It reminds me a lot about a work by Timothy Ingen-Houz: Elephant's memory (from 1994-1996).
