In the area of seating, there is a tendency to regard human beings as ideally-proportioned two-dimensional figures. EOOS brings a more complex interpretation of the seated individual to its designs. In partnership with Keilhauer and the Technical University of Vienna, a computer program was engineered to chart all movements of a person sitting on the chair. The research was based on the idea that the chair should follow the movements of its occupant,
rather than forcing the person to conform to the fixed mechanics of the chair. The program, dubbed ASA (Alternative Seating Analysis), was used to analyse products of competitor companies as well as ergonomic prototypes built by EOOS. The findings thereby gained provided the foundation for a research project by the University of Waterloo, Ontario, which scientifically verified the assumptions made by EOOS in a wide range of tests.
