Lucy Suchmanm, did wonderful job in the Xerox PARC, whcih research to see that enhanced real world context play a important role in the tech design, and it will change human’s perspective towards technologies from roots. Her most influential contribution is studied how people use of Xerox copiers and shows the difference in design thinking and real user experience.

Traditionally, tech design is base on a hypothesis that if user simply follow the order that machine can work effectively, However, Suchmanm’s ethnographic approach says people will not strictly follow the logic or linear standard to control a machine, instead, they will do the opposite, they create, they freestyle, which the real life situation is much more complex and disorder then the expectation.

This work from her makes the human interaction and tech design wellspread and emphasis the human center design as well as the context aware system. Designers now focus more on how technology fits into users’ everyday practices and how system operate to cooperate into the distinctive real life environments.
