document: Designing human-centered distributed information systems Many computer systems are designed according to engineering and technology principles and are typically difficult to learn and use . The fields of human-computer interaction , interface design , and human factors have made significant contributions to ease of use and are primarily concerned with the interfaces between systems and users , not with the structures that are often more fundamental for designing truly human-centered systems . The emerging paradigm of human-centered computing -LRB- HCC -RRB- - which has taken many forms-offers a new look at system design . HCC requires more than merely designing an artificial agent to supplement a human agent . The dynamic interactions in a distributed system composed of human and artificial agents-and the context in which the system is situated-are indispensable factors . While we have successfully applied our methodology in designing a prototype of a human-centered intelligent flight-surgeon console at NASA Johnson Space Center , this article presents a methodology for designing human-centered computing systems using electronic medical records -LRB- EMR -RRB- systems
