Elements of successful design

Outlines some general principles and methods for developing successful instrumentation. Successful design involves interdependent elements (presentation, ease of use, and intuitiveness) shaped by the designer and the user. These elements evolve through rapid prototyping into a mature, cohesive design. Rapid prototyping requires the cooperation of the designer and user to fuel the successful evolution of the instrument design. The Neurological Stimulation System (NSS) developed by the Johns Hopkins University provides a case study for combining the three elements of design into a successful instrument. In particular, it was found that packaging the custom enclosure in an attractive case dramatically increased acceptance of the design. >
