Controlling the Computer System the User Interface

  • Ellen M. Johnson


In the days before personal computers, very little commercial software was available for neuroanatomical applications. Researchers who used computers either wrote the necessary software themselves or hired professional programmers or students to write it for them. As a result, a great deal of time and effort was spent writing highly personalized application programs. Because these programs were designed to be used by the author of the program or someone in close proximity to the author, the user benefited directly from the author’s mental model of the program’s operation as well as the author’s knowledge of computers and the programming process. Program effort was spent largely on providing the problem-solving functions. The extra work required to allow ease of learning and use was usually not done. If program structure allowed and time was available, enhancements might be added later in the process to make life easier for the user.
