Popis: The overall goal for the design of complex sociotechnical systems is to maintain human-machine system performance. One advanced interface design concept that attempts to do so is the dynamically adaptive interface (DAI). DAI is a computer interface that changes the display or control characteristics of the system, or both, in real time. The goal of DAI is to anticipate informational needs or desires of the user and provide that information without the requirement of an explicit control input by the user. This article explores both theoretical and practical issues in the design of DAIs. The relation of the DAI concept to decision aiding and automation is discussed, and a theoretical framework for design is outlined. A preliminary investigation of the DAI design concept was conducted in the domain of aviation (precision, low-level navigation). Nontraditional controls, such as a force reflecting stick, and displays, such as a configural flight director, were developed to support performance at the task. A standard interface, with conventional controls and displays, a candidate interface, with alternative controls and displays, and an adaptive interface, dynamically alternating between the standard and candidate displays, were evaluated. The results indicate that significant performance advantages in the quality of route navigation were obtained with the candidate adaptive interfaces relative to the standard interface. There were no significant differences between the candidate and adaptive interfaces. The implications of these results are discussed, with special emphasis on their relation to fundamental challenges that must be met for the DAI concept to be a viable design alternative.
