Human-centered design capitalizes on and accommodates human skills in perception, attention, and cognition, while minimizing the opportunities for and effects of human error. This paper describes a mature practical process for accomplishing this goal of human-centered design. Usability is the foundation of this process. The first step in creating a human-centered system is to determine who the operators are, how, where, and what they are using the system for now, and what they would like to use it for in the future. The next step is to set relevant and realistic usability goals for the user interface of the new system. These goals include the time to accomplish the task and error tolerance. The final step is to perform usability testing, starting with a prototype. Many usability issues will become apparent by creating scenarios that 1) exercise a representative sample, if not all, of the operator functions and 2) provide a realistic operational environment for testing. By collecting and analyzing usability data, specific interface features can be evaluated and any mismatch between the design and the operational use will be revealed. Through iterative design improvements the final product will be easy to use and difficult to use incorrectly.","PeriodicalId":335827,"journal":{"name":"17th DASC. AIAA/IEEE/SAE.

Dillard","doi":"10.1109/DASC.1998.741559","DOIUrl":"https://doi.org/10.1109/DASC.1998.741559","url":null,"abstract":"The increased speed with which new technologies are being introduced into the modern aviation operating environment has made it necessary to find new ways of evaluating certification, human factors, operational and safety issues. We no longer have the luxury of an extended development program, followed by an evolutionary period of products maturing into more complex forms, with an extended useful life. Modern technology delivers fully formed products to the marketplace with rapid wide distribution and, in many cases, a limited operating life due to forced obsolescence caused by new advances and technologies. Aviation has always been a technology leader, and this hasn't changed, so the introduction of new communication, navigation, surveillance and display technology is moving forward at a fast pace. Aviation is also a very competitive business, and maximum benefit comes from the early implementation of innovative new products and applications. While some time elements of the product life cycle have changed, critical requirements for validating safety, reliability and system integrity in civil aviation have not. The process of operationally integrating a new technology into an existing, highly complex, costly and potentially hazardous domain, such as airports and aircraft cockpits, demands an exhaustive evaluation of their effects on the existing system, while maintaining safety and performance standards, support logistics and affordability. To shorten the time required for equipment and procedural development, and operational implementation, the use of simulation has grown in importance. Simulation can consist of virtual modeling on a computer workstation, part task devices with actual system hardware and software, or full-mission man-in-the-loop simulators with visual systems and motion. All have their place in the process, and all play a role in shortening development time and cost. We will be looking at the use of full-mission simulators for piloted operational evaluations.","PeriodicalId":335827,"journal":{"name":"17th DASC. AIAA/IEEE/SAE. Digital Avionics Systems Conference.

Ultra-reliable real-time control systems-future trends 超可靠实时控制系统——未来趋势

Future aircraft, spacecraft and other vehicles will require greater use of these types of controls for functions that currently are allowed to fail, fail to degraded operation, or require human intervention in response to failure. Fully automated and autonomous functions will require ultra-reliable control. But ultra-reliable systems are very expensive to design and require large amounts of onboard equipment. This paper will discuss how the use of low-cost sensors with digital outputs, digitally commanded fault-tolerant actuation devices and interconnecting networks of low-cost data buses offer the promise of more affordable ultra-reliable systems. Specific technologies and concepts to be discussed include low-cost automotive and industrial data buses, \"smart\" actuation devices with integral fault masking capabilities, management of redundant sensors, and the fault detection and diagnosis of the data network. The advantages of integrating the control and distribution of electrical power with the control system will be illustrated. The design, installation, and upgrade flexibility benefits provided by an all-digital and shared network approach are presented. The economic benefits of systems that can operate following failure and without immediate repair will be reviewed. The inherent ability of these redundant systems to provide effective built-in-test and self-diagnostics capabilities will be described. The challenges associated with developing ultra-reliable software for these systems and the difficulties associated with exhaustive verification testing will be presented as will additional development hurdles that must be overcome.","PeriodicalId":335827,"journal":{"name":"17th DASC.
