In aviation maintenance and inspection, work documents are critical to safety, as they act as both production control devices and job aids for mechanics and inspectors. Based on an analysis of the current state of documentation in aviation maintenance, there was a clear need to help document designers/writers utilize good human factors practice. Design guidelines were developed and tested (Patel et al, 1994) and then made accessible through a Visual Basic window, called the Documentation Design Aid or DDA, available on-screen while writing a procedure. This DDA was tested for usability by writers and for comprehension of the documents produced. A number of different evaluations showed that the DDA reduced comprehension errors significantly. The DDA is now available via a WWW site for users to download and use.

The purpose of this research is to aggregate and discuss the validity of challenges and design guidelines regarding industrial Virtual Reality (VR) training applications. Although VR has seen significant advancements in the last 20 years, the technology still faces multiple research challenges. The challenges towards industrial VR applications are imposed by a limited technological maturity and the need to achieve industrial stakeholders' technology acceptance. Technology acceptance is closely connected with the consideration of individual user requirements for user interfaces in virtual environments. This paper analyses the current state-of-the-art in industrial VR applications and provides a structured overview of the existing challenges and applicable guidelines for user interface design, such as ISO 9241-110. The validity of the identified challenges and guidelines is discussed against an industrial training scenario on electrical safety during maintenance tasks.

The Right

Human Factors and ergonomics professionals are often asked to “show” how their research has affected on-the-job human performance. They are asked to show measurable changes in human effectiveness and efficiency at work. There is always the demand for HF&E researchers to create procedures and tools that can guide non-human factors personnel to make the “right” human-centered decisions. This symposium will show and distribute such tools that have been designed and tested in an aviation maintenance environment. For over six years now, the Federal Aviation Administration Office of Aviation Medicine has conducted an extensive research program centered on human factors in aviation maintenance and inspection. The research program has earned a reputation of demonstrating a “hands-on” understanding of aviation maintenance and maintaining a close working relationship with all segments of the industry. The symposium will begin with an overview of FAA-sponsored research results applied to aviation maintenance and safety over the past six years. In the second paper the Human Factors Guide for Aviation Maintenance, completed in 1995, will be described. The third presentation will demonstrate a CD-ROM version of the Guide. The presentation shall also discuss human-computer interface issues pertinent to developing interactive multi-media information systems. The final presentation will show a multi-media software package to conduct ergonomics audits in a variety of industrial environments. The system has evolved from three years of ergonomics audit research in aviation maintenance workplaces. Each of the session presentations will demonstrate and distribute HF&E tools to session attendees.

The contribution of this research is to argue that truly creative patterns for interaction within cultural heritage contexts must create situations and concepts that could not have been realised without the intervention of those interaction patterns. New forms of human-computer interaction and therefore new tools for navigation must be designed that unite the strengths, features, and possibilities of both the physical and the virtual space. The human-computer interaction techniques and mixed reality methodologies formulated during this research are intended to enhance spatial cognition while implicitly improving pattern recognition. This research reports on the current state of location-based technology including Mobile Augmented Reality (MAR) and GPS. The focus is on its application for use within cultural heritage as an educational and outreach tool. The key questions and areas to be investigated include: What are the requirements for effective digital intervention within the cultural heritage sector? What are the affordances of mixed and augmented reality? What mobile technology is currently being utilised to explore cultural heritage? What are the key projects? Finally, through a series of case studies designed and implemented by the author, some broad design guidelines are outlined. The chapter concludes with an overview of the main issues to consider when (re)engineering cultural heritage contexts.

Human Factors Research

The Aloha Airlines B-737 accident in 1989 prompted a general evaluation of aviation maintenance and inspection practices. A consistent finding from the Aloha analyses was that human-factors-related issues played a significant role in the accident. In the intervening period, the FAA Office of Aviation Medicine (AAM) has sponsored a wideranging, applied human factors research program. The Human Factors Guide for Aviation Maintenance (the Guide) is the primary vehicle for channeling the results of the AAM's research program into the aviation user community. This paper describes the development process of the Human Factors Guide for Aviation Maintenance. We include a discussion of how the existing base of research results has been made accessible and, more importantly, usable to aviation maintenance supervisors and inspectors. We also describe the considerations related to widely disseminating the information and guidance contained in the Guide. We believe this to be the first time that detailed human factors guidance from such a broad topical range has been tailored to a particular, applied, user domain.

AbstractRecent research has focused on finding ways to control hysteresis of dynamic comparators. The current proposed techniques are based on either geometrical dimension adjustment or digital control. The first case does not allow for post fabrication control, while the second has limited accuracy. This paper presents a new dynamic comparator design with external hysteresis adjustment using an analog voltage. This is achieved by proposing an architecture including control devices with a specific sizing. This is performed with no significant increase of the design complexity, keeping the power consumption as low as possible. The design is analyzed, showing that the proposed solution allows accurate hysteresis adjustment without affecting the inherent circuit properties. The dynamic comparator is also implemented using a 180 nm commercially available CMOS technology. The results show that a variation of 550 mV of the control voltage allows an accurate hysteresis adjustment ranging from 0 to 40 mV, according to the input conditions. Moreover, the simplicity of the circuit in conjunction with the use of dynamic technology have allowed the best performances to be achieved compared to the current state of the art, in terms of energy with an FoM equal to 116 fJ/decision and silicon area of 180 µm2 .

Since built heritage continues to teach contemporary societies valuable lessons about traditional building practices among other substantial matters, its protection from environmentally insensitive development is important. The reconciliation of heritage conservation and development, therefore, is an appropriate research topic. This article aims at contributing to the global discourse on that topic, which is primarily supported by UNESCO and ICOMOS. It does so by evaluating the success of criteria in guiding the design and assessment of contemporary interventions in historic places. The purpose is to determine whether criteria, which usually come in the form of standards and/or design guidelines, hold the key to thoughtful change in historic places. To achieve this purpose, the present author first gives an overview of the current state of knowledge on the topic, then analyzes major scholarly literature to identify the strengths and weaknesses of criteria and finally suggests other avenues worth exploring. As a result of this qualitative research, readers would gain a better understanding of the background, questioning and principles that should frame new architecture in existing urban fabric.

In the daily operation process of airlines, aviation machinery maintenance and inspection work play an important role. At present, the quality of life of the people in our country is constantly improving. In daily travel, we have not only used cars, trains and other means of transportation, but also started to choose airplanes as the first choice in a higher frequency. In recent years, with the improvement of living standards, more and more people choose to travel during holidays. Therefore, the traffic volume of aviation aircraft is increasing year by year, but it also increases the risk of aviation aircraft failure, so it is particularly important to do a good job in the maintenance and inspection of aviation machinery. In this paper, according to the current situation of aviation machinery maintenance and inspection, put forward targeted improvement measures to ensure the safety and stability of China’s aviation aircraft operation.
