The Conference on human Vision and Electronic Imaging had its origins as three sessions in the 1988 SPIE/SPSE symposium on Electronic Imaging Devices and Systems. These sessions brought together visual psychophysicists and imaging scientists and engineers to explore the relevance of human vision to the design of imaging systems. In the early years of the conference, the focus was on display technology and low-level image coding and rendering. The scope of the conference has grown with the evolution of electronic imaging technology, and the conference today includes papers on visualization, machine vision, digital image libraries, and art. Over the years, the conference has become more focused on truly integrating perception and engineering. We have been proud to see how our community has applied knowledge of perceptual systems to create novel engineeringdesigns, and how knowledge of engineering challenges has led to the identification of novel directions for vision research. This paper will examine the progress of this multidisciplinary field as seen through the lens of this conference, and will speculate on where we are headed.

Current protective and safety clothing and equipment items supplied to U.S. Army helicopter aircrews, have been developed over the years as individual items dictated for the most part by special mission requirements. This lack of an effective, integrated design has resulted in equipment items that can be a physical burden to wear and cause a degradation in operational performance. The Air Warrior program is a U.S. Army effort that seeks to correct some of the problems with the current equipment ensembles and eventually field the next generation of aircrew-mounted mission equipment. This future equipment will provide a fully integrated protective ensemble that will enhance the capabilities and performance of the aircrew. In conjunction with the Air Warrior program, the US Army Research Laboratory (ARL) human Research and engineering Directorate (HRED) developed a modeling and simulation approach to examine the encumbrance of current helicopter aircrew clothing and equipment. This approach used 3D graphical anthropometric human figure models fitted with digitized Aviation Life Support Equipment (ALSE) as a means of examining the operational impact of this gear on the aircrew. Results obtained from this method were compared to data collected with a Motion Analysis optical tracking system on actual subjects wearing the same ALSE items. Based on the limited data collected, this method shows promise for evaluating future clothing and equipment ensembles.

The modeling of human work is ubiquitous in the cognitive engineering community. modeling can take many diverse forms, but its goal is always the same: to provide designers with a deeper understanding of the needs of human operators. This understanding becomes ever more critical as work domains increase in complexity because the capability of designers to anticipate all of the needs in all possible contexts becomes less tenable without modeling tools. Why, then, is there such a proliferation of work analysis techniques? Even more importantly, which modeling techniques are most useful for what types of design problems? In this symposium, several papers will be presented describing the application of various modeling techniques to the design of complex work environments. An emphasis will be placed on identifying the modeling techniques that are useful, or not useful, for various types of application domains and for different design goals. The strengths of integrated modeling techniques will be examined as compared with their increased costs. The various presenters will provide guidance for the selection of design problems, the application and payoffs from the modeling effort, and the use of results for design.
