This paper describes a user-centred design process that has been used to develop an innovative simulator for research into motorcycle ergonomics and rider human factors. Building on initial user requirements and user experience elicitation exercises, an evaluation was conducted to investigate specific issues associated with simulator fidelity. An experimental approach was employed to examine the physical and functional fidelity of the simulator. Using different steering and visual feedback configurations, a battery of objective and subjective dependent variables were analysed including: user perceptions and preferences, rider performance data, rider workload, rider comfort issues and the first evaluation of simulator sickness for a motorcycle simulator. The results indicated that across a number of measures, aspects of functional fidelity were considered more important than the physical fidelity of the simulator. This evaluation takes the development of the simulator a stage further and the paper provides recommendations for future improvements.

We introduce a theoretical framework and practical algorithms for replacing time-coded structured light patterns with viewpoint codes, in the form of additional camera locations. Current structured light methods typically use log(N) light patterns, encoded over time, to unambiguously reconstruct N unique depths. We demonstrate that each additional camera location may replace one frame in a temporal binary code. Our theoretical viewpoint coding analysis shows that, by using a high frequency stripe pattern and placing cameras in carefully selected locations, the epipolar projection in each camera can be made to mimic the binary encoding patterns normally projected over time. Results from our practical implementation demonstrate reliable depth reconstruction that makes neither temporal nor spatial continuity assumptions about the scene being captured.

XVision is a software system for image processing research, education and applications. Xyvision utilizes the X Window System Version 11, which provides a network transparent windowing environment and software portability. Xyvision is designed to facilitate: data and algorithm exchange of new computer vision/image processing techniques,image processing training and education,development of turn key vision solutions for various application areas (automation, medicine, biology, astronomy, etc).XVision is a comprehensive system because it supports generation of new programs (extendibility), and integration, maintenance, modification and documentation of existing programs; and it includes: three user interfaces; a menuing system, a quick command line interface that can be customized and a standardized UNIX‡-like command line interface. A visual programming language, xvglyph, is under development.tutorials, manual pages, experiments, automated demonstrations and other supplemental documentation.an image processing library written in C,interactive image display and enhancement, image editing and creation, 2D, 3D, and contour plotting, and data creation/display via user specified functions.The Xyvision project started in February of 1987 with its first release in August of 1987. This paper describes the second version which incorporates changes suggested by many of the users (over 30 different institutions) of Xyvision Version 1.0 [1]. One of the most important design goals of the Xyvision project is to provide for easy growth and extendibility. This has been accomplished by clearly defining software levels, software systems and their standard interfaces, and by providing programming tools and a variety of user interfaces for the Xyvision user/maintainer.
