Appendix a -evolutions

During the research for this dissertation, wearable computers have evolved from very simple and slow 2D graphics to highly detailed 3D rendering systems capable of video overlay, texture mapped triangles, and the ability to render millions of triangles per second for realistic AR output. As discussed in the previous chapter, this evolution process is ongoing as various devices are improved by their respective manufacturers. This appendix discusses the numerous mobile outdoor AR systems that I have constructed at key points in their development, broken down into the equipment that was used, how it was mounted onto the user, and the software that was developed for the platform. Since these three categories were not all changed at the same time (the same software may have been used with multiple types of equipment), platforms are described at various important milestones of development.
