Software development for the Navigator wearable computers

Abstract: "The paper describes experiences in the design and implementation of a wearable computer, Navigator, focusing on software development. Navigator is a wearable computer with head mounted display, speech recognition, wireless telecommunication, and global position sensing. Navigator includes five off-the-shelf boards, three custom boards, and five customized interconnection interfaces. The progression of subsystem development across five software/hardware platforms, each successively closer approximations to the final platform, is described. Cross development platforms allowed software development to proceed before the final hardware was available. The paper concludes with overall design lessons learned and directions for future implementation and research."
