ASTRO: an optimized human-computer interface for satellite control network scheduling

It is shown that the network scheduling task for satellite control has grown in complexity until the traditional method of using a paper chart representation is inadequate. The development and user evaluation of a semiautomated network scheduling system incorporating a synergistic human-computer interface is described. The interface consists of a large-screen color display, voice input/output, a sonic pen pointing device, a touchscreen color CRT, and a standard keyboard. ASTRO was managed as a rapid prototype project, and frequent user feedback guided the design process. The evaluations indicated a high level of user satisfaction with ASTRO overall, and its interface in particular.<
