IWAR'99 Breakout Session:

Leveraging from Human Factors Research

Summary: Bill Miller (WFMiller@nps.navy.mil) / Thad Starner (testarne@cc.gatech.edu

Issues in the transition of augmented reality to avionics applications:

Flow of the discussion:

(These are not necessarily the words spoken by each participant, but it tries to capture the flow of ideas in the session)

Simplicity vs. complexity of display. Necessary is a standardizing of symbology. To present the most important information at the right time. This depends also on the context. Research: overpowering displays, attention. "most people want palmtop with camera". Why do people don't like head mounted displays? Problem: is not custom fitted, doesn't look cool. Helmet mounted displays had same problem. It is necessary to get studies of long term HUD use. Imrpovements needed: variable focus, crispness, better eyesight over time, can handle longer. Characteristics of such display systems: field of view, latency, computational bandwidth, fovea for detail, resolution. Option: to utilize the benefits of spatial and muscle memory for interfaces. "Normal windows desktop icons give no clue of contents." No effort for placement keying memory of contents. Information visualization projects: stuart card, robinson, muscle memory, Bill Buxton work with Alias. Interactions centered around body are remembered better (see SIGGRAPH and thesis at UNC). Filing system versus intelligent agent, . ambient versus serendipitous vversus dialog boxes... a continuum of interruptibility in interface. Utilizing 3D audio interfaces for information location: Furness "virtual cockpit" (Wright Patterson) "daddy your landing gear is up" The Aviation Week and Space Technology issue of 10/18/99 has an article about aviator's assistant.


  • "Helmet-Mounted Displays and Sights" Mordekhai Velger ISBN 0890068224 Artech House Publishers A lot of good psychophysics in one place. 1998. I think everyone interested in HUD's should be familiar with the material in this book.
  • "Head Mounted Displays: designing for the user" James E. Melzer and Kirk Moffitt ISBN 0070418195 McGraw-Hill. 1996 Chapters written by Bill Miller: aerospace database on human factors CD-ROM Brooks Air Force base (Georgia Tech may have it).
  • "AGARD" is standard for sharing research in aviation organization AGARD also standard testing method for equipment (large FOV, night vision goggles).
  • military unclassified tech reports, flight test reports.
