The role that man will play in the space-based servicing of satellites will change with standardization and automation of such operations. This change will permit man to dedicate more of his time in space to tasks that require his unique intellectual, manipulative, and perceptual abilities. However, if history is any indication, man cannot be completely removed from servicing duties because unanticipated servicing operations occasionally will require his direct intervention and control through either extra-vehicular activities (EVA) or teleoperations. As a result, certain minimum user-system interface capabilites must be maintained, no matter how sophisticated future technology becomes. This paper discusses research related to some of the basic human factors problems that will probably always have an impact on space-based teleoperated servicing operations. The implicit warning is that future advanced systems must implement solutions to these problems if humans are to provide effective backup support. Furthermore, the authors believe that there are several critical gaps in our present knowledge of teleoperator human factors that must be closed before such backup operations can be effective. There is a danger that system developers may become so enamored of advanced teleoperator technology that they may fail to provide an adequate user/system interface for backup operations. Human factors issues discussed include: vision systems, control devices and communication time delays. Each issues section concludes with a list of suggested research topics that address gaps in our present knowledge about teleoperator human factors.

NASA is currently working on the Space Station which will be a permanently manned orbiting space laboratory when it becomes operational in the mid 1990's. A part of the Space Station will be a teleoperated robot (telerobot) with arms for grasping and manipulation, feet for holding onto objects, and television cameras for visual feedback. The objective of the work described in this paper is to develop the requirements and specifications for the user-telerobot interface and to determine through research and testing that the interface results in efficient system operation. The focus of the development of the user-telerobot interface is on the information required by the user, user inputs, and design of the control workstation. Closely related to both the information required by the user and the user's control of the telerobot is the user's mental model of the relation of the control inputs and the telerobot's actions.
During off-road navigation, drivers often must make size, distance, and clearance judgments of terrain features and obstacles in order to choose safe navigational routes. These same judgments must be made in the teleoperation of land vehicles using forward-looking television systems. This study evaluated how well subjects perceived size, distance, and clearance using monochrome and color television systems. Thirty-eight subjects (Ss) estimated the size, distance, and separation of two obstacles using video imagery produced by a forward-looking, vehicle-mounted camera. Results indicate that Ss typically overestimated distances, and when in error judging clearance, tended to overestimate the gap between the objects. These biases were expected due to the well documented minification effect of television using standard lenses. More surprising was the somewhat larger bias evidenced by Ss using color versus those using monochrome imagery. This paper will describe the research methodology, the results obtained, potential reasons for the results, discuss the plans for continuing research in this area, and assess the implications these findings may have on teleoperated vehicle design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
