Paper Abstract

Terrestrial orientation and navigation information is provided by three or more redundant, concordant, veridical, and independent sources of sensory information: the skin- muscle-joint somatosensory system, the inner ear vestibular apparatus, and the visual system. The frequent absence of contact with the bottom and the buoyancy provided by water render the skin-muscle-joint system ineffectual as a reliable source of sensory information. A novel deice, utilizing the intuitive nature of the tactile/haptic system, has been developed to enhance the orientation performance of personnel in sensory deprived underwater environments. The tactile situation awareness system (TSAS) consists of senors providing orientation, guidance, and or communication information to a collection of electromechanical stimulators held in close contact with the skin. In preliminary test, divers equipped with TSAS or traditional visual displays swam a triangular course to evaluate the possible benefits of tactile displays for use in the very shallow water diving environments. The TSAS permitted divers to navigate more accurately and offered information at a lower level of cognitive effort, thereby permitting divers to devote more attention to essential mission-related tasks.
