Title: [abstract] A NOVEL INTERFACE TO PROVIDE POSITION AND MOTION CUES IN THE UNDERSEA ENVIRONMENT
Author: Rupert, AH; Raj, AK
Abstract: BACKGROUND: Under normal terrestrial conditions, perception of position and motion is determined by central nervous system integration of concordant and redundant information from multiple sensory channels (somatosensory, vestibular, visual), which collectively yield veridical perceptions. Both the somatosensory (skin, muscle and joint) and visual information channels are frequently compromised in the undersea environment. The U.S. Navy recently funded a program to improve spatial orientation and situation awareness of personal operating in sensory deprived/compromised environments by means of a haptic display. METHODS: A series of prototype devices were constructed to determine whether blindfolded subjects could maintain normal orientation and control of platforms using tactile cues. Multiple tactors, placed in columns and rows, were embedded in a torso suit to give an awareness of roll and pitch to blindfolded operators of closed loop simulators and aircraft. A gyro sensor provided digital position and motion information. RESULTS: Six subjects learned within 30 min how to ascertain the pitch and roll of the platform using tactile cues. Subjects, with practice, could recover simulators and aircrafts from unusual attitudes while deprived of all visual orientation cues. CONCLUSION: Tactile displays may be able to improve the orientation and situational awareness of divers and operators of undersea platforms. The ongoing development of improved tactors for the rigors of the underwater environment will facilitate the transition of this technology to the military and civilian diving communities.
