Results and Applications of a Space Suit Range-of-Motion Study 891592

The range of motion of space suits has traditionally been described using limited two-dimensional mapping of limb, torso, or arm movements performed in front of an orthogonal grid. A new technique for recovering extravehicular (EVA) space suit range-of-motion data during underwater testing was described in a paper presented by the author at the 1988 conference. The new technique uses digitized data which is automatically acquired from video images of the subject. Three-dimensional trajectories are recovered from these data, and can be displayed using two-dimensional computer graphics. Results of using this technique in a study of the current shuttle EVA suit during underwater simulated weightlessness testing are discussed. Application of the data for use in animating anthropometric computer models is highlighted.
