Abstract:

Two subjects wearing Mark IV pressure suits, under both the pressurized and unpressurized condition, were tested on several performance tasks. The purpose of the study was to provide an evaluation of performance tasks under suit conditions. Results of the study indicated that the tasks can be successfully presented on an oscilloscope under computer control to evaluate performance capability of suited crew members. Two interesting effects identified in the experimental data were related to characteristics of the pressure suit. When pressurized 1 The subjects were hindered in the performance of a tracking task because they were unable to rotate their wrists, and 2 One subject had difficulty operating push buttons, which were separated by 58 in. between edges, because of the characteristics of the gloves included with the Mark IV suit.
