  1. DSKY: The Display Keyboard

  2. Manual Control • Sidearm controller more controllable in a variety of gravitational fields • Variable control of angular rate allows for a wide range of control, with fine gradation at the low end and a deadband to prevent limit cycles

  3. In-Flight Maintenance “In 1964, if you could get 100 hours MTBF on a piece of electronics, that was a good piece of electronics'' [NEV] • IFM suggested to improve system reliability • I/L study determined it would take 3 years to train astronauts for IFM • Eliminated entirely by component “potting”

  4. Human Factors: Anthropometry and Configuration • display and control arrangement • zero g tethering • general lighting and caution annunciators

  5. Human Factors: Visual and Visual-motor Subtasks • optics (space sextant, scanning telescope, and alignment optical telescope) • computer (display keyboard) • data and data handling

  6. Human Factors:Environmental Constraint Evaluation • pressure suit • zero g • high g • interior illumination • vibration, acoustic noise • gaseous environment • physiologic stress, fatigue
