  1. Requirements Analysis Domain: Submarine Warfare Goal: Launch Torpedoes • OwnshipReadinessTask – Criteria that must be met concerning your ownship. 11. FiringTask – Criteria that must be met concerning the situational relationship between ownship and target. Aft the beam? In the baffles?

  2. Empirical Test Criteria I. Ownship Readiness Task: • Speed<=9.5 KTS • Dive Angle < 3 Degrees • Turn Rate<= 1 Degree per minute II. Firing Task: • Ownship AFT the beam (We are sneaking up from behind) • Ownship in baffles (Cone defined as 15 degrees either side of a line extending longitudinally through the target back along its direction of travel) • Distance <40NM • Torpedo envelopes cover 50% of 90% escape envelope

  3. Escape Envelope 90% Enable Point T Torpedo Envelope O – ownship T - target

  4. 1. AFT the Beam 2. In Baffles 3. Distance < 40NM 4. Torp. Envelopes >50% Ownship- in the baffles T 15° O 15 ° O- ownship T- Target

  5. Additional Requirements • Make accurate decisions • Make fast decisions • Keep one’s attention focused on critical information. • User acceptance of the interface (i.e. user friendliness, likeability).

  6. Conceptual Hypothesis: Displays that promote cognitive flexibility will enhance user-computer performance. Operational Hypothesis: Multiple coding ofdata will result in better user-computer performance than when data is only in one form.

  7. Conceptual Hypothesis: By limiting data-driven tasks, user-computer performance will be enhanced. Operational Hypothesis: Using statusindicators to limit data-driven tasks will result in better user-computer performance than when status indicators are not used to limit data-driven tasks.

  8. Conceptual Hypothesis: If information load is minimized in order to allow human processing to comfortably absorb all displayed data, user-computer performance will be enhanced. Operational Hypothesis: Displays that include only that information needed by theoperator at a given time will result in better user-computer performance than displays that include additional information. Operational Hypothesis: An interface with judicious redundancy will result in better user-computer performance than an interface with unnecessary redundancy.
