Tactile cues for orienting pilots during hover over moving targets.

Area of Science:

• Aviation psychology
• Human-computer interaction
• Sensory substitution

Background:

• Tactile sensory information can augment pilot awareness without increasing cognitive load on visual and auditory systems.
• Simulated helicopter extractions over moving targets were used to assess tactile cueing efficacy.
• Conditions included pilot state (rested/fatigued) and visual environment clarity (clear/degraded).

Purpose of the Study:

• To evaluate the effectiveness of a tactile cueing system for target orientation in helicopter pilots.
• To determine if tactile cues improve performance in simulated hover maneuvers.
• To assess the impact of fatigue and visual conditions on tactile cue efficacy.

Main Methods:

• A mixed-model 2(4) factorial design was used with 16 rated aviators.
• Variables included training amount, pilot state, visual environment, and tactile cue belt activation.
• Flights were conducted in a UH-60 simulator over a moving target.

Main Results:

• Pilots maintained closer proximity to the target with the tactile system active (31.14 ft) versus inactive (36.33 ft).
• Situation awareness was rated higher when the tactile system was utilized.
• The tactile system demonstrated effectiveness across different conditions.

Conclusions:

• The tactile cueing system is effective in providing directional information for helicopter pilots.
• It supports sustained pilot performance during hover maneuvers over dynamic targets.
• Tactile feedback offers a viable method for enhancing pilot situational awareness.
