“…The findings suggest that tactile alerts are a very effective means of notifying pilots of a potential conflict: they were detected in 100% of all cases, and the accuracy of the evasive maneuver ranged from 89% to 100% in the various conditions. This result confirms findings from earlier studies (e.g., Lawson et al, 2015;Ho, Gray and Spence, 2014;Meng, Spence, 2015) showing that tactile cues are well suited for conveying spatial and directional information.…”

“…In particular, the introduction of tactile feedback (i.e., vibrations presented to the skin) has been shown to help offload the already over-burdened visual and auditory channels (Wickens, 1991;van Veen & van Erp, 2001). Tactile information presentation leads to shorter response times than auditory or visual feedback (Lu et al, 2011), and tactile interfaces are well suited for supporting a number of functions, such as delivering simple messages and providing spatial orientation and guidance (Jones & Sarter, 2008, Lawson et al, 2015Lindeman et al, 2004).…”

Future aviation operations will require pilots to assume new tasks, such as self-separation. Tactile displays are a promising means of supporting this task. They are well suited for presenting spatial information and offload the heavily taxed visual and auditory channels. This experiment assessed the effectiveness of tactile spatial alerts for notifying pilots of an aircraft intruding on their flight path during Closely Spaced Parallel Approaches. Two alerting strategies (single-stage vs. graded) and two alert types (status vs. command) were compared. 19 pilots had to fly a series of approaches, detect tactile alerts and perform evasive maneuvers. The detection rate for tactile alerts was 100%. Graded and status alerts led to the highest response accuracy (100% and 98%, respectively). Response times were faster for command alerts and during manual flight. These results indicate that tactile displays are effective for conveying spatial information and can help prevent collisions in future aviation operations.

Research into sensory substitution systems has expanded, as alternative senses are utilized in real-time to afford object recognition or spatial understanding. Tactile stimulation has long shown promise as a communicatory strategy when applied unobtrusively to the redundant surface areas of the skin. Here, a novel belt, integrating a matrix of macro fiber composites, is purposed to deliver tactile stimuli to the abdomen. The design and development of the belt is presented and a systematic experimental study is conducted to analyze the impact of frequency and duty cycle. The belt is a beta precursor to a soft haptic feedback device that will enable situational awareness and obstacle avoidance through the localization of tactile stimulation relative to a body-centric frame of reference in a local environment.
