“…It has long been known that situations where the locally-defined “up and down” are ambiguous or unexpected can elicit disorientation and motion sickness symptoms among astronauts (Nicogossian et al, 1988). It is also known that providing a tactile reference can aid with orientation and performance during spaceflight (Lackner and DiZio, 2000; van Erp and van Veen, 2006; Clément et al, 2007) or piloting of an aircraft (Rupert, 2000; Kelley et al, 2013; Brill et al, 2014). In these cases, body tilt or motion that has not been perceived correctly causes the tactile cue to vibrate much like a rumble strip vibrates a driver who is veering off the road.…”

Astronauts and vestibular patients face analogous challenges to orientation function due to adaptive exogenous (weightlessness-induced) or endogenous (pathology-induced) alterations in the processing of acceleration stimuli. Given some neurovestibular similarities between these challenges, both affected groups may benefit from shared research approaches and adaptation measurement/improvement strategies. This article reviews various past strategies and introduces two plausible ground-based approaches, the first of which is a method for eliciting and assessing vestibular adaptation-induced imbalance. Second, we review a strategy for mitigating imbalance associated with vestibular pathology and fostering readaptation. In discussing the first strategy (for imbalance assessment), we review a pilot study wherein imbalance was elicited (among healthy subjects) via an adaptive challenge that caused a temporary/reversible disruption. The surrogate vestibular deficit was caused by a brief period of movement-induced adaptation to an altered (rotating) gravitoinertial frame of reference. This elicited adaptation and caused imbalance when head movements were made after reentry into the normal (non-rotating) frame of reference. We also review a strategy for fall mitigation, viz., a prototype tactile sway feedback device for aiding balance/recovery after disruptions caused by vestibular pathology. We introduce the device and review a preliminary exploration of its effectiveness in aiding clinical balance rehabilitation (discussing the implications for healthy astronauts). Both strategies reviewed in this article represent cross-disciplinary research spin-offs: the ground-based vestibular challenge and tactile cueing display were derived from aeromedical research to benefit military aviators suffering from flight simulator-relevant aftereffects or inflight spatial disorientation, respectively. These strategies merit further evaluation using clinical and astronaut populations.

“…Vibrotactile displays are proving to be a useful adjunct to visual and auditory displays, as demonstrated in various complex and "event-driven" professional domains such as aviation, navigation, interface design, and healthcare (Hameed, Ferris, Jayaraman, & Sarter, 2009;Jones, Lockyer, & Piateski, 2006;Kelley et al, 2013). Evidence suggests that vibrotactile devices are reliable (Jones et al, 2006), and can be as effective as visual or auditory displays (Ferris & Sarter, 2011;Ngo & Spence, 2010) at alerting clinicians to changes in patient status.…”

Prior investigations of vibrotactile displays suggest they have promise for use in the healthcare domain. This exploratory study forms part of a series exploring the use of an upper arm, continuously informing, vibrotactile display of pulse oximetry for clinicians. The study focused on the effect of vigilance on participants' accuracy and latency for detecting and identifying changes in vital sign levels. Twenty-one participants were tested in a within-subjects design in four blocks of approximately 18 minutes duration each. Two blocks were a low workload condition and the other two blocks a high workload condition. Data were analysed against thresholds of 90% for accuracy and 10 seconds for response latency and workload conditions were also compared for accuracy and latency. Participants' accuracy was not better than 90% and response latency was not shorter than 10 seconds, even in the low workload conditions. Participants were slower to detect changes in the high workload condition, and detection time worsened as the experiment progressed. Taken together, the results suggest that detecting rare events places a high strain on cognition and negatively affects performance. These findings have implications for the use of vibrotactile displays and will guide further investigations into the use of vibrotactile technology in healthcare.

“…In a helicopter study pilots were able to stay closer to a moving target during hover when using a tactile display (than without) and they also rated their situation awareness as higher when they used the tactile display [8]. Curry and Estrada [5] showed that a tactile belt significantly improved drift control during takeoff and hover in helicopters.…”

Brownout during helicopter landing and takeoff is a serious problem and has caused numerous accidents. Development of displays indicating drift is one part of the solution, and since the visual modality is already saturated one possibility is to use a tactile display. The main purpose in this study was to investigate how tactile displays should be coded to maintain or increase the ability to control lateral drift. Two different tactile drift display configurations were compared, each with three different onset rates to indicate the speed of lateral drift. A visual drift display was used as control condition. The results show that best performance is obtained with the basic display with slow onset, and with complex display with constant onset rate. The results also showed that performance with the best tactile drift display configurations was equal to the already validated visual display.
