Existing evidence suggests that cybersickness may be clinically different from ¿classic,¿ motion-induced sickness; this evidence was, however, obtained in separate studies that focused on just one of the two conditions. Our aim was to bring clarity to this issue by directly comparing subjective symptoms and physiological effects of motion sickness induced by physical motion (Coriolis cross-coupling) and by immersion in virtual reality (ride on a roller coaster) in the same subjects. A cohort of 30 young, healthy volunteers was exposed to both stimulations in a counterbalanced order on 2 separate days =1 wk apart. Nausea scores were recorded during the exposure, and the Motion Sickness Assessment Questionnaire (MSAQ) was used to profile subjective symptoms postexperiment. Tonic and phasic forehead skin conductance level (SCL) was measured before and during exposure in both stimulation methods. We found that the nausea onset times were significantly correlated in both tests (r 0.40, P 0.03). Similarly, the maximum nausea ratings were significantly correlated during both provocations (r 0.58, P 0.0012). Symptom-profiling with the MSAQ revealed substantial and significant correlations between total symptom scores (r 0.69, P < 0.0001) between each of 4 symptom clusters and between 15/18 individual symptoms assessed in both conditions. Both virtual reality and Coriolis cross-coupling provocations caused an increase in tonic SCL associated with nausea [mean difference (mean diff) 5.1, confidence interval (CI) (2.59, 6.97), P 0.007 and mean diff 1.49, CI (0.47, 7.08), P 0.0001, respectively], with a close correlation between the conditions (r 0.48, P 0.04). This was accompanied by a significant increase in the amplitude of phasic skin conductance transients in both visual stimulation and Coriolis cross-coupling when participants reported maximum nausea compared with no nausea [mean diff 0.27, CI (0.091, 0.63), P < 0.001 and mean diff 0.235, CI (0.053, 0.851), P < 0.006, respectively]. We conclude that symptoms and physiological changes occurring during cybersickness and classic motion sickness are quite similar, at least during advanced stages of these malaises.

A biometrically enabled training solution for the measurement of cognitive overload and threat perception 2019 - 2021

Cognitive load can be defined in a number of ways but is most intuitively understood as the ability of an individual to process information presented to them within a given timeframe. When a decision maker can comfortably process the information provided to them within a given timeframe, cognitive load would be considered low.  In contrast, as the amount of information increases, or the time available to make a decision decreases, or both occur at the same time, cognitive load would increase. For every decision maker, there is a critical point where cognitive load increases to an extent at which no further information can be effectively processed or considered.   When a decision maker has arrived at the critical point where cognitive load reaches its maximum level, a problematic secondary phenomenon develops, which is the loss of a situational awareness. 

 In this research study our primary objective is to demonstrate that cognitive overload can be identified objectively. We will achieve this by developing a real-time mental workload monitoring system.
