Box plot of physiological measurements and eye-tracking activations. Several physiological parameters were recorded during objective tasks completion. These parameters were evaluated while detecting statistically different values, as compared to baseline. Each of these detections (‘activations’) is numerically integrated in order to evaluate the number of physiological variations in response to tasks. These activations are considered to be adequate stress indicators. The number of activations is represented as median and interquartile. Dotted line is mean of activations for all ventilators, during all tests. For all parameters, our reference value depicted significantly fewer activations, thus validating our experimental concept. Significant papillary diameter, respiratory rate and tidal volume activations were observed for several devices (at least V500 and Servo-U). *p value <0.05; # p value <0.005; § p value <0.0005
