“…Flight in general can be divided into phases of en route, approach, and taxiing. A number of human factor studies have been conducted to investigate pilots' behaviours in such phases as en route and approach (33,42,43,45) . On the contrary, taxiing, as a complex and dynamic process, has been less studied (46)(47)(48) .…”

Predicting mental workload of pilots can provide cockpit designers with useful information to reduce the possibility of pilot error and cost of training, improve the safety and performance of systems, and increase operator satisfaction. We present a theoretical model of mental workload, using information theory, based on review investigations of how effectively task complexity, visual performance, and pilot experience predict mental workload. The validity of the model was confirmed based on data collected from pilot taxiing experiments. Experiments were performed on taxiing tasks in four different scenarios. Results showed that predicted values from the proposed mental workload model were highly correlated to actual mental workload ratings from the experiments. The findings indicate that the proposed mental workload model appears to be effective in the prediction of pilots’ mental workload over time.

“…As a critical component of the indoor environment, lighting is closely associated with humans, for example, visual comfort and overall satisfaction of occupants. 1,2 Most office workers spend at least 8 h indoors in an artificial lighting environment with little or even no natural lighting. 3,4 Indoor environments lacking natural light were found to be associated with stress, 5 moods, 6 circadian rhythm disorder 7,8 and inhibition of productivity 9,10 in workspace.…”

Most people today stay in a constant artificial lighting environment for a long time. Lack of sufficient daylight exposure may lead to circadian, sleep or mental problem. Dynamic lighting is an effective countermeasure in consideration of its dynamicity. However, besides its changeability, whether the daylight simultaneousness of dynamic lighting has a beneficial effect is unclear. A lab-based study was carried out to explore the effect of Daylight-Simulcasted Dynamic Lighting (DSDL), which simulates the simultaneous information of daylight conveyed by its variation. A reversed pattern of DSDL (Re-DSDL) was also introduced as one of the test conditions for comparison. The within-subject experiment was performed by 24 participants in four conditions: two dynamic lighting patterns (DSDL and Re-DSDL) in two periods (dawn and dusk). The dependent variables were psychological states, physiological indicators and cognitive performance. The results showed that DSDL brought greater benefit to the psychological state than Re-DSDL in general. During dawn, participants experienced less anger and depression in DSDL than in Re-DSDL; during dusk, participants experienced less anger and vigour in DSDL than in Re-DSDL. DSDL also had a significant effect on some of the physical indicators compared with Re-DSDL, but no effect on cognitive performance.

“…Yang et al explored the transient effects of extreme weather on pilots' visual behavior during flight and demonstrated that pulse-changed and step-changed lighting can result in the temporary visual impairment of pilots. 8,9 Rodriguez and Pattini 10 investigated the influence of ambient lighting with a large glare light source on the display VP. The results showed that memory ability decreased significantly as the glare intensity increased.…”

Self-luminous display devices are essential in various working environments, such as aircraft cockpits and the driver cab of vehicles and trains, where the external light environment varies drastically. Owing to the significant illumination changes, auto-adjusted display luminance based on ambient lighting is necessary for drivers to work efficiently and comfortably. This study proposes a display dimming model based on three dimensions of ergonomic testing, consisting of visual performance (VP), visual comfort (VC), and visual fatigue (VF). Five ambient illuminances, each combined with five display luminance levels, form a total of 25 conditions demonstrated in this experiment. Using a within-subject design, ten observers experienced all the combination conditions. The experiment employs the Anfimov table to test the VP, VC scale to evaluate VC, and VF scale to assess VF. Based on the experimental results, sub-models are constructed to clarify the characteristics of each dimension (VP, VC, and VF). Subsequently, the analytic hierarchy process is employed to construct an evaluation system by calculating the weight of each dimension in the total score. Finally, exponential fitting is utilized to build a widerange display dimming model, which explicitly describes the inherent connection of complex light environment matching. © The Authors.
