Pilot Behavior

When a flight crew has situation awareness they have a complete and accurate understanding of the physical, temporal and emotional environments in which they are situated. This allows the flight crew to interpret and evaluate elements or events in the environment in which they are situated and determine the risks associated with these events and an appropriate strategy to minimize and manage these risks. This paper describes the architecture for an intelligent software agent which assesses a flight crew’s situation awareness through the observation of a pilot’s eye movements. The agent perceives pilot behavior using a proprietary eye tracking device. This behavior is compared to a behavior database to decide whether the behavior of the pilot is appropriate or inappropriate in terms of the safety of the flight. The flight crew is alerted if the behavior is judged to be consistent with the flight crew losing situation awareness.

Traditional Approaches

Optokinetic nystagmus (OKN) is an involuntary eye movement induced by motion of a large proportion of the visual field. It consists of a “slow phase (SP)” with eye movements in the same direction as the movement of the pattern and a “fast phase (FP)” with saccadic eye movements in the opposite direction. Study of OKN can reveal valuable information in ophthalmology, neurology and psychology. However, the current commercially available high-resolution and research-grade eye tracker is usually expensive. Methods & Results: We developed a novel fast and effective system combined with a low-cost eye tracking device to accurately quantitatively measure OKN eye movement. Conclusions: The experimental results indicate that the proposed method achieves fast and promising results in comparisons with several traditional approaches.

Considers the influence of the degree of extraversion on the perception of digital information by aviation operators. The analysis of the results of solving the Schulte tables by the test subjects on the NS-Psychotest hardware complex based on the recording of the eye track, performed using a stationary eye tracking device RED250mobile eye tracking device was carried out. While performing the search function, the number of saccadic movements, their amplitude, and the search time for a given digital value were registered. It has been revealed, that introverts during realization eyes search function perform less saccadic movements and spend less time on it than extraverts do. Significant differences have been found during resolving search tasks depending on degree of extraversion. Some interconnections of extension the latent period of the saccade with complication of solving process the cognitive problem were also found. It was found out, that increase in speed of saccadic movements of eyes leads to low efficiency of results of search task execution. Results of conducted research emphasize value of individual approach to medical flight service taking into account psychological features of flight crew in conditions of rapid progress in aviation technologies and means of visualisation of flight information. The obtained data reveal some features of information perception by operators of complex ergatic systems, the study of which in the future will help to maintain the reserves of attention in a continuous stream of incoming data, and thereby reduce the load on the visual analyzer and increase the reliability of professional activities of flight crew.

Driving Task

We exhaustively review the published research on eye movements during real-world night driving, which is an important field of research as fatal road traffic accidents at night outnumber fatal accidents during the daytime. Eye tracking provides a unique window into the underlying cognitive processes. The studies were interpreted and evaluated against the background of two descriptions of the driving task: Gibson and Crooks’ (1938) description of driving as the visually guided selection of a driving path through the unobstructed field of safe travel; and Endsley’s (1995) situation awareness model, highlighting the influence of drivers’ interpretations and mental capacities (e.g., cognitive load, memory capacity, etc.) for successful task performance. Our review unveiled that drivers show expedient looking behavior, directed to the boundaries of the field of safe travel and other road users. Thus, the results indicated that controlled (intended) eye movements supervened, but some results could have also reflected automatic gaze attraction by salient but task-irrelevant distractors. Also, it is not entirely certain whether a wider dispersion of eye fixations during daytime driving (compared to night driving) reflected controlled and beneficial strategies, or whether it was (partly) due to distraction by stimuli unrelated to driving. We concluded by proposing a more fine-grained description of the driving task, in which the contribution of eye movements to three different subtasks is detailed. This model could help filling an existing gap in the reviewed research: Most studies did not relate eye movements to other driving performance measurements for the evaluation of real-world night driving performance.

Head-mounted eye tracking has been fundamental for developing an understanding of sporting expertise, as the way in which performers sample visual information from the environment is a major determinant of successful performance. There is, however, a long running tension between the desire to study realistic, in-situ gaze behaviour and the difficulties of acquiring accurate ocular measurements in dynamic and fast-moving sporting tasks. Here, we describe how immersive technologies, such as virtual reality, offer an increasingly compelling approach for conducting eye movement research in sport. The possibility of studying gaze behaviour in representative and realistic environments, but with high levels of experimental control, could enable significant strides forward for eye tracking in sport and improve understanding of how eye movements underpin sporting skills. By providing a rationale for virtual reality as an optimal environment for eye tracking research, as well as outlining practical considerations related to hardware, software and data analysis, we hope to guide researchers and practitioners in the use of this approach.

The appearance of food provides certain expectations regarding the harmonization of taste, delicacy, and overall quality, which subsequently affects not only the intake itself but also many other features of the behavior of customers of catering facilities. The main goal of this article is to find out what effect the visual design of food (waffles) prepared from the same ingredients and served in three different ways—a stone plate, street food style, and a white classic plate—has on the consumer’s preferences. In addition to the classic tablet assistance personal interview (TAPI) tools, biometric methods such as eye tracking and face reading were used in order to obtain unconscious feedback. During testing, air quality in the room by means of the Extech device and the influence of the visual design of food on the perception of its smell were checked. At the end of the paper, we point out the importance of using classical feedback collection techniques (TAPI) and their extension in measuring subconscious reactions based on monitoring the eye movements and facial expressions of the respondents, which provides a whole new perspective on the perception of visual design and serving food as well as more effective targeting and use of corporate resources.

Hiking is a very popular outdoor activity, and has led to an exponential increase in the number of visitors to natural spaces. The objective of this study was to analyze the circulation pattern of visitors to the Caminito del Rey trail, based on the three zones into which the trail can be divided. The sample consisted of 1582 hikers distributed into three different profiles. Of these, 126 utilized an eye-tracking device during the hike, while, for the rest (1456), only their travel speed along the trail was recorded. The use of eye tracking devices identified a greater number of interesting landscapes located in zones 1 and 3 of the trail, and it was observed that the mean travel speed was greater for zone 2 (42.31 m/min) (p < 0.01). Additionally, when the three different visitor profiles were analyzed, significant differences were found between the mean travel speeds according to sectors (p < 0.05). This information is crucial for more efficient management of the trail, as it allows for the development of measures to control and regulate the flow of visitors according to zone, and the design of additional strategies to increase the awareness of the hiker about specific areas of the hike.

Noncanonical Form

Abstract Comprehending idioms (e.g., bite the bullet) requires that people appreciate their figurative meanings while suppressing literal interpretations of the phrase. While much is known about idioms, an open question is how healthy aging and noncanonical form presentation affect idiom comprehension when the task is to read sentences silently for comprehension. Here, younger and older adults read sentences containing idioms or literal phrases, while we monitored their eye movements. Idioms were presented in a canonical or a noncanonical form (e.g., bite the iron bullet). To assess whether people integrate figurative or literal interpretations of idioms, a disambiguating region that was figuratively or literally biased followed the idiom in each sentence. During early stages of reading, older adults showed facilitation for canonical idioms, suggesting a greater sensitivity to stored idiomatic forms. During later stages of reading, older adults showed slower reading times when canonical idioms were biased toward their literal interpretation, suggesting they were more likely to interpret idioms figuratively on the first pass. In contrast, noncanonical form presentation slowed comprehension of figurative meanings comparably in younger and older participants. We conclude that idioms may be more strongly entrenched in older adults, and that noncanonical form presentation slows comprehension of figurative meanings.

Abstract. To better understand the process of responding to the Conditional Reasoning Test for Aggression (CRT-A) and its implication for the test's use in personnel selection, we conducted two lab studies in which we compared test scores and eye movements of participants responding honestly and faking the test. Study 1 results showed that, although participants might try to respond differently to the CRT-A while faking, it remains an indirect and unfakeable measure as long as the test's purpose is undisclosed. Study 2 showed that revealing the true purpose of the CRT-A diminishes the test's indirect nature so the test becomes fakeable, solving it requires less attention and participants direct their eyes more to response alternatives congruent with the presentational demands.
