Eye Tracking Erkenntnisse in Human Factors Q3 2024

With the explosive growth of multimedia streaming services and virtual reality devices, omnidirectional video (ODV) is becoming increasingly popular in practical applications. However, streaming the entire ODV with high definition and high frame rate induces a waste of bandwidth. The tile-based viewport adaptive streaming provides a solution to overcome volatile network conditions, while the scheme would lead to quality adaptation when the network changes dynamically. In this paper, we focus on investigating how the human visual quality of experience (Qo...Mehr anzeigen

This investigation seeks to elucidate the influence of monocular and binocular vision on shooting behaviors, with an emphasis on evaluating shooting precision, the rapidity of aiming responses, and two ocular metrics: the ratio of saccade duration and the mean peak saccade velocity. Findings reveal that monocular aiming surpasses binocular aiming in terms of shooting accuracy, as monocular aiming enhances the shooter's focus on target details. Binocular aiming has a shorter aiming response time in rapid response shooting at multiple targets. The proporti...Mehr anzeigen

Due to the effects of low-pressure and hypoxic environments at high altitudes, drivers in high-altitude areas exhibit increased perceived reaction times, leading to challenges in accurate speed estimation and handling judgment. This study aims to quantitatively analyze the impact of plateau environments on operating speeds at interchange exit ramps. Utilizing a UC/win-road simulator, six scenarios of expressway exit ramps were constructed. The simulation experiments involved 50 participants (35 males, 15 females) from Nanjing, China (altitude of 50 m) an...Mehr anzeigen

Modern aircraft cockpit system is highly information-intensive. Pilots often need to receive a large amount of information and make correct judgments and decisions in a short time. However, cognitive load can affect their ability to perceive, judge and make decisions accurately. Furthermore, the excessive cognitive load will induce incorrect operations and even lead to flight accidents. Accordingly, the research on cognitive load is crucial to reduce errors and even accidents caused by human factors. By using physiological acquisition systems such as eye...Mehr anzeigen

Integrating Artificial Intelligence (AI) and drone technology into bridge inspections offers numerous advantages, including increased efficiency and enhanced safety. However, it is essential to recognize that this integration changes the cognitive ergonomics of the inspection task. Gaining a deeper understanding of how humans process information and behave when collaborating with drones and AI systems is necessary for designing and implementing effective AI-assisted inspection drones. To further understand human-drone-AI intricate dynamics, an experiment...Mehr anzeigen

Physical fatigue is a frequent factor in construction workplaces that threatens workers’ safety. This study examines whether fatigue alters visual search patterns adopted by workers during hazard identification, thereby affecting identification performance. Subjects (𝑛=24) were exposed to four physical activity levels (nonfatigue, low fatigue, medium fatigue, and high fatigue) and then performed hazard identification tasks in a panoramic virtual reality context, with their search patterns being reflected by eye-movement metrics. The results show that ph...Mehr anzeigen

We present CognitIDE, a tool for collecting physiological measurements, mapping them to source code, and visualizing them directly within IntelliJ-based Integrated Development Environments (IDE)s. CognitIDE facilitates the setup and conduction of empirical studies evaluating the relationships between software artifacts and physiological parameters. Corresponding measurements enable researchers to evaluate, for example, the cognitive load software developers are experiencing. Our tool lets study participants use IDEs in a natural way while eye gaze, furth...Mehr anzeigen

Predicting situational awareness (SA) during non-driving-related tasks is critical for improving takeover performance. Although studies have focused on SA prediction based on binary classification, the interpretability of such prediction models is limited, thereby leading to inadequate coverage of SA and suboptimal model efficiency. Therefore, in this study, an interpretable prediction framework based on Extreme Gradient Boosting (XGBoost) and Shapley Additive Explanations (SHAP) was developed for multi-class SA prediction. This model first integrates va...Mehr anzeigen

The rising frequency of natural disasters demands efficient and accurate structural damage assessments to ensure public safety and expedite recovery. Human error, inconsistent standards, and safety risks limit traditional visual inspections by engineers. Although UAVs and AI have advanced post-disaster assessments, they still lack the expert knowledge and decision-making judgment of human inspectors. This study explores how expertise shapes human–building interaction during disaster inspections by using eye tracking technology to capture the gaze pattern...Mehr anzeigen

Past research suggests that images can be a useful tool in attracting people’s attention and improving public health communication. This is especially important for the effective transmission of health-related messages to the youth, who should be warned about risks of alcohol and tobacco use. This study explores the application of eye-tracking methodology to investigate the influence of monochromatic illustrations on youths’ visual attention to digital ads, with a particular emphasis on those presenting harmful effects of alcohol and tobacco consumption....Mehr anzeigen

In the vision of Industry 5.0, collaborative robots (or cobots) play a central supporting role in various industries, especially manufacturing. Close interaction with cobots requires special attention to user experience to fully exploit the benefits of this paradigm. Consequently, understanding the impact of a cobot’s physical size on user experience becomes critical to optimizing human–robot collaboration (HRC). This research aims to investigate the relationship between cobot size (UR3e – small cobot vs. UR10e – large cobot) and user experience in HRC c...Mehr anzeigen

Autonomous driving (AD) technology has gradually matured, but the lack of trust and acceptance from users limits its adoption and diffusion. This paper aims to solve the challenges and alleviate the trust crisis by exploring reasonable interactive output modalities. Firstly, we propose a multimodal interactive output scheme with 9 different feedback level. Subsequently, we conduct simulated driving experiments on the scheme, using three methods: driving trust experience questionnaire (DTEQ), eye-tracking, and takeover desire recording. Finally, we analyz...Mehr anzeigen

Virtual reality (VR) technology emerges as a valuable tool for exploring human perception and behavior in controlled, immersive, and risk-free environments. This study applied simulated VR technology to examine the efficacy of preventive visual and auditory warnings for pedestrians at signalized intersections. More specifically, it tested four types of pedestrian signals: conventional signal, laser wall, visual crosswalk, and auditory signal. It explored the influence of these signals on pedestrian behavior under varying environmental and traffic conditi...Mehr anzeigen

Vigilance is the ability to sustain attention. It is crucial in tasks like piloting and driving that involve the ability to sustain attention. However, cognitive performance often falters with prolonged tasks, leading to reduced efficiency, slower reactions, and increased error likelihood. Identifying and addressing diminished vigilance is essential for enhancing driving safety. Neuro-physiological indicators have shown promising results to monitor vigilance, paving the way for neuroadaptive control of vigilance. In fact, the collection of vigilance-rela...Mehr anzeigen
