Relationship Between Quiet Eye and Kinematic Characteristics Based on Expertise in Badminton Backhand Serve

The badminton backhand serve is a fundamental skill that determines the start of a rally, requiring precise timing and stable movement control. In particular, effective visual attention, known as Quiet Eye (QE), is likely to play a crucial role in movement planning and motor control. However, research on QE during the execution of a badminton backhand serve remains limited. Therefore, this study aims to examine the differences in QE based on expertise while analyzing the interaction between QE and upper limb joint movements to understand the underlying mechanisms of the execution of the serve. By doing so, this study seeks to identify the specific visual information involved in badminton backhand serve performance and provide foundational data for performance enhancement. Expert and novice players were instructed to perform backhand short and long serves in both singles and doubles conditions, and QE, wrist joint MEA (Maximum Extension Angular Velocity), and elbow joint MEA were analyzed for each condition. The results showed that skilled players had a longer QE duration than novices, with a particularly longer QE and lower wrist MEA observed in the doubles short serve condition. Additionally, a significant correlation between QE and MEA was found during the execution of the short serve. These findings align with certain aspects of the posture-kinematics hypothesis, particularly in terms of joint-level control. However, further research incorporating direct measures of postural control is required, and there is a need for a more refined analysis of the relationship between visual attention and motor control in badminton serves.

Road Signs Perception: Eye Tracking Case Study in Real Road Traffic

This study investigates driver visual perception of road traffic signs under real road conditions. Using mobile eye tracking technology, we analyzed glance behavior toward various traffic signs and advertisements along urban and highway routes during daytime and nighttime conditions. Results showed significant differences in glance duration and frequency based on sign type, environmental conditions, and the presence of advertisements. Drivers primarily focused on speed limit and directional signs, while advertisements attracted longer glance durations despite their lower frequency of detection. Nighttime conditions generally led to increased glance durations and higher frequencies for most traffic sign types. These findings highlight the importance of optimizing road signage design and placement to improve driver attention and road safety, especially in environments with high visual clutter. Limitations include the exclusion of peripheral vision effects and potential biases introduced by experimental settings.

Role of Eye-Tracking Technology and Software Algorithms in Enhancing ADHD Detection and Diagnosis: A Systematic Literature Review

This systematic literature review explores the role of eye-tracking technology and software algorithms in enhancing the detection and diagnosis of ADHD. ADHD, a neurodevelopmental disorder affecting both children and adults, is traditionally diagnosed through behavioral assessments, which may lack objectivity. Recent studies suggest that eye-tracking, specifically focusing on saccades, fixations, and blink rates, offers the potential for more accurate and objective measures of ADHD. The review examines clinical trials, observational studies, and machine learning research to assess the correlation between ADHD and eye movement patterns. Results indicate that individuals with ADHD exhibit distinct eye movement patterns, which can be quantified through eye-tracking technology and analyzed using software algorithms. These technologies have shown promise in improving diagnostic accuracy, with machine learning models further enhancing their potential. However, the effectiveness of these interventions varies across age groups and study designs, highlighting the need for further research to refine these tools for clinical application. Eye-tracking technology and assessment software provide a valuable supplement to traditional diagnostic methods but require further validation and standardization before widespread clinical use in children and adults.

Speech planning depends on next-speaker selection: evidence from pupillometry in question–answer sequences in naturalistic triadic conversation

Next-speaker selection, which controls who should speak next, is fundamental to turn taking. While it is central in Conversation Analysis, little is known about its cognitive repercussions. We draw on turn-taking and pupillometric data in triadic interaction, investigating open-floor questions, which license more than one participant to respond, and closed-floor questions, which license only a single participant to answer. Comparing pupil size changes in answerers versus not- answerers at turn transitions, we find that answerers’ pupils dilate irrespective of question type, while not-answerers’ pupils dilate only in open-floor questions, indicating that in closed-floor questions not-selected participants do not prepare a response, whereas in open-floor questions both recipients engage in response planning, even if only one responds. Mutual gaze, by contrast, is not found to have an effect on pupil size at turn transitions. We propose an extension to the current model of language processing in turn taking, including next-speaker selection as a relevant variable impacting interlocutors’ behavior and their mental processes.

Study on the Influence of Rural Highway Landscape Green Vision Rate on Driving Load Based on Factor Analysis

Year: 2025 | Published by: School of Civil Engineering Architecture and the Environment, Hubei University of Technology, Wuhan 430068, China , Key Laboratory of Intelligent Health Perception and Ecological Restoration of Rivers and Lakes, Ministry of Education, Hubei University of Technology, Wuhan 430068, China

Authors: Hao Li, Jiabao Yang, Heng Jiang

The green vision rate of rural highway greening landscape is a key factor affecting the driver’s visual load. Based on this, this paper uses the eye tracking method to study the visual characteristics of drivers in different green vision environments on rural highways in Xianning County. Based on the HSV color space model, this paper obtains four sections of rural highway with a green vision rate of 10~20%, green vision rate of 20~30%, green vision rate of 30~40%, and green vision rate of 40~50%. Through the real car test, the pupil area, fixation time, saccade time, saccade angle, saccade speed, and other visual indicators of the driver’s green vision rate in each section were obtained. The visual load quantization model was combined with factor analysis to explore the influence degree of the green vision rate in each section on the driver’s visual load. The results show that the visual load of the driver in the four segments with different green vision rate is as follows: Z10~20% > Z20~30% > Z30~40% > Z40~50%. When the green vision rate is 10~20%, the driver’s fixation time becomes longer, the pupil area becomes larger, the visual load is the highest, and the driving is unstable. When the green vision rate is 40% to 50%, the driver’s fixation time and pupil area reach the minimum, the visual load is the lowest, and the driving stability is the highest. The research results can provide theoretical support for the design of rural highway landscape green vision rate and help to promote the theoretical research of traffic safety.

Study the nighttime visual attention in urban waterfront public space: Insights using mobile eye-tracking

The study aims to explore people's nighttime visual attention in urban waterfront public space during leisure activities, and analyze the impact of artificial lighting on visual attention. The study first utilized mobile eye-tracker to collect participants' eye-movement data in typical urban waterfront leisure routes, along with corresponding artificial lighting data. Next, based on the collected data, visual attention statistical datasets composed of two dependent variable indicators, visual attention distribution ratio and average attention fixation duration, were constructed. Then, impact analyses of artificial lighting on these indicators were conducted by controlling age groups and environment elements. Results show: 1) opposite scenery, greenery, recreation and sport facilities are the most visually attractive elements; 2) significant differences in visual attention preferences across three age groups were found on opposite scenery, ground, landscape structures, people, etc.; 3) nighttime visual attention induced by 11 types of environment elements is significantly impacted by artificial lighting. The maximum R2 of vertical illuminance on visual attention can reach up to 0.603, while 0.472 for horizontal illuminance and 0.247 for correlated color temperature. Additionally, artificial lighting has the greatest impact on the elderly's visual attention. The results help to provide refined human-centered perception insights for improving nighttime environment quality.

The aesthetic nature of Chinese-inscribed poetry and painting texts—evidence from eye movements

Previous studies on traditional Chinese inscribed poems and paintings have primarily been subjective qualitative analyses conducted by researchers. In this study, eye-tracking techniques and equipment were utilized to objectively analyze hotspot maps, Area of Interest (AOI) first gaze duration, AOI gaze duration, and sight-switching frequency of viewers when observing inscribed poems and paintings. This research presents these analyses impartially in the form of quantitative data. It reports the eye-tracking data and aesthetic tendencies of three groups with varying art education backgrounds when viewing inscribed poetic paintings. The experiments demonstrated statistically significant differences in aesthetic appreciation, revealing that the inscribed poems and paintings significantly influence the aesthetics of individuals with different art education backgrounds. In the group with the original inscribed poems and paintings, significant differences were observed in the eye-tracking data across the three groups with varying art education backgrounds. Participants with professional art backgrounds focused more on the interaction between the poetry text and the painting. In contrast, in the text + audio narration group, the eye-tracking data of all three groups overlapped significantly, suggesting that understanding the meaning of the poetic text enhanced aesthetic appreciation, particularly for those without professional art backgrounds. Our findings provide insights into the aesthetic appreciation of traditional Chinese paintings, audience perceptions and understandings of artworks, and art museum display practices.

The Change of Gaze Behavior, Eye-Head Coordination, and Temporal Characteristics of Swing by Task Constraints in Tennis Volley Strokes.

The purpose of this study was to determine how gaze behavior and eye-head coordination were farmed to acquire visual information for successful performance, and to examine the relationship between gaze behavior and temporal characteristics of swing in the tennis volley stroke. Eight elite players were required to do a volley stroke to one of two target areas in four conditions (pre-cue and forehand only, pre-cue and fore/backhand combination, post-cue and forehand only, and post-cue and fore/backhand combination). The data on gaze behavior and temporal characteristics of the swing were collected using both VIA system and motion analysis system. A laser sensor was used to manipulate the cue light time for target presentation. Results showed that gaze behavior was affected by the manipulation of cue condition. Participants used an earlier first gaze shift, earlier quiet eye onset, longer quiet eye duration and longer eye-head stabilization duration in pre-cue condition than in post-cue condition. However, there were no significant effects of the manipulation of the volley stroke direction on gaze behavior. Gaze behavior was also affected by shot accuracy, with an earlier first gaze shift, earlier quiet eye onset, longer quiet eye duration and longer eye-head stabilization duration during hits than misses. During the backswing, participants used an earlier initiation and slower swing in pre-cue condition and forehand only condition, and during hits. But there were no significant effects of both manipulation of task constraints and shot accuracy on temporal characteristics of the forward swing. Lastly, the initiation time and movement time of backswing had a higher relation to gaze behavior, such as the first shift of gaze, quiet eye onset and quiet eye duration, during hits than misses. But there was no significant correlation between gaze behavior and temporal characteristics of forward swing during hits.
