ObjectiveA respiratory function monitor (RFM) may improve positive pressure ventilation (PPV) technique, but many providers do not use RFM data appropriately during delivery room resuscitation. We sought to use eye-tracking technology to identify RFM parameters that neonatal providers view most commonly during simulated PPV.DesignMixed methods study. Neonatal providers performed RFM-guided PPV on a neonatal manikin while wearing eye-tracking glasses to quantify visual attention on displayed RFM parameters (ie, exhaled tidal volume, flow, leak). Participants subsequently provided qualitative feedback on the eye-tracking glasses.SettingLevel 3 academic neonatal intensive care unit.ParticipantsTwenty neonatal resuscitation providers.Main outcome measuresVisual attention: overall gaze sample percentage; total gaze duration, visit count and average visit duration for each displayed RFM parameter. Qualitative feedback: willingness to wear eye-tracking glasses during clinical resuscitation.ResultsTwenty providers participated in this study. The mean gaze sample captured wa s 93% (SD 4%). Exhaled tidal volume waveform was the RFM parameter with the highest total gaze duration (median 23%, IQR 13–51%), highest visit count (median 5.17 per 10 s, IQR 2.82–6.16) and longest visit duration (median 0.48 s, IQR 0.38–0.81 s). All participants were willing to wear the glasses during clinical resuscitation.ConclusionWearable eye-tracking technology is feasible to identify gaze fixation on the RFM display and is well accepted by providers. Neonatal providers look at exhaled tidal volume more than any other RFM parameter. Future applications of eye-tracking technology include use during clinical resuscitation.

Abstract BACKGROUND Decision-making in neonatal resuscitation depends on clinical evaluation, oxygen saturation and heart-rate. However, the position of vital signs monitors varies between institutions and might lead to obstructed or difficult to see displays, which might affect Health Care Provider (HCP) performance. OBJECTIVES To compare Situation Awareness (SA), Neonatal Resuscitation (NRP) checklist score, Visual Attention (VA) and participant satisfaction during simulated neonatal resuscitations using two vital signs monitors locations. DESIGN/METHODS NRP-trained HCPs were recruited from a tertiary Neonatal Intensive Care Unit and randomized to either central (eye-level on the radiant warmer) or peripheral (left of the warmer) monitor placement. Following an orientation scenario, each HCP lead a resuscitation requiring intubation and chest compressions with a high-fidelity manikin (Newborn HAL, Gaumard Scientific, Miami, FL) and a standardized assistant. Each scenario was paused at 3 predetermined points and the HCP was asked 5 SA questions at each pause, per the Situation Awareness Global Assessment Tool (SAGAT) format. Simulations were video-recorded to analyze SAGAT responses and performance rating using a modified NRP checklist. VA was recorded using eye-tracking glasses (Tobii Pro, Tobii Technology Inc., Falls Church, VA) worn by participants. Statistical analysis was performed using Mann-Whitney U test. A post-simulation survey examined user preference. RESULTS We randomized 30 HCPs; all were analyzed for SA and NRP checklist scores. Twenty-two eye-tracking recordings were of sufficient quality and analyzed. SAGAT scores (median 11/15 vs. 12/15, p=0.52) and NRP Checklist Scores (median 46/50, p=0.75) were similar between groups. Distribution of VA was also similar in both groups. In the post-simulation survey, all HCPs found central monitor placement convenient, compared with only 8/15 in peripheral placement. CONCLUSION During simulated neonatal resuscitation, HCPs found central monitor placement more convenient. However, no differences in accuracy of situation awareness responses, NRP checklist scores, or visual attention were found. Hi-fidelity simulation, SAGAT, and eye-tracking can be used to evaluate physical ergonomics of neonatal resuscitation.

BackgroundA respiratory function monitor (RFM) provides real-time positive pressure ventilation feedback. Whether providers use RFM during neonatal resuscitation is unknown.MethodsAncillary study to the MONITOR(NCT03256578) randomised controlled trial. Neonatal resuscitation leaders at two centres wore eye-tracking glasses, and visual attention (VA) patterns were compared between RFM-visible and RFM-masked groups.Results14 resuscitations (6 RFM-visible, 8 RFM-masked) were analysed. The median total gaze duration on the RFM was significantly higher with a visible RFM (29% vs 1%, p<0.01), while median total gaze duration on other physical objects was significantly lower with a visible RFM (3% vs 8%, p=0.02). Median total gaze duration on the infant was lower with RFM visible, although not statistically significantly (29% vs 46%, p=0.05).ConclusionProviders’ VA patterns differed during neonatal resuscitation when the RFM was visible, emphasising the importance of studying the impact of additional delivery room technology on providers’ behaviour.

Purpose – The purpose of this paper is to elucidate the role that visual measures of attention to product and information and price display signage have on purchase intention. The authors assessed the effect of visual attention to the product, information or price sign on purchase intention, as measured by likelihood to buy. Design/methodology/approach – The authors used eye-tracking technology to collect data from Australian and US garden centre customers, who viewed eight plant displays in which the signs had been altered to show either price or supplemental information (16 images total). The authors compared the role of visual attention to price and information sign, and the role of visual attention to the product when either sign was present on likelihood to buy. Findings – Overall, providing product information on a sign without price elicited higher likelihood to buy than providing a sign with price. The authors found a positive relationship between visual attention to price on the display sign and likelihood to buy, but an inverse relationship between visual attention to information and likelihood to buy. Research limitations/implications – An understanding of the attention-capturing power of merchandise display elements, especially signs, has practical significance. The findings will assist retailers in creating more effective and efficient display signage content, for example, featuring the product information more prominently than the price. The study was conducted on a minimally packaged product, live plants, which may reduce the ability to generalize findings to other product types. Practical implications – The findings will assist retailers in creating more effective and efficient display signage content. The study used only one product category (plants) which may reduce the ability to generalize findings to other product types. Originality/value – The study is one of the first to use eye-tracking in a macro-level, holistic investigation of the attention-capturing value of display signage information and its relationship to likelihood to buy. Researchers, for the first time, now have the ability to empirically test the degree to which attention and decision-making are linked.

Numerous studies have explored the benefit of iconic gestures in speech comprehension. However, only few studies have investigated how visual attention was allocated to these gestures in the context of clear versus degraded speech and the way information is extracted for enhancing comprehension. This study aimed to explore the effect of iconic gestures on comprehension and whether fixating the gesture is required for information extraction. Four types of gestures (i.e., semantically and syntactically incongruent iconic gestures, meaningless configurations, and congruent iconic gestures) were presented in a sentence context in three different listening conditions (i.e., clear, partly degraded or fully degraded speech). Using eye tracking technology, participants’ gaze was recorded, while they watched video clips after which they were invited to answer simple comprehension questions. Results first showed that different types of gestures differently attract attention and that the more speech was degraded, the less participants would pay attention to gestures. Furthermore, semantically incongruent gestures appeared to particularly impair comprehension although not being fixated while congruent gestures appeared to improve comprehension despite also not being fixated. These results suggest that covert attention is sufficient to convey information that will be processed by the listener.

The beautiful, natural environment in a tourist hotel’s marketing images can evoke relaxing and soothing emotions. However, can tourist hotels use nature as a servicescape to make their performing arts services more attractive? Based on attention restoration and servicescape theory, this study explores and compares the influence of tourist hotels’ performing arts images with nature- or built-based servicescapes on the advertising effectiveness (i.e., customer visual attention and behavioral intention). To analyze visual attention on the marketing images, this study uses eye-tracking technology to record customer visual trajectories. This experiment used a total of 113 participants. The sample size of the nature-based servicescape group was 59 (age with mean = 39.04), and that of the built-based servicescape group was 54 (age with mean = 40.17). A tourist hotel’s (Volando Urai Spring Spa & Resort) marketing images were chosen as stimuli. All participants were randomly assigned to the nature-based or the built-based servicescape group. In each experimental group, all the images were randomly presented to reduce any order effects of the images. By using eye-tracking analysis, the experimental findings were as follows: (1) A nature-based servicescape can arouse more visual attention of customers than a built-based servicescape can; (2) Marketing images with performing arts activities in nature-based servicescapes attract the visual attention of customers; (3) Nature-based servicescapes stimulate higher behavioral intentions of consumers than built-based servicescape.

Abstract Background Pediatrics residents are expected to demonstrate preparedness for neonatal resuscitation, yet research has shown gaps in residents' readiness to perform this skill. Objective To evaluate procedural skills and team performance of pediatrics residents during neonatal resuscitation (NR) using a high-fidelity mannequin, and to assess residents' confidence in their NR skills before and after training. Methods Two teams of residents (all had completed NR program training) participated in 2 separate, 90-minute sessions (2 to 3 weeks apart) in an off-site delivery room during their neonatal intensive care rotation. Residents' confidence in assisting and leading NR was surveyed before each session. Teams participated in a scenario (adapted from the NR program), which required 5 skills (positive pressure ventilation, chest compressions, endotracheal intubation, umbilical vein catheterization, and epinephrine administration). Video recording was used for debriefing and scoring. Skills were scored for technique and timeliness, and team behaviors were scored for communication, management, and leadership. Results Twenty-six residents (11 teams) completed 2 paired sessions. Self-confidence scores increased between the 2 sessions but were not correlated with performance. Gaps in procedural skill performance were observed, and timeliness for most skills did not meet expectations. Significant improvement in team communication was noted. Conclusions Important gaps in procedural skill performance, particularly timeliness, were detected by NR simulation training; residents' improvements in self-confidence did not reflect gains in actual performance. Their relative unpreparedness for NR (despite prior certification) highlights the need for deliberate practice and specific team training before and during neonatal intensive care delivery room rotations.

Purpose A striking characteristic of the social communication deficits in individuals with autism is atypical patterns of eye contact during social interactions. We used eye-tracking technology to evaluate how the number of human figures depicted and the presence of sharing activity between the human figures in still photographs influenced visual attention by individuals with autism, typical development, or Down syndrome. We sought to examine visual attention to the contents of visual scene displays, a growing form of augmentative and alternative communication support. Method Eye-tracking technology recorded point-of-gaze while participants viewed 32 photographs in which either 2 or 3 human figures were depicted. Sharing activities between these human figures are either present or absent. The sampling rate was 60 Hz; that is, the technology gathered 60 samples of gaze behavior per second, per participant. Gaze behaviors, including latency to fixate and time spent fixating, were quantified. Results The overall gaze behaviors were quite similar across groups, regardless of the social content depicted. However, individuals with autism were significantly slower than the other groups in latency to first view the human figures, especially when there were 3 people depicted in the photographs (as compared with 2 people). When participants' own viewing pace was considered, individuals with autism resembled those with Down syndrome. Conclusion The current study supports the inclusion of social content with various numbers of human figures and sharing activities between human figures into visual scene displays, regardless of the population served. Study design and reporting practices in eye-tracking literature as it relates to autism and Down syndrome are discussed. Supplemental Material https://doi.org/10.23641/asha.6066545

Objectives: This study aims to investigate patterns of visual attention on a target object in VSDs (Visual Scene Displays) when they are designed with/without an action of usage of the object. We used eye-tracking technology to evaluate how the action of usage of an object in still photographs influenced the visual attention of adults without disabilities. We tried to examine visual attention on the contents of visual scene displays (VSDs).Methods: 25 college students participated in the study. Eye-tracking technology recorded point-of-gaze while participants viewed 20 photographs. Data from eye-tracking provided information on where participants were visually fixated and paid more attention on the presented VSDs including a target object.Results: Both total fixation duration and average fixation count were statistically significant. Participants visually fixated on the target object longer and more often when the object was being used in the presented VSDs. For AOI (Area Of Interest) time of the first fixation, after analyzing only a partial group that had the data match due to the difference in gaze pattern per subject, the average AOI time of the first fixation was shown to be faster when using an object in 6 out of 10 objects.Conclusion: This study supports the inclusion of an action of an object usage in VSDs suggesting that the act of object usage can partially influence the visual attention pattern of a user.

This study was focused on agricultural waste disposal (AWD) textual materials. Two educational texts are compared: designed texts traditionally with no purposeful design and structured knowledge texts, including the textual form of knowledge units. Eye-tracking technology is employed for retrieving the values of critical indicators specifying the way of reading the texts. We analysed users' visual attention and looking behaviour during the reading process. Thirty-three students worked with 45 pieces of educational texts accompanied by a didactic test. Statistical analyses show statistically significant differences neither in any indicator within studying the texts nor in the users' success rate in the didactic test. The users can work with the knowledge structured texts equivalently with the designed texts in the traditional way. The positive effect for AWD is that users can process knowledge structured texts with better results.
