Head pose has been proposed as a surrogate for eye movement to predict areas of interest (AOIs) where drivers allocate their attention. However, head pose may disassociate with AOIs in glance behavior involving zero or subtle head movements, commonly known as “lizard” glance pattern. In contrast, “owl” glance pattern is used to describe glance behavior along with larger head movements. It remains unclear which glance pattern is prevalent during driver cell phone distraction and what are appropriate metrics to detect such distraction. To address this gap, we analyzed the gaze direction and head pose of 36 participants who completed an email-sorting task using a cell phone while driving a Tesla on the test track in Autopilot mode. The dispersion-threshold algorithm identified driver gaze fixations and synchronized them with head movements. The results showed that when using a cell phone either near the lap or behind the steering wheel, participants exhibited a dominant lizard-type glance pattern with minimal shift in head position. As a result, head pose alone may not provide sufficient information for cell phone distraction detection, and gaze metrics should be involved in enhancing this application.

Objective The study aimed to analyze the gaze fixation of pediatricians during the decision process regarding the presence/absence of pain in pictures of newborn infants. Study Design Experimental study, involving 38 pediatricians (92% females, 34.6 ± 9.0 years, 22 neonatologists) who evaluated 20 pictures (two pictures of each newborn: one at rest and one during a painful procedure), presented in random order for each participant. The Tobii-TX300 equipment tracked eye movements in four areas of interest of each picture (AOI): mouth, eyes, forehead, and nasolabial furrow. Pediatricians evaluated the intensity of pain with a verbal analogue score from 0 to 10 (0 = no pain; 10 = maximum pain). The number of pictures in which pediatricians fixed their gaze, the number of gaze fixations, and the total and average time of gaze fixations were compared among the AOI by analysis of variance (ANOVA). The visual-tracking parameters of the pictures' evaluations were also compared by ANOVA according to the pediatricians' perception of pain presence: moderate/severe (score = 6–10), mild (score = 3–5), and absent (score = 0–2). The association between the total time of gaze fixations in the AOI and pain perception was assessed by logistic regression. Results In the 20 newborn pictures, the mean number of gaze fixations was greater in the mouth, eyes, and forehead than in the nasolabial furrow. Also, the average total time of gaze fixations was greater in the mouth and forehead than in the nasolabial furrow. Controlling for the time of gaze fixation in the AOI, each additional second in the time of gaze fixation in the mouth (odds ratio [OR]: 1.26; 95% confidence interval [CI]: 1.08–1.46) and forehead (OR: 1.16; 95% CI: 1.02–1.33) was associated with an increase in the chance of moderate/severe pain presence in the neonatal facial picture. Conclusion When challenged to say whether pain is present in pictures of newborn infants' faces, pediatricians fix their gaze preferably in the mouth. The longer duration of gaze fixation in the mouth and forehead is associated with an increase perception that moderate/severe pain is present. Key Points

Development Of Language

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.

Simulated Driving Task

This study used both cellular phones and analogue radio to measure driver distraction and workload in a low fidelity driving simulator. Thirty-four participants performed a simulated driving task while using either a cell phone or a radio in conjunction with a secondary task assessing their spare attentional capacity. The results showed that more lane deviations were made during the cell phone and radio tuning use than both of the pre-allocation and Post-allocation phases. The secondary task errors were also higher during both the cell phone and radio tuning allocation phase than the pre-allocation and post-allocation phases. These findings indicate the greater workload load levels associated with the use of telemetric devices. These findings have major implications for driver safety and telemetric systems design.

Purpose The purpose of this study is to explore the characteristics and potential effects of teaching and learning through audio teleconferencing (dial-in) with a cell phone. In addition, the study aims to identify the associations between the audio teleconferencing and video teleconferencing in a 12-week postgraduate course. Design/methodology/approach The study is a cross-sectional survey conducted at the Department of Educational Innovations at the Kwame Nkrumah University of Science and Technology from March to June 2020. The purposive sampling technique was used to sample 100 postgraduate students who registered for a course in the department. The data for the study were collected using the System Usability Scale (SUS) and 17-item self-administered eQuestionnaire. Multiple Linear Regression analysis, ANOVA, Independent sample T-test and Mann–Whitney U-test were used to estimate the differences in course achievements of students who experienced education through audio teleconferencing and those who experienced education through video teleconferencing. Findings In total, 59% of the participating postgraduate students chose to attend the synchronous online lectures via audio teleconferencing (dial-in). The participants gave a high SUS score (SUS > 80.3; Grade A; Excellent) for audio conferencing service. Among the students in the audio teleconferencing cohort, the results evidenced a strong positive linear correlation, (r (57) = 0.79, p < 0.05), between the individual adjective ratings and the SUS scores. There was marginal significance among demography of students in the audio teleconference (AT) cohort with regards to their perception about the dial-in lecture. There was no statistically significant difference, (t (98) = 1.88, p = 0.063), in the achievement test for AT students and video teleconference (VT) students. The instructors and the students were satisfied with the AT. Practical implications Based on the students’ preference, AT offers equal benefit as VT with regards to system satisfaction and perceived quality of online teaching. AT, as teaching modality, should be an option for students who reside in communities with high latency internet connectivity. It is recommended that instructors are trained on how to engage and motivate students via AT. Originality/value Higher education institutions in Ghana are facing decisions about how to continue learning and teaching through flexible pedagogy, while keeping their faculty members and students protected from the COVID-19 pandemic. Many of these institutions have canceled the brick-and-mortar education and other conventional learning practices and have instructed faculty to adopt online teaching through synchronous video teleconferencing platforms. However, the learning experience is not the same for students who reside in remote or rural communities with low bandwidth. There is very little research in this topic, especially in developing countries like Ghana, and the present study aims to bridge the gap in the literature by exploring the characteristics and potential effects of teaching and learning through audio teleconferencing (dial-in) with a cell phone, in the context of a 12-week postgraduate course.

BACKGROUND The coronavirus disease 2019 (COVID-19) heralded an unprecedented increase in telemedicine utilization. OBJECTIVE Assess patient satisfaction with telemedicine during COVID-19 METHODS Telemedicine visit data were gathered from two separate institutions (Stanford Health Care (Stanford) and the Hospital for Special Surgery (HSS)). Patient satisfaction data from HSS were captured from a Press-Ganey questionnaire between April 19, 2020 and December 12, 2020, while the Stanford data was taken from a novel survey instrument that was distributed to all patients between June 22, 2020 and November 1, 2020. There were 60,550 telemedicine visits across 93 services at Stanford, each linked with a post-visit survey. At HSS, there were 66,349 total telemedicine visits with 7,348 randomly linked with a post-visit survey. The percentage of respondents who reported the highest possible likelihood to recommend score (“LTR top box percentage”) and mean overall visit scores were recorded. RESULTS Over 19 weeks, the LTR top box percentage at Stanford increased from 69.6% to 74.0% (p=.0002), and HSS showed no significant change across 35 weeks (p=.7100). LTR trend stability at Stanford was observed across 11 medical, four surgical, and five oncological services (p >.05). In the multivariable model, the use of a cell phone (aOR: 1.18; 95% CI: 1.12–1.23) and tablet (aOR: 1.15; 95% CI: 1.07–1.23) were associated with higher overall scores, while visits with interrupted connections (aOR: 0.49; 95% CI: 0.42–0.57) or help required to connect (aOR: 0.49; 95% CI: 0.42–0.56) predicted lower patient satisfaction. CONCLUSIONS We present the largest published description of patient satisfaction with telemedicine. We found high satisfaction with telemedicine encounters across multiple measures, and we identified a number of important telemedicine-specific factors that predict increased overall visit score. These include the use of cell phones or tablets, phone reminders, and connecting before the visit was scheduled to begin. Visits with poor connectivity, extended wait times, or difficulty being seen, examined, or understood by the provider were linked with reduced odds of high scores. Our results suggest that attention to connectivity and audio/visual definition will help optimize patient satisfaction with telemedicine encounters in the future. CLINICALTRIAL n/a
