“…Since these systems provide additional functions beneficial for road safety (e.g., increased field of view, monitors positioned closer to the driver’s eye point, image augmentation), the increased acceptance could increase road safety indirectly. Positive effects of a higher perspective on orientation and localization have been observed in visual-motor tasks (Lodinger & DeLucia, 2019; Ustinova et al, 2010) and indirect viewing systems (Bao et al, 2013; van Erp & Padmos, 2003). Moreover, Viputsakul et al (2020) observed improved localization performance with a digital bird’s-eye view mirror.…”

Objective This experiment provides a first-of-its-kind driving-simulator study to investigate the feasibility of camera-monitor systems (CMS) with displaced side-mounted cameras in sedans. Background Among the increasing number of studies investigating the replacement of side-mounted rearview mirrors with CMS, the placement of side-mounted cameras has been largely neglected. Moreover, user preferences with respect to camera placement have not been validated in a driving simulator. Past research merely has shown that the vertical camera position can affect distance perception. Method In a driving simulator experiment, we investigated the effects of rearward camera placement on driver acceptance and performance. Thirty-six participants performed multiple lane changes in a last safe-gap paradigm. The camera position, ego-velocity, and velocity of the approaching vehicle varied across the experiment. Results The results suggest a clear preference for a high rearward perspective, whereas participants disliked the lower viewpoint. However, these stark differences were only marginally mirrored in lane change performance. Average safety margins tended to decrease and their variation tended to increase for the low camera position. Conclusion Even if the impact of the camera position on driving behavior seems to be small in sedans, driver expectations show clear-cut preferences. When designing CMS, this should be taken into account, as these preferences could promote the use of CMS and thus their positive impact on safety. Application Designers should place side-mounted cameras as high as possible to increase acceptance of CMS. Low camera positions are not recommended, as they might decrease safety margins and are not appreciated by drivers.

Worker safety and productivity are crucial for effective job management. Interruptions to an individual's work environment and their impact on mental health can have adverse effects. One prospective instrument for assessing and calculating an individual's mental state in an interrupted scenario and cognitive demand levels is the use of physiological computing devices in conjunction with behavioral and subjective measurements. This study sought to address how to gather and compute data on individuals' cognitive states in interrupted work settings through critical analysis. Thirty-three papers were considered after the literature search and selection procedure. This descriptive study is conducted from three perspectives: parameter measurement, research design, and data analysis. The variables evaluated were working memory, stress, emotional state, performance, and resumption lag. The subject recruitment, experimental task design, and measurement techniques were examined from the standpoint of the experimental design. Data analysis included computing and cognitive pre-processing. Four future research directions are suggested to address the shortcomings of the present studies. This study offers suggestions for researchers on experiment planning and using computing to analyze individuals' cognitive states during interrupted work scenarios. Additionally, it offers helpful recommendations for organizing and conducting future research.

Angle of Camera View Influences Resumption Lag in a Visual-Motor Task

Abstract: Training for laparoscopic surgery should include interruptions to allow surgeons to practice resuming a surgery-related task after an interruption and consequently shorten the time needed to resume the surgery-related task.
