As a result, excessive cognitive workload during an abnormal condition is not an uncommon situation. Almost 70% of accidents in process industries are the result of human error, which is largely modulated by high cognitive workload. A context-dependent methodology using pupillometry was adopted in this study for workload assessment. We found that workload has a significant effect on task performance and subsequent success in handling an abnormal condition. Incorporating contextual information along with pupillometry-based measures was useful to explore the dynamics of variations in workload in depth. In addition, the proposed methodology is a more reliable method for a dynamic environment in which the situation evolves with operator interactions with the process. TECHNICAL ABSTRACT Background Operator workload monitoring has become an important aspect of system engineering due to ever increasing cognitive demands in the control room. Higher cognitive workload, beyond capability, is directly associated with human error in plant operations. Even a small increase in workload during peak demand may result in human error, which can endanger the safety of a process plant. Purpose Subjective methods are of limited use due to the requirement for near real-time evaluation of cognitive workload. Applications such as process plant control room require the operator to reiterate and re-represent the situation based on the contextual cues from environment. Hence, our objective was to develop and test a methodology that incorporates contextual information in workload measurement using pupillometry. Method Participants (n = 44) performed simulated process control tasks. Pupil size was recorded using an eye-tracking device. Recorded pupil size was analyzed based on a methodology that incorporates contextual information from the human-machine interface. Events that present new information about the current state of the process were categorized as critical events. Pupil size variation was adopted to provide an estimate of cognitive workload between consecutive critical events. Results Cognitive workload was associated with process behavior and operator actions. An increase in cognitive workload for specific events was observed when participant actions deteriorated process conditions. We also observed that overall task performance was associated with the frequency of certain events and corresponding variations in pupillary behavior. Conclusion Incorporating contextual information provides more detailed insights into the dynamics of variations in cognitive workload. The mental representation of a current situation may vary depending on expertise level.

This study guides occupational health workers by identifying the potential gains (reduced perceived time demand, number of gestures and number of errors) and concerns (the cobot takes a long time to perceive its environment, which leads to an increased completion time) associated with working with cobots. In our study, the collaboration between human and cobot during an assembly task did not negatively impact perceived cognitive load, increased completion time (but decreased perceived time demand), and decreased the number of gestures performed by participants and the number of errors made. Thus, performing the task in collaboration with a cobot improved the user’s experience and performance, except for completion time, which increased. This study opens avenues to investigate how to improve cobots to ensure the usability of the human-machine system at work. TECHNICAL ABSTRACT Background Industry 4.0 implements smart technologies to increase productivity and to decrease the associated risks. Using cobots is considered by industry as a potential means to reduce physical constraints and improve performance without having to replace the human factor. Research has yet to prove these benefits on humans. Purpose The goal of this study was to determine if working with a cobot improved perceived cognitive load of an operator and the usability of the system. Methods Participants replicated three construction models using Duplos. Approximatively half of our participants (n = 32) accomplished the task alone and the other half accomplished the same task with a cobot (n = 22). We then used the NASA-TLX to measure workload and, through a sub-dimension, perceived cognitive load. Completion time (for each model), number of errors (placing and replacing a piece), and the number of gestures (movements of the upper limbs) were also measured. Results Collaboration with a cobot led to significantly fewer gestures (51 vs. 74), fewer errors (2 vs. 8), and reduced perceived time demand but increased completion time (136 vs. 55 s). Perceived cognitive load was not impacted by the cobot (36 vs. 37). Conclusion We conclude that collaboration with a cobot adapting to human variability is possible, and that it could lead to better performance and could improve certain dimensions of system usability.","PeriodicalId":73332,"journal":{"name":"IISE transactions on occupational ergonomics and human factors","volume":"10 1","pages":"83 - 90"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49644514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also evident were that the major factors contributing to EXO-use-intention are perceived comfort, task-technology fit, perceived safety, and perceived usefulness. A user’s perception of perceived usability may be established by using an exoskeleton during actual job tasks, yet some aspects of perceived usability likely require multiple exposures to an EXO for an accurate assessment. Many negative comments regarding EXO use were related to physical constraints (e.g., restricted movements, bulkiness), and to the EXO interface (e.g., straps, cuff designs), suggesting a need for further research on EXO design to minimize discomfort. In practice, there is likely value in having workers use and explore candidate EXOs during their actual job, both to accurately assess the usefulness of an EXO and to find the most effective EXO. TECHNICAL ABSTRACT Background There lacks an understanding of using an exoskeleton (EXO) in diverse manufacturing environments. Purpose Goals of this study were to: (1) gather worker feedback on different EXOs after using them during their actual jobs; (2) understand what contributes to EXO-use-intention in manufacturing companies; and (3) develop a decision tree model to explore which task characteristics and user perceptions might aid in determining how to implement an EXO effectively. Methods A field study was completed in five manufacturing companies in the state of Ohio. Fifteen participants used preferred EXOs selected from among two arm-support and two back-support devices during their regular jobs for ≤30 minutes in each of two separate sessions. After using an EXO, participants completed a questionnaire addressing several aspects of usability, comfort, safety, and EXO-use-intention. Open-ended comments on these aspects were coded into emerging themes. A decision tree analysis was performed on participants’ responses to the EXO-use-intention question to explore the predictive value of task characteristics, user characteristics, and questionnaire responses. Results Responses to usability-related questions were rather consistent between the two sessions, yet some responses were more positive in the 2nd session (perceived balance, overall comfort and fit, and range-of-motion). We identified four themes regarding EXO use—utility for work, wearability, working metrics, and ease of using; and negative comments on these themes were largely related to physical constraints from wearing an EXO, and EXO interface.
