Assessment of Mental Workload by EEG+fNIRS
… have focused on quantitative assessment of mental workload (MWL) in order to enhance the performance, safety, and productivity in working environments. MWL monitoring systems have been used broadly in industry, military, and academia. Moreover, they can be very useful in healthcare as well. …

The Dissociation of Subjective Measures of Mental Workload and Performance
… between performance and subjective measures of workload occurs when two task configurations are compared and the configuration that shows better performance is subjectively perceived as the more difficult task. According to a theory (Wickens & Yeh, 1983), dissociation occurs because subjective …

Exploring mixed reality robot communication under different types of mental workload
… expressions and deployed under various types of mental workload of human teammates. We also present a software architecture that enables mixed reality gestural capabilities, and present the results of a human subject experiment that measures user objective performance and their subjective …

Effects of Increases in Mental Workload on Avoidance of Ground Hazards
… quantities of information and increases in mental workload might cause distraction, reduce attention to dangers in the immediate environment, and threaten soldier survival. The purpose of this laboratory investigation was to quantify the effects of increases in mental workload on one of the …

Improvement of Work Process Performance with Task Assignments and Mental Workload Balancing
… may result in an uneven and ineffective workload distribution among them. Likewise, an even workload distribution without considering the employee's qualifications may cause unproductive employee-task matching that results in low performance of employees. This trade-off is even more …

Using Wireless Dry EEG System to Detect Mental Workload during Mental Arithmetic
Mental workload, the amount of cognitive resources invested during a task, is a crucial metric for performance. Determining the performance of an individual aids in the screening of candidates for, or detection of alertness during, a high-risk task. Three measures for assessing mental workload …

Mental Workload in Personal Information Management: Understanding PIM Practices Across Multiple Devices
… the results of two studies that examined users' mental workload in this context, especially when transitioning tasks from one device to another. In a survey of 220 knowledge workers, users reported high frustration with current devices' support for task migration, e.g. making files available on …

Characterizing Mental Workload in Physical Human-Robot Interaction Using Eye-Tracking Measures
… stem from the need to form accurate internal (mental) models of robot behavior, while also dealing with the intrinsic motor-cognitive demands of physical co-manipulation tasks, and visually monitoring the environment to ensure safe operation. The primary aim of this work was to investigate the …

The Effect of Crosswind and Turbulence in Mental Workload and Pilot Tracking Performance
… the effect of crosswind and turbulence on mental workload and pilot tracking performance. Based on previous research, it was believed that as the amount of crosswind and turbulence is increased, mental workload would increase and tracking performance would decrease. The objective was to …

The impact of rapid transItions in mental workload in a supervisory control setting
… engagement to ones of high stress, high mental workload, and limited time to respond. This research investigates the mental workload transition process from low to high workload by measuring the hemodynamic response of subjects to a simulated missile defense task using functional …

Evaluating Mental Workload for AR Head-Mounted Display Use in Construction Assembly Tasks
… (2) How are moment-to-moment changes of mental workload captured and evaluated during construction assembly tasks? To answer these questions, this dissertation proposed two experiments. The first study tests two AR displays (conformal and tag-along) and paper instruction under complex …

Comparing the Effects of Mental Workload Between Visual and Auditory Secondary Tasks During Laparoscopy
… (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of …

The Effect of Communication Style on Task Performance and Mental Workload Using Wearable Computers
This thesis measured the mental workload associated with operating a voice activated software application run on wearable computer under five different communication styles (buttons, command line, icon buttons, icon text menus, and text menus). The goal of this thesis was to determine which …
