An Investigation Of The Relationship Between Subjective Mental Workload And Objective Indicators Of User Activity, Greg Byrne
Dissertations
Whilst the concept of physical workload is intuitively understood and readily applicable in system design, the same cannot be said of mental workload (MWL), despite its importance in our increasingly technological society. Despite its origin in the mid 20th century, the very concept of ”mental workload” is still a topic of debate in the literature, although it can be loosely defined as “the amount of mental work necessary for a person to complete a task” (Miller, 1956; Longo, 2014). Several methods have been utilized to measure of MWL, including physiological methods such as neuro-imagery, performance-based metrics, and subjective measures via …

Discover Influential Mental Workload Attributes Impacting Learners Performance In Third-Level Education, Amisha Mehta
Discover Influential Mental Workload Attributes Impacting Learners Performance In Third-Level Education, Amisha Mehta
Dissertations
Human Mental Workload is an intervening variable and a fundamental concept in the discipline of Ergonomics. It is deduced from variations in performance. High or low mental workload leads to hampering of performance. Mental workload in an educational setting has been extensively researched. It is applied in instructional design but it is obscure as to which factors are majorly driving mental workload in learners. This dissertation investigates the importance of the features used in the the NASA-Task Load Index mental workload assessment instrument and their impact on the performance of learners as assessed by multiple-choice tests conducted in classrooms of …
An Application Of Natural Language Processing For Triangulation Of Cognitive Load Assessments In Third Level Education, Luis Alfredo Contreras
An Application Of Natural Language Processing For Triangulation Of Cognitive Load Assessments In Third Level Education, Luis Alfredo Contreras
Dissertations
Work has been done to measure Mental Workload based on applications mainly related to ergonomics, human factors, and Machine Learning. The influence of Machine Learning is a reflection of an increased use of new technologies applied to areas conventionally dominated by theoretical approaches. However, collaboration between MWL and Natural Language Processing techniques seems to happen rarely. In this sense, the objective of this research is to make use of Natural Languages Processing techniques to contribute to the analysis of the relationship between Mental Workload subjective measures and Relative Frequency Ratios of keywords gathered during pre-tasks and post-tasks of MWL activities …
An Investigation Of The Correlation Between Mental Workload And Web User’S Interaction, Joaquim Filipe Romero
An Investigation Of The Correlation Between Mental Workload And Web User’S Interaction, Joaquim Filipe Romero
Dissertations
Mental Workload, a psychological concept, was identified as being linked with task’s and system’s performance. In the context of Human-Computer Interaction, recent research has identified Mental Workload as an important measure in the designing and evaluation of web interfaces, and as an additional and supplemental insight to typical usability evaluation methods. Simultaneously, web logs containing data related to web users’ interaction (e.g. scrolling; mouse clicks) have been proved useful in evaluating the usability of web sites by analysing the data tracked for hundreds of users. In order to study if the potential of logs of user interaction can be applied …
Evaluating The Effectiveness Of The Gestalt Principles Of Perceptual Observation For Virtual Reality User Interface Design, William Macnamara
Evaluating The Effectiveness Of The Gestalt Principles Of Perceptual Observation For Virtual Reality User Interface Design, William Macnamara
Dissertations
There is a lot of interest and excitement surrounding the areas of Virtual Reality and Head-Mounted Displays with the recent releases of devices such as the Oculus Rift, Sony PSVR and the HTC Vive. While much of the focus for these devices has been related to sectors of the entertainment industries, namely the cinema and video game industries, there are many more practical applications for these technologies, with potential benefits in educational, training/simulation, therapeutic and modelling/design software. Developing a set of reliable guidelines for Virtual Reality User Interface Design could play a crucial role in whether the medium successfully integrates …
