Investigating the modeling assumptions of alert-driven attack graphs: A cognitive load-based quantification approach of interpretability in attack graphs

The interpretability of an attack graph is a key principle as it reflects the difficulty of a specialist to take insights into attacker strategies. However, the quantification of interpretability is considered to be a subjective manner and complex attack graphs can be challenging to read and interpret. In this research paper, we propose a new...

The effect of cognitive load on the effect of external Human-Machine Interfaces: An eye-tracker experiment

With the increase in development of self-driving cars, research has been conducted to retain humanized interaction between cars and other road users, such as pedestrians. One way to retain this type of interaction is through the use of external Human-Machine Interfaces (eHMIs). This project aims to contribute to this field of research by...

Improving distance learning with holograms

Previous studies have found that there is a strong correlation between the social presence of a teacher and perceived performance of students, and that an increased cognitive load decreases the effectiveness in problem solving. The objective of this study was to find out to what extend holograms can be used to improve the social presence of the...

Naturalistic visualization of reaching movements using head-mounted displays improves movement quality compared to conventional computer screens and proves high usability

Background: The relearning of movements after brain injury can be optimized by providing intensive, meaningful, and motivating training using virtual reality (VR). However, most current solutions use two-dimensional (2D) screens, where patients interact via symbolic representations of their limbs (e.g., a cursor). These 2D screens lack depth...

Measuring Cognitive Load: Are There More Valid Alternatives to Likert Rating Scales?

Cognitive load researchers have used varying subjective techniques based on rating scales to quantify experienced cognitive load. Although it is generally assumed that subjects can introspect on their cognitive processes and have no difficulty in assigning numerical values to the imposed cognitive load, little is known about how visual...

Is accommodation a confounder in pupillometry research?

Much psychological research uses pupil diameter measurements to investigate the cognitive and emotional effects of visual stimuli. A potential problem is that accommodating at a nearby point causes the pupil to constrict. This study examined to what extent accommodation is a confounder in pupillometry research. Participants solved...

Effect of immersive visualization technologies on cognitive load, motivation, usability, and embodiment

Virtual reality (VR) is a promising tool to promote motor (re)learning in healthy users and brain-injured patients. However, in current VR-based motor training, movements of the users performed in a three-dimensional space are usually visualized on computer screens, televisions, or projection systems, which lack depth cues (2D screen), and...

Understanding the Potential of Augmented Reality in Manufacturing Environments

Manufacturing companies are confronted with challenges due to increasing flexibility requirements and skill gaps. Augmented Reality applications offer an efficient way to overcome these tensions by enhancing the interaction between people and technology. The positive effects of Augmented Reality solutions are often described in individual models...

Effects of personal characteristics in control-oriented user interfaces for music recommender systems

Music recommender systems typically offer a “one-size-fits-all” approach with the same user controls and visualizations for all users. However, the effectiveness of interactive interfaces for music recommender systems is likely to be affected by individual differences. In this paper, we first conduct a comprehensive literature review of...

Effects of Personal Characteristics on Music Recommender Systems with Different Levels of Controllability

Previous research has found that enabling users to control the recommendation process increases user satisfaction. However, providing additional controls also increases cognitive load, and different users have different needs for control. Therefore, in this study, we investigate the effect of two personal characteristics: musical sophistication...

KLM Customer Journey: Baggage

The research examines the interactions and experiences of airline passengers during baggage reclaim with the goal of understanding their motives, what factors influence their experiences and decisions, and what struggles and stresses they encounter during the reclaim process. Interviews and Journey Mapping are leveraged to gain insights and...

Workload assessment for mental arithmetic tasks using the task-evoked pupillary response

Pupillometry is a promising method for assessing mental workload and could<br/>be helpful in the optimization of systems that involve human–computer<br/>interaction. The present study focuses on replicating the studies by Ahern<br/>(1978) and Klingner (2010), which found that for three levels of difficulty<br/>of mental multiplications, the more...

A training approach for the transition of repeatable collaboration processes to practitioners

This paper presents a training approach to support the deployment of collaboration process support according to the Collaboration Engineering approach. In Collaboration Engineering, practitioners in an organization are trained to facilitate a specific collaborative work practice on a recurring basis. To transfer the complex skill set of a...

Cognitive load measurements and stimulated recall interviews for studying the effects of information and communications technology

Many researchers use information and communications technology (ICT)-tools to augment learning in a great variety of tasks. Their effects are generally measured in terms of intended outcomes. This article argues for the use of additional, more general measures to obtain a more complete impression of the effects of ICT-tools. The first study...
