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...

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...

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...

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...

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...
