Kim, S. (author), van Egmond, R. (author), Happee, R. (author)In conditionally automated driving (SAE level 3), drivers may take their eyes off the road but will still need to be ready to take control and will, therefore, benefit from information on automation. This study aims to investigate the effectiveness of automation manoeuvre information provided through spatial sound, traditional notification sound...journal article 2024

Zhang, Kaixuan (author), Shi, Zhaochen (author), Zujovic, Jana (author), de Ridder, H. (author), van Egmond, R. (author), Neuhoff, David L. (author), Pappas, T. (author)We present a systematic approach for training and testing structural texture similarity metrics (STSIMs) so that they can be used to exploit texture redundancy for structurally lossless image compression. The training and testing is based on a set of image distortions that reflect the characteristics of the perturbations present in natural...journal article 2024

Bostan, I. (author), van Egmond, R. (author), Gommers, D.A.M.P.J. (author), Ozcan Vieira, E. (author)Intensive Care Unit (ICU) nurses are burdened by excessive number of false and irrelevant alarms generated by patient monitoring systems. Nurses rely on these patient monitoring systems for timely and relevant medical information concerning patients. However, the systems currently in place are not sensitive to the perceptual and cognitive...journal article 2024

Kabbani, T. (author), Kim, S. (author), Serbes, D. (author), Ozan, Berzah (author), van Egmond, R. (author), Hartavi, Ahu Ace (author)Automation of vehicles not only provides greater safety, but also many previously unimagined opportunities, such as less inequality, less stress, and more meaningful activities while driving. However, the uptake and implementation of automated driving have been falling short of its promise, due to challenges in identifying safe and acceptable...journal article 2023

Kim, S. (author), Happee, R. (author), van Egmond, R. (author)The design of take-over requests in automated vehicles traditionally focuses on safety and reaction time. We are interested in how take-over requests can be designed from a broader user experience perspective while ensuring safety. This paper proposes designs for ambient sound (i.e., soundscape) and driving noise to inform the driver of...journal article 2023

Chaves-de-Plaza, Nicolas F. (author), Mody, P. (author), Hildebrandt, K.A. (author), Staring, M. (author), Astreinidou, Eleftheria (author), de Ridder, Mischa (author), de Ridder, H. (author), van Egmond, R. (author)Delineation of tumours and organs-at-risk permits detecting and correcting changes in the patients' anatomy throughout the treatment, making it a core step of adaptive external beam radiotherapy. Although auto-contouring technologies have sped up this process, the time needed to perform the quality assessment of the generated contours remains a...book chapter 2022

Bostan, I. (author), Ozcan Vieira, E. (author), Gommers, Diederik (author), van Egmond, R. (author)Nurses rely on patient monitoring systems for care delivery in ICUs. Monitoring systems communicate information to nurses and alert them through audiovisual alarms. However, excessive numbers of alarms often interrupt nurses in their tasks, and desensitize them to alarms. The affective consequence of this problem is that nurses are annoyed and...conference paper 2022

Kim, S. (author), Kabbani, T. (author), Serbes, D. (author), Happee, R. (author), Hartavi, A. (author), van Egmond, R. (author)Human-Machine Interfaces (HMIs) aim to support the interaction between automated vehicles and drivers to improve safety and driver experience. With the development of automated vehicles, drivers interact with vehicles in new scenarios. In addition to visual modality, sound is the other modality often used in vehicles. Previously, sounds were...conference paper 2022

Mody, Prerak (author), Chaves-de-Plaza, Nicolas F. (author), Hildebrandt, K.A. (author), van Egmond, R. (author), de Ridder, H. (author), Staring, Marius (author)Deep learning models for organ contouring in radiotherapy are poised for clinical usage, but currently, there exist few tools for automated quality assessment (QA) of the predicted contours. Bayesian models and their associated uncertainty, can potentially automate the process of detecting inaccurate predictions. We investigate two Bayesian...journal article 2022

Kim, S. (author), van Egmond, R. (author), Happee, R. (author)In automated driving, the user interface plays an essential role in guiding transitions between automated and manual driving. This literature review identified 25 studies that explicitly studied the effectiveness of user interfaces in automated driving. Our main selection criterion was how the user interface (UI) affected take-over performance...journal article 2021

Dekker, M.C. (author), van Egmond, R. (author), Molenbroek, J.F.M. (author), Vink, P. (author)BACKGROUND: Former studies on work-related upper limb disorders (WRULD) within university education report substantial prevalence rates. In this study, developments in WRULD amongst students in the period 2004-2014 were investigated. Our findings can be a benchmark for future studies, in particular when there are major societal changes as in...journal article 2021

Wang, Jing (author), Zujovic, Jana (author), Choi, June (author), Chakraborty, Basabdutta (author), van Egmond, R. (author), de Ridder, H. (author), Pappas, Thrasyvoulos N. (author)The authors explore the influence of the structure of a texture image on the perception of its color composition through a series of psychophysical studies. They estimate the color composition of a texture by extracting its dominant colors and the associated percentages. They then synthesize new textures with the same color composition but...journal article 2020

Jansen, R.J. (author), van Egmond, R. (author), de Ridder, H. (author)The role of task prioritization in performance tradeoffs during multi-tasking has received widespread attention. However, little is known on whether people have preferences regarding tasks, and if so, whether these preferences conflict with priority instructions. Three experiments were conducted with a high-speed driving game and an auditory...journal article 2016

Brinkman, W.P. (author), Hoekstra, A.R.D. (author), Van Egmond, R. (author)Three studies were conducted to examine the effect of audio on people's experience in a virtual world. The first study showed that people could distinguish between mono, stereo, Dolby surround and 3D audio of a wasp. The second study found significant effects for audio techniques on people's self-reported anxiety, presence, and spatial...conference paper 2015

Ozcan Vieira, E. (author), Van Egmond, R. (author), Jacobs, J.J. (author)In this paper we investigated which categories of product sounds listeners can distinguish. We explored the perceptual domain of product sounds in order to be able to derive perceptually similar categories and determine how users are able to describe these categories by merely listening to them. Employing two different experimental paradigms ...journal article 2014

Jansen, R.J. (author), Van Egmond, R. (author), De Ridder, H. (author), Silvester, S. (author)Operational police work can be characterized by the continuous switching between surveillance, responding to incidents, and office activities. Transitions between these activities are initiated by radio contact, messages on a mobile data terminal, or personal observations. The “information environment” emerging from these channels may cause...conference paper 2013
