van Zoelen, E.M. (author), van den Bosch, K. (author), Abbink, D. (author), Neerincx, M.A. (author)When humans and AI-agents collaborate, they need to continuously learn about each other and the task. We propose a Team Design Pattern that utilizes adaptivity in the behavior of human and agent team partners, causing new Collaboration Patterns to emerge. Human-AI Co-Learning takes place when partners can formalize recognized patterns of...conference paper 2023

(author)Virtual coaches have the potential to address the low adherence common to eHealth applications for behavior change by, for example, providing motivational support. However, given the multitude of factors affecting users’ attitudes toward virtual coaches, more insights are needed on how such virtual coaches can be designed to affect these...conference paper 2023

Kang, N. (author), Ding, D. (author), van Riemsdijk, M.B. (author), Morina, N. (author), Neerincx, M.A. (author), Brinkman, W.P. (author)Effective psychological interventions for anxiety disorders often include exposure to fearful situations. However, individuals with low self-efficacy may find such exposure too overwhelming. We created a vicarious experience in virtual reality, which enables observation of one’s experience from a first person perspective without actual...article 2021

Numan, N. (author), Haar, F.T. (author), Cesar, P. (author)Head-mounted displays (HMDs) are an essential display device for the observation of virtual reality (VR) environments. However, HMDs obstruct external capturing methods from recording the user’s upper face. This severely impacts social VR applications, such as teleconferencing, which commonly rely on external RGB-D sensors to capture a...conference paper 2021

(author)Drivers struggle to understand how, and when, to safely use their cars' complex automated functions. Training is necessary but costly and time consuming. A Digital In-Car Tutor (DIT) is proposed to support drivers in learning about, and trying out, their car automation during regular drives. During this driving simulator study, we investigated...article 2020

(author), Gelinck, G.H. (author)Ultrasound based mid-air haptic feedback devices can produce tactile sensations at any time and position without restricting human motion. This is useful for augmented and virtual reality, feedback buttons and virtual user interfaces. The haptic feedback mechanism is caused by acoustic radiation force and streaming. Typical solutions to induce...conference paper 2020

Gunkel, S.N.B. (author)Virtual Reality (VR) applications are currently suffering several gaps to allow a full breakthrough in the consumer market. One aspect is the social isolation. Many VR experiences do not represent yourself or other users, making it lonely rather than a shared experience. VR applications that do offer a user representation mostly use artificial...conference paper 2019

(author)In this paper, we describe a user study in which pairs of users watch a video trailer and interact with each other, using two social Virtual Reality (sVR) systems, as well as in a face-to-face condition. The sVR systems are: Facebook Spaces, based on puppet-like customized avatars, and a video-based sVR system using photo-realistic virtual user...conference paper 2019

(author)We propose a real-time change detection system to be used as a vehicle-mounted early-warning system for indicators of improvised explosive devices. Within the context of military route clearance, the system automatically detects suspicious changes in the environment with respect to a previous patrol. For this purpose, historical images of the...article 2019

van der Waa, J.S. (author), van Diggelen, J. (author), Neerincx, M.A. (author)Explainable AI becomes increasingly important as the use of intelligent systems becomes more widespread in high-risk domains. In these domains it is important that the user knows to which degree the system’s decisions can be trusted. To facilitate this, we present the Intuitive Confidence Measure (ICM): A lazy learning meta-model that can...conference paper 2018
