Evaluating the Vergence-Accommodation Conflict in Gaze-Based 3D Target Selection
Mohammad Raihanul Bashar, Mohammadreza Amini, Aunnoy K Mutasim +3
State-of-the-art head-mounted displays (HMDs) enable gaze-based selection in virtual environments. Yet, these HMDs suffer from the vergence-accommodation conflict (VAC), which is k…
Play and Learn: Gamified Feedback for Ultrasound-Guided Catheter Insertion Training in Virtual Reality
Mohammad Raihanul Bashar, Alejandro Olivares Hernandez, Yahia Zine +1
VR is widely used in procedural medical training, but many simulators prioritize realism over formative feedback. We developed a gamified VR simulator for ultrasound-guided periphe…
Eyes on Many: Evaluating Gaze, Hand, and Voice for Multi-Object Selection in Extended Reality
Mohammad Raihanul Bashar, Aunnoy K Mutasim, Ken Pfeuffer +1
Interacting with multiple objects simultaneously makes us fast. A pre-step to this interaction is to select the objects, i.e., multi-object selection, which is enabled through two…
Varifocal Displays Reduce the Impact of the Vergence-Accommodation Conflict on 3D Pointing Performance in Augmented Reality Systems
Xiaodan Hu, Monica Perusquía-Hernández, Mayra Donaji Barrera Machuca +4
This paper investigates whether a custom varifocal display can improve 3D pointing performance in augmented reality (AR), where the vergence-accommodation conflict (VAC) is known t…
Shades of Uncertainty: How AI Uncertainty Visualizations Affect Trust in Alzheimer's Predictions
Jonatan Reyes, Mina Massoumi, Anil Ufuk Batmaz +1
Artificial intelligence (AI) is increasingly used to support prognosis in Alzheimer's disease (AD), but adoption remains limited due to a lack of transparency and interpretability,…
Ping! Your Food is Ready: Comparing Different Notification Techniques in 3D AR Cooking Environment
Aditya Raikwar, Lucas Plabst, Anil Ufuk Batmaz +2
Implementing visual and audio notifications on augmented reality devices is a crucial element of intuitive and easy-to-use interfaces. In this paper, we explored creating intuitive…
I Did Not Notice: A Comparison of Immersive Analytics with Augmented and Virtual Reality
Xiaoyan Zhou, Anil Ufuk Batmaz, Adam S. Williams +2
Immersive environments enable users to engage in embodied interaction, enhancing the sensemaking processes involved in completing tasks such as immersive analytics. Previous compar…
Data-driven Storytelling in Hybrid Immersive Display Environments
Xiaoyan Zhou, Yalong Yang, Francisco Ortega +2
Data-driven stories seek to inform and persuade audiences through the use of data visualisations and engaging narratives. These stories have now been highly optimised to be viewed…
Seeing virtual while acting real: Visual display and strategy effects on the time and precision of eye-hand coordination
A. U. Batmaz, M. de Mathelin, Birgitta Dresp-Langley
Effects of computer generated 2D and 3D views on the time and precision of bare-handed or tool-mediated eye-hand coordination were investigated in a pick-and-place-task with comple…
Effects of 2D and 3D image views on hand movement trajectories in the surgeons peripersonal space in a computer controlled simulator environment
AU Batmaz, M de Mathelin, Birgitta Dresp-Langley
In image-guided surgical tasks, the precision and timing of hand movements depend on the effectiveness of visual cues relative to specific target areas in the surgeons peri-persona…
Getting nowhere fast: trade-off between speed and precision in training to execute image-guided hand-tool movements
AU Batmaz, M de Mathelin, Birgitta Dresp-Langley
Background: The speed and precision with which objects are moved by hand or hand-tool interaction under image guidance depend on a specific type of visual and spatial sensorimotor…
