Interaction Design of Dwell Selection Toward Gaze-based AR/VR Interaction

Toshiya Isomoto et al.

Summary: This paper starts by positioning the current dwell selection among gaze-based interactions and its advantages against head-gaze selection, then compares how these two selection methods are used in an actual interaction situation to describe the potential of dwell selection as an essential AR/VR interaction.

Comparison of Eye-Based and Controller-Based Selection in Virtual Reality

Wen-jun Hou et al.

Summary: This study explored the Fitts' modeling of eye-based selection in a virtual reality environment with controller-based input, finding that controller-based interaction offered the highest throughput, best accuracy, and was preferred by most participants. Eye-trigger interaction performed in between the other two, and showed better performance in terms of accuracy with three-dimensional targets. Eye-based interaction still requires a more stable and precise eye-tracking device to become a mainstream interaction modality in virtual reality, but has irreplaceable potential in specific VR environments.

Virtual reality and annotated radiological data as effective and motivating tools to help Social Sciences students learn neuroanatomy

Margot van Deursen et al.

Summary: The study compared the effectiveness of Virtual Reality (VR) and Radiological Data (RaD) as learning methods for neuroanatomy, finding that VR was more motivating and effective in improving student motivation and interest. The results suggest that VR is a diverting method that can effectively enhance learning outcomes in neuroanatomy.

Magnoramas: Magnifying Dioramas for Precise Annotations in Asymmetric 3D Teleconsultation

Kevin Yu et al.

Summary: This paper introduces a novel interaction method called Magnoramas, which enhances users' ability to perform supernaturally precise virtual annotations on virtual objects. The results show that Magnoramas significantly improve the precision of annotations while preserving usability and perceived presence measures compared to the baseline method.
