Mixed reality technologies, such as virtual (VR) and augmented (AR) reality, present
promising opportunities to advance education and professional training due to their …

The vergence-accommodation conflict (VAC) limits user performance in current Virtual
Reality (VR) systems. In this paper, we investigate the effects of the VAC in a single-focal VR …

We explored how interaction performance is affected by multi-depth VR targeting and button
selection using two targeting methods: eye tracking with no UX modifications and feedback …

Fitts' law is a standard tool for assessing user performance and interaction device
effectiveness in human-computer interaction (HCI). However, it disregards spatial variables …

When working in Virtual Reality (VR), the user's performance is affected by how the user
holds the input device (eg, controller), typically using either a precision or a power grip …

Handray selection is widely used for hand-tracking-based interactions in head-mounted
displays, as it is a simple and straightforward interaction technique. However, selection …

Fitts' law is widely used as an evaluation tool for pointing or selection tasks, evolving into
diverse applications, including 3D extended reality (XR) environments like virtual …
