This manuscript identifies and documents unsolved problems and research challenges in
the extended reality (XR) domain (ie, virtual (VR), augmented (AR), and mixed reality (MR)) …

Recent work on augmented reality (AR) has explored the use of adaptive agents to
overcome attentional issues that negatively impact task performance. However, despite …

Virtual Reality (VR) systems have traditionally required users to operate the user interface
with controllers in mid-air. More recent VR systems, however, integrate cameras to track the …

Gestural interaction has evolved from a set of novel interaction techniques developed in
research labs, to a dominant interaction modality used by millions of users everyday …

Hand gestures are a natural and intuitive form for human-environment interaction and can
be used as an input alternative in human-computer interaction (HCI) to enhance usability …

Uncomfortable sensations that arise during virtual reality (VR) use have always been among
the industry's biggest challenges. While certain VR-induced effects, such as cybersickness …

This work presents the design and evaluation of a set of three mini exercise games
(exergames), called “Ellic's Exercise Class,” which allows people to play in virtual reality …

Immersive robotic avatars have the potential to aid and replace humans in a variety of
applications such as telemedicine and search-and-rescue operations, reducing the need for …

A prerequisite to improving the presence of a user in mixed reality (MR) is the ability to
measure and quantify presence. Traditionally, subjective questionnaires have been used to …
