ClockRay: A Wrist-Rotation Based Technique for Occluded-Target Selection in Virtual Reality.

Target selection is one of essential operation made available by interaction techniques in virtual reality (VR) environments. However, effectively positioning or selecting occluded objects is under-investigated in VR, especially in the context of high-density or a high-dimensional data visualization with VR. In this paper, we propose ClockRay, an occluded-object selection technique that can maximize the intrinsic human wrist rotation skills through the integration of emerging ray selection techniques in VR environments.

User capabilities in eyes-free spatial target acquisition in immersive virtual reality environments.

In immersive virtual reality (VR) environments, users rely on the vision channel to search for objects. Such eyes-engaged interactive techniques may significantly degrade the interaction efficiency and user experience, particularly when users have to turn their head frequently to search for a target object in the limited field of view (FOV) of a head-mounted display (HMD). In this study, we systematically investigated user capabilities in eyes-free spatial target acquisition considering different horizontal angles, vertical angles, distances from the user's body, and body sides.

Design and development of an immersive virtual reality news application: a case study of the SARS event.

In recent years, virtual reality (VR) technologies have been applied to the field of journalism, where the concept of immersive VR news has been proposed. However, despite the fanfare, strong response, and sensational effect caused by its advent, immersive VR news remains a novel journalism paradigm that faces new challenges in its production process. Currently, there is a lack of a unified design framework, and, since most studies in this area have focused on non-interactive VR news, the understanding of the effects of more interactive VR technologies on the news consumer remains inadequate.
