“…Hands and controllers are common interaction methods in VR, and they provide the same actions [24][25][26]. Controllers are widely used to manipulate virtual objects and to enhance user immersion and haptic feedback [25].…”

Purpose Many surgical complications can be prevented by careful operation planning and preoperative evaluation of the anatomical features. Virtual dental implant planning in three-dimensional stereoscopic virtual reality environment has advantages over three-dimensional projections on two-dimensional screens. In the virtual environment, the anatomical areas of the body can be assessed and interacted with in six degrees-of-freedom. Our aim was to make a preliminary evaluation of how professional users perceive the use of the virtual environment on their field. Methods We prepared a novel implementation of a virtual dental implant planning system and conducted a small-scale user study with four dentomaxillofacial radiologists to evaluate the usability of direct and indirect interaction in a planning task. Results We found that all four participants ranked direct interaction, planning the implant placement without handles, to be better than the indirect condition where the implant model had handles. Conclusion The radiologists valued the three-dimensional environment for three-dimensional object manipulation even if usability issues of the handles affected the feel of use and the evaluation results. Direct interaction was seen as easy, accurate, and natural.

“…The degree to which a user can to perceive a virtual environment through the sensorimotor contingencies they would encounter in the physical environment is termed "immersion" (Slater and Sanchez-Vives, 2016). The subjective experience of being in a highly-immersive virtual environment is known as "presence", and recent empirical evidence suggests that being able to see one's tracked hands animated in real time in a virtual environment is an extremely compelling method of engagement (Voigt-Antons et al, 2020). Research has shown that we have an almost preternatural sense of our hand's positions and shape when they are obscured (Dieter et al, 2014), and when our hands are removed from our visual worlds it is a stark reminder of our disembodiment.…”

Hand tracking has become an integral feature of recent generations of immersive virtual reality head-mounted displays. With the widespread adoption of this feature, hardware engineers and software developers are faced with an exciting array of opportunities and a number of challenges, mostly in relation to the human user. In this article, I outline what I see as the main possibilities for hand tracking to add value to immersive virtual reality as well as some of the potential challenges in the context of the psychology and neuroscience of the human user. It is hoped that this paper serves as a roadmap for the development of best practices in the field for the development of subsequent generations of hand tracking and virtual reality technologies.

“…Hands are the main input method for any VR application, while hand tracking allows a natural representation of the user's hands. Hand tracking is a very powerful tool since it provides an increased sense of presence and immersiveness [41], and is more user-friendly given that there is no need for the user to learn how to use the controllers. Figure 1 shows how the hands of the user are rendered in the platform.…”

INTRODUCTION:Self-attachment is a new self-administrable psychotherapeutic intervention based on creating an affectional bond between the user and their childhood-self using their childhood photos to develop the capacity for affect self-regulation. Technological advances, such as virtual reality (VR), can enhance the procedure of this intervention and make it scalable. METHODS:We have developed a user-friendly, interactive VR platform for self-attachment featuring a virtual assistant and a customised child avatar that resembles the user in their childhood. The virtual agent interacts with the user and using an emotion recognition algorithm can provide suggestions for the user to undertake an appropriate self-attachment sub-protocol. Furthermore, the platform allows user interaction with the child avatar, such as embracing the avatar. RESULTS:We show by a small preliminary trial that such a VR experience can be realistic, leading to a positive emotion change in the user.
