“…Similar to precise object manipulation, controllers performed better than bare hands for imprecise object manipulation tasks. Huang et al [42] evaluated two-handed hybrid interaction methods, where all four combinations of using either hand tracking or a controller in each hand were tried in four different tasks. The results showed that the interaction system with controllers in both hands was the most efficient.…”

Virtual reality devices are used for several application domains, such as medicine, entertainment, marketing and training. A handheld controller is the common interaction method for direct object manipulation in virtual reality environments. Using hands would be a straightforward way to directly manipulate objects in the virtual environment if hand-tracking technology were reliable enough. In recent comparison studies, hand-based systems compared unfavorably against the handheld controllers in task completion times and accuracy. In our controlled study, we compare these two interaction techniques with a new hybrid interaction technique which combines the controller tracking with hand gestures for a rigid object manipulation task. The results demonstrate that the hybrid interaction technique is the most preferred because it is intuitive, easy to use, fast, reliable and it provides haptic feedback resembling the real-world object grab. This suggests that there is a trade-off between naturalness, task accuracy and task completion time when using these direct manipulation interaction techniques, and participants prefer to use interaction techniques that provide a balance between these three factors.

“…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]. Controllers are stable and accurate, which is crucial in dental implantation.…”

“…Controllers are stable and accurate, which is crucial in dental implantation. Huang et al [ 25 ] found that users generally executed the game-like tasks more efficiently with controllers in both hands than with a controller in one hand or without any controllers. As a downside, the handheld controllers may cause arm fatigue.…”

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.

“…Oculus Touch, Valve Index) use capacitive sensors for the fngers, providing a good trade-of between ofering the efcient tracking of a controller and more precise fnger movements for manipulating objects. It would also be interesting to study the impact of hybrid input [43] (using both a controller and hand tracking) on the sense of embodiment (see research topic RT3).…”

Avatars, the users' virtual representations, are becoming ubiquitous in virtual reality applications. In this context, the avatar becomes the medium which enables users to manipulate objects in the virtual environment. It also becomes the users' main spatial reference, which can not only alter their interaction with the virtual environment, but also the perception of themselves. In this paper, we review and analyse the current state-of-the-art for 3D object manipulation and the sense of embodiment. Our analysis is twofold. First, we discuss the impact that the avatar can have on object manipulation. Second, we discuss how the diferent components of a manipulation technique (i.e. input, control and feedback) can infuence the user's sense of embodiment. Throughout the analysis, we crystallise our discussion with practical guidelines for VR application designers and we propose several research topics towards "avatar-friendly" manipulation techniques.
