“…N. Kato, H. Ishigaki, S. Suzuki, and M. Sato [4] introduced a flexible virtual object by using a physics engine, and realized deformation manipulation of the virtual object through interaction with the user by reflecting the crushing motion with bare hands on the virtual object. In addition, R. Suzuki, S. Suzuki, M. Sato [5] realized the movement operation of a rigid virtual object by user interaction. However, operations such as maintaining the deformed shape, moving, and merging have not been realized for flexible virtual objects.…”

In recent years, there has been a lot of research on how to achieve interaction between users and virtual objects using augmented reality. Interaction technologies in augmented reality need to enable users to handle virtual objects intuitively. In addition, since hands are the main means of interaction with objects in real life, it is also necessary to enable interaction operations with hands on virtual objects [1]. In order to make it possible to intuitively handle objects in virtual space using hands in real space, it is necessary to consider whether physical phenomena in real space and virtual space are correctly superimposed (physical consistency). In this study, we proposed a system that allows users to intuitively handle the deformation, movement, and merging of virtual objects in augmented reality. The system was then used by four university students to compare it with existing studies [2].

“…Kato et al [4] introduced flexible body virtual objects by using Bullet Physics (or physics engine), reflecting the action of crushing on the virtual object with the user's bare hand in the virtual space, and realized the deformation manipulation of virtual objects by interaction with the user. Suzuki et al [5] depicted the moving manipulation of rigid body virtual objects through an interaction between the user and virtual objects. However, after deforming the virtual object, moving or rejoining the virtual object while maintaining the original shape was not possible.…”

Augmented Reality (AR) is a technological advancement which brings to reality the intuitive interaction that a user is attracted to virtual objects. In this paper, we focus on intuitive manipulation of virtual objects with bare hands. Specifically, we propose a method to deform, move, and join virtual objects by intuitive gestures, and aim at intuitive interactions with virtual objects. In order to manipulate virtual objects with bare hands, the position coordinates of the user's fingers are acquired using the Leap Motion Controller. Additionally, we use Bullet Physics as an engine to represent virtual objects. On the other hand, in AR technology, since the three-dimensional (3D) model is superimposed on the image of the real space afterward, it is always displayed on the front end rather than the user's hand (occlusion problem). Thus, the user cannot perform an intuitive manipulation. We solve the occlusion problem by performing appropriate hidden surface removal. From the results of a study using data gathered from a questionnaire survey, we found support for the intuitive interaction between the user and virtual objects.

Recently, studies for realizing interaction between users and virtual objects using Augmented Reality (AR) have been actively conducted. However, few previous studies have realized that a user intuitively manipulates virtual objects like clay with their bare hands. In this study, we aim at user's intuitive virtual objects manipulation by realizing basic manipulation on virtual objects with their bare hands. In addition, it is considered that the user feels uncomfortable in the manipulation of the virtual objects because of the occlusion problem in AR, and cannot perform an intuitive manipulation. Therefore, in this study, we solve this problem by performing appropriate hidden surface processing within the range of the user's fingertips.
