ABSTRACT
Augmented reality (AR) technology is a technique of superimposing information
generated by a computer on perceptual information that we receive from
real space. Recently, much attention has been focused on interaction techniques
between users and virtual objects, such as the user directly manipulating
virtual objects with his/her bare hands. On the other hand, in AR technology,
since the 3-dimensional (3D) model is superimposed on the image of the
real space afterwards, it is always displayed on the front side than the
hand. Thus, it becomes an unnatural scene in some cases (occlusion problem).
In this study, this system considers the object-context relations between
the user's hand and the virtual object by acquiring depth information of
the user's finger. In the evaluation experiment, it is confirmed that the
hidden surface removal in this study not only makes it possible to consider
the object-context relations but also can distinguish between finger boundaries
and to clarify and process finger contours.
