Three-dimensional VR interaction using the movement of a mobile display

In this study, we propose a VR system for allowing various types of interaction with virtual objects using an autostereoscopic mobile display and an accelerometer. The system obtains the orientation and motion information from the accelerometer attached to the mobile display and reflects them to the motion of virtual objects. It can present 3D images with motion parallax by estimating the position of the user's viewpoint and by displaying properly projected images. Furthermore, our method enables to connect the real space and the virtual space seamlessly through the mobile display by determining the coordinate system so that one of the horizontal surfaces in the virtual space coincides with the display surface. To show the effectiveness of this concept, we implemented an application to simulate food cooking by regarding the mobile display as a frying pan.
