본 논문에서는 감각형 객체(Tangible Object)를 이용한 테이블에서의 2D/3D 상호작용 시스템을 제안한다. 제안된 시스템은 기존의 ARTable[1]에 직육면체 형태의 감각형 객체와 카메라가 장착된 이동형 모니터를 추가하여 제작되었다. 감각형 객체는 모든 면에 ARToolkit[3]에서 쓰이는 마커가 부착되어 있으며, 내부에는 진동자와 불루투스 통신 모듈이 삽입되어 있다. 또한 카메라가 달린 모니터는 모니터 암에 연결되어 사용자가 이동하며 ARTable 상판을 관측할 수 있도록 부착되어 있다. 이 시스템를 이용하여 사용자는 디스플레이형 테이블인 ARTable 위에서 가상공간을 네비게이션(2D 상호작용)할 때 정확한 길을 찾아가기 위한 도움을 받을 수 있을 뿐만 아니라, 증강현실 환경에서 가상객체와 3D 상호작용을 할 수 있다. 또한 진동 모듈과 이를 제어하기 위한 블루투스 모듈이 내장 되어있어, 특정한 이벤트 발생시 진동자를 이용하여 사용자에게 촉각 감응 효과를 줄 수 있다. 제안된 시스템은 교육, 엔터테이먼트, 등 다양한 분야에서 사용될 수 있다.

Haptics technology allows one to interact with virtual environments, augmented environments, and real environments providing tactual sensory information. Science and technology of haptics can in general be classified into three groups: machine haptics, computer haptics, and human haptics. This paper surveys the state-of-the-art of haptic control technology for virtual environments and teleoperation (real environments) and then proposes possible future research directions in the following areas: haptic stability control, bilateral teleoperation control, and stability enhancement control.

This paper proposes the physical human-robot interaction method that controls the robot arms using ITO touch panel sensor as the skin of robot. To implement physical human-robot interaction, the method of using the force/torque sensor and the method of using tactile sensor created by arranging small element type of sensor have been studied. However, these sensors have the pros and cons in terms of price and performance. This study aims to demonstrate the economy of element type sensor and the accuracy of force/torque sensor through experiment by proposing the method of physical interaction using the touch panel as the skin of robot, and by constructing overall system. The experiment was carried out for the method of controlling the robot arm by installing end-effecter and the method of controlling robot arm by creating the gesture with reference point on the touch panel. Through this experiment, the possibility of teaching control using the touch panel was confirmed.

This paper proposes a user interface for enhancing immersiveness and usability by combining hologram and haptic device with common Leap Motion. While Leap Motion delivers physical motion of user hand to control virtual environment, it is limited to handle virtual hands on screen and interact with virtual environment in one way. In our system, hologram is coupled with Leap Motion to improve user immersiveness by arranging real and virtual hands in the same place. Moreover, we provide a interaction prototype of sense by designing a haptic device to convey touch sense in virtual environment to user's hand.
