In this paper, the analysis and design of a motion simulator (based on the approach taken by interactive virtual reality (VR) entertainment systems) is conducted. The main components of the system include a bilateral control interface, simulation and a motion simulator control scheme. The space entertainment system uses a virtual environment that enables operators to feel the actual feedback sensing and distorted motion from the virtual environment, just as they would in the real environment. The space entertainment system integrates the dynamics of the motion simulator and the virtual environment and the operator maneuvers a steering wheel to interact with the system. The multiple bilateral control schemes employ a dynamical controller, which is designed by considering the velocity and acceleration that the operator imposes on the joystick, the environmental changes imposed on the motion simulator. In addition, we develop a calculated method to evaluate the Ratio of the simulation results. It is shown that the proposed control scheme can improve the performance of the visual entertainment system. Experiments are conducted on the virtual reality entertainment system to validate the theoretical developments.

Virtual reality (VR) simulators have been extended to transfer knowledge and education, and demands for exhibition systems for science education and cultural experiences has also increased. Existing VR simulators, which are based on the dynamics equations of motion, cannot easily be adapted to changes in simulation contents. In order to effectively transfer knowledge and maintain interests through educational applications, an experiential system that has multi-sensory effects as well as motion effects is required. In this study, we designed and implemented a motion generation that is tailored to experiential exhibition systems and multi-sensory VR effects. Both the sense of motion which is generated from the movement of the viewpoint of the visual image, and motion effects which are constructed in advance, are applied to motion simulation. Motion effects which occur during interaction between the user and the exhibition system can be easily added. Various sensory cues that are appropriate to the exhibition system are also considered.

A patient with respiratory disorders such as a sleep apnea is increasing as the obese patient increase on the modern society. Positive Airway Pressure (PAP) devices are used in curing patient with respiratory disorders and turn out to be efficacious for patients of 75%. However, these devices are required for evaluating their performance to improve their performance by the mechanical breathing simulator. Recently, the mechanical breathing simulator was studied by the real time feedback control. However, the mechanical breathing simulator by an open loop control was specially required in order to analyze the effect of flow rate and pressure after operating the breathing auxiliary devices. Therefore the aims of this study were to make the mechanical breathing simulator by a piston motion and a valve function from the characteristic test of valve and motor, and to duplicate the flow rate and pressure profiles of some breathing patterns: normal and three disorder patterns. The mechanical simulator is composed cylinder, valve, ball screw and the motor. Also, the characteristic test of the motor and the valve were accomplished in order to define the relationship between the characteristics of simulator and the breathing profiles. Then, the flow rate and pressure profile of human breathing patterns were duplicated by the control of motor and valve. The result showed that the simulator reasonably duplicated the characteristics of human patterns: normal, obstructive sleep apnea (OSA), mild hypopnea with snore and mouth expiration patterns. However, we need to improve this simulator in detail and to validate this method for other patterns.

Vertigo refers to a state in which awareness related to the location, posture, movement, etc. of a helicopter is insufficient in space. It is easy to fall into flight illusion when flying in dense fog or night flight, and even if it has a wide field of view, it can be caused by visual causes such as cloud shapes, wind conditions, conditions of ground objects, and sensory causes such as changes in air posture or gravitational acceleration. The design and program of the motion system are studied that applied a six-axis motion system to a conventional commercial flight simulator program for pilot training, depending on the specificity of helicopter flight training that requires perception and sensitivity. Using the motion-based helicopter simulator produced in this study to train pilots, it is expected to have a positive effect in prevent of vertigo, where high performance could not be confirmed in the previously used visual-based simulation training device. 비행착각(Vertigo)이란 공간상에서 헬리콥터의 위치, 자세, 움직임 등과 관련된 인지가 부족한 상태를 일컫는다. 짙은 안개 속이나 야간비행 등, 지평선이 보이지 않는 상황에서 비행할 때 비행착각에 빠지기 쉽고 시야가 넓더라도 구름 모양이나 바람 등 기상 조건, 지상물의 상태 등 시각적인 원인, 기체의 자세나 중력가속도의 변화 등과 같은 감각적인 원인에 의해 빠지기도 한다. 조종사 비행 훈련에 있어 지각 및 감각을 요구하는 헬리콥터 비행 훈련의 특수성에 따라 조종사 훈련을 위해 기존의 상용 비행 시뮬레이터 프로그램에 6축 모션 시스템을 적용한 모의비행훈련장치 모션 시스템의 설계와 프로그램에 관하여 연구하였다. 본 연구를 통해 제작된 모션 기반 헬리콥터 시뮬레이터를 활용하여 조종사의 훈련에 활용할 경우 기존에 활용되던 시각 기반 모의비행훈련장치에서 높은 성과를 확인할 수 없었던 비행착각 예방에 긍정적인 효과가 나올 것으로 예상된다.

Numerous studies have been performed to analyze various phenomena of human"s walking, gait. In the present study, unrecognized walking and recognized walking were analyzed by three dimensional motion capture system(VICON motion system Ltd., England) and simulated by computer program. Two normal males participated in measuring the motion of unrecognized and recognized walking. Six infrared cameras and four force plates were used and sixteen reflective markers were attached to the subject to capture the motion. A musculoskeletal model was generated anatomically by using ADAMS(MSC software corp., USA) and LifeMOD(Biomechanics Research Group Inc, USA). The inverse dynamic simulation and forward dynamic simulation were also performed. The result of simulation was similar to the experimental result. This study provides the base line for dynamic simulation of the falling walking. It will be useful to simulate various another pathologic gaits for old peoples.

One of the main concerns of automotive industry is autonomous vehicles. Not only equipment suppliers but also new entering actors are racing to develop safer automotive systems. Consequently, the car manufacturer has to integrate different systems to control the same vehicle. This paper discusses the different architectures adopted to handle chassis systems interactions. Several car manufacturers study the influence of each system on the overall vehicle. They then add an additional coordination layer downstream the different systems to mitigate their possible conflicts. Here we propose a new approach that consists on managing systems interaction upstream the different systems. Coordination is based on control allocation techniques that take into account several vehicle states to find optimal commands distribution. Both approaches have been compared. Simulations showed the benefits that could offer the upstream approach in terms of safety and flexibility. The relevance of this approach is expected to grow with the increasing number of chassis systems.

The article deals with the analysis of driver interaction based on the road departure prevention system(RDPS). Firstly, the controller of the RDPS, which uses the linear quadratic regulator(LQR) method, is modeled. The controller is identified by the two-degree-of-freedom vehicle model and the steering model. The various weight coefficients of LQR are investigated through the vehicle driving trajectory. The performances of the RDPS model are validated with various lateral velocities in the straight road and the curved road, respectively. Then, the driver interaction based on RDPS is carried out in the driving simulator. The motion of the driver is analyzed by using motion capture devices. The results show that the vehicle is unstable when the driver intervenes with the RDPS. Also, when the RDPS was intervened by the driver, the right curved road was more unstable than the left curved road.
