Virtual Reality technology has been becoming popular. As fascinating virtual worlds have become more accessible, we may feel compelled to photograph the virtual world. However, real world photography and virtual world photography are not the same experiences. For example, traditional virtual world photography methods do not allow for failures to occur, which is a factor in enjoying the photographic experiences. In this paper, we propose a virtual space photography system that can simulate shooting with a real camera as an interface and allow for shooting failures. We specifically generate images that consider the motion blur of the exposure by the shutter. We demonstrate the possibilities of generating failed photos that function as a kind of memory by simulating the effect of taking a picture with a real world camera.
This paper describes a support system for tracheal suction skill acquisition based on augmented reality technology. A few tracheal suction skill training tools have already been developed and used, but its operating cost is expensive, such as maintenance, storage, and cleaning/drying/sterilization after use as well as its purchase cost. Besides, the tracheal suction skill is a procedure inside the trachea, it is difficult to observe and evaluate the skill because the state of the procedure is to be invisible directly. Our proposed system solves these existing tools problems using augmented reality technology and compact 3D printing models and sensors. The system validity has been verified by evaluation experiments.
Virtual Reality (VR) contents have been becoming popular. However, VR would certainly cause VR motion sickness. One of the main factors in VR motion sickness might be the discrepancy between the predicted physical experiences and the actual physical experiences. To prevent such discrepancy, an approach is effective that synchronizes the user's physical movements in the virtual space with the user's somatosensory movements. There has been developed a VR system which provides such a somatosensory interface. However, it is too huge, expensive and difficult to operate.
In this paper, we propose a simple somatosensory interface for moving virtual space by imitating swimming motions. The users of our system move the virtual space like to swim in the water by the kicks of both foot and the strokes of both arms. We developed a sensory interface that measures user's imitating swimming motions by four gyro sensors. Each gyro sensor is a 9-axis gyro sensor, including a 3-axis angular velocity sensor, a 3-axis acceleration sensor, and a 3-axis geomagnetic sensor. Four gyro sensors measure the movements of the strokes of both arms and kicks of both feet, respectively.
Five students evaluated our interface. They use our interface to navigate the specified course. After that, they answered the questionnaires. Experimental results verified that our interface was useful and effective for moving the virtual space without causing VR motion sickness.
