Telecommunication service has been growing and progressing from telephone to high reality communication systems that are based on evolution of network and media technologies. Recognizing virtual reality (VR) as a communication tool, we provide a review of communication services and the directions they are moving in, as well as related VR technologies. The Immersive Telepresence System "Kirari!" is also introduced as the latest development example for a new telecommunication service.

“…Many other methods for practicing situation assessment have been proposed, such as a system that displays an actual game scene and situation using a head mounted display or immersive projection display using computer graphics [14][15][16][17]. However, these methods have the problem that there is no interactivity with a real body (such as a ball or an opponent) and there are differences in the perception of the image from the real world.…”

“…Some of these approaches involve the improvement of training methods and schedules [1,2], development of new equipment [3,4], improvement of existing equipment [5], tactical analysis, and strategic planning [6]. More and more efforts are being put in to enhance sports training using technology [11,[13][14][15], particularly in ball game sports. This is because it is difficult to reproduce the same scene and optimize the training level in ball game sports using traditional methods.…”

This study presents a system that consists of three machines to imitate the motion of top volleyball blockers. In a volleyball match, it is essential to improve the hitting percentage of each spiker in order to score by spiking. Iterative spiking training is required for increasing the hitting percentage. Therefore, we develop a block machine system that can be continuously used in an actual practice field for improving attack practice. Each machine is equipped with five degrees of freedom to achieve the required operating speed and mechanical strength. The machine performs high-speed movements on 9,000 mm rails that are arranged parallel to the volleyball net. In addition, an application with a graphical user interface enables a coach to manipulate these machines. It enables the coach to control block motions and change the parameters such as the machines' position and operation timing. We evaluate the feasibility of the proposed block form through practical use of the system in the practice field and confirm that the system has potential for improving attack efficiency.

A holographic mirror is a reflection-type holographic optical element that works as an off-axis mirror. It realizes an upright see-through screen serving as a virtualimage display and virtual camera. Such screen enables to realize virtual-imagebased attractive applications like Pepper's ghost only with a thin optical system. This chapter describes the concept of a holographic-mirror-based virtual-image display and virtual camera, an experimental method for exposing the holographic mirror based on holographic printing, methods for dispersion compensation, and experimental results for the proposed virtual-image display and camera.
