Virtual reality systems may be used as a new educational tool because a user can be provided immersive sensation as he/she experiences a real object. A tiled display is one of the virtual reality systems which generates high-quality images and guarantees wide view angle using multiple projectors. In this work, we present a tiled display system which has high resolution screen (its resolution is 4096 x 1536 and its effective resolution is 3200x1200). We apply a seamless technique to this system in order to remove joint lines and to improve the quality of images. Furthermore, we implement educational contents for experiencing a CMOS manufacturing process based on the proposed tiled display system.

A tiled display is one of virtual reality systems which generate high-quality images and guarantee wide view angle using multiple projectors. The virtual reality systems may be used as a new educational tool because a user can be provided immersive sensation as he/she experiences a real object. Previously, we have proposed a tiled display system where a high resolution image is generated by binding multiple images obtained from multiple and low resolution projectors. We have also implemented the educational contents on the proposed tile display system. However, the system does not consider an interaction method which enables an instructor to control educational contents in front of screen. Therefore, this paper suggests realistic educational platform based on the interaction and automatic calibration.

In this paper, we suggest a haptic mouse system as an immersive interface between virtual environment and a human operator. The proposed haptic mouse creates vibrotacitle and thermal sensation to increase the immersion. The vibrotactile module is composed of eccentric motors and a solenoid actuator, and the thermal module consists of a thin-film resistance temperature detector and a Peltier thermoelectric heat pump. In order to evaluate the proposed haptic mouse system, we develop a simple racing game and conduct an experiment. The result of the experiment shows that the proposed haptic mouse system can improve the sense of reality in virtual environment and can be used as an effective interface between virtual environment and a human operator.
