This paper aims at introducing 'CyberDome', a PC-Clustered Projection Based VR Display, where the illusion of immersion is realized by projecting stereo images into a hemi-spherical screen. With the help of our developed distortion correction software, the system is capable of displaying life size, stereoscopic, distortion free images on the screen with a(More)
Modification and reuse of digital contents, particularly web data, has become easy due to advancement in computer technology. The work created by a person (or a group of persons) can be reused by another person (or group) for different purpose. Thus, there can be multiple copyright holders for the same information. In such scenario, it is important to(More)
In this study, we developed a compact wireless Laplacian electrode module for electromyograms (EMGs). One of the advantages of the Laplacian electrode configuration is that EMGs obtained with it are expected to be sensitive to the firing of the muscle directly beneath the measurement site. The performance of the developed electrode module was investigated(More)
BACKGROUND Laparoscopic surgeons require extended experience of cases to overcome the lack of depth perception on a two-dimensional (2D) display. Although a three-dimensional (3D) display was reported to be useful over two decades ago, 3D systems have not been widely used. Recently, we developed a novel 3D dome-shaped display (3DD) system, CyberDome. (More)
We developed a compact wireless electrode containing an amplifier, a filter and a transmitter to measure the Laplacian electromyogram (Laplacian EMG) using the source derivation method. We made a character input system by connecting a circuit converting Laplacian EMG signals to clicks, with a personal computer in which a software for scanning character(More)
