Haptic Collaboration Virtual Environment (HCVE) is an enhanced virtual reality space that supports sense of touch, which is called " haptic ". In HCVE, remote users connected over networks are able to collaborate by sharing touching experiences in addition to well-established audio and visual interfaces. The success of HCVE largely depends on timely(More)
The adoption of vibration interfaces in the games and the virtual reality is increasing since they improve the user experience. The principle of existing vibrating devices is to vibrate when detecting the presence of particular frequency bands. However such frequency-based scheme, according to our survey, cannot meet the user expectation; they vibrate too(More)
The tactile effects of a sound-specific vibration interface is presented in this paper. The sound-specific vibration interface generates a vibration according to a sound stream using 16 oscillators arranged in 4x4 array. By setting time frame, we were able to generate various patterns of vibrations. So, the main purpose of this paper is to analyze the(More)
In this paper, we mainly present the analysis on the haptic data transmission over real network conditions in a networked haptic collaboration environment. Since haptic data are produced at the rate of 1khz, the transmission of haptic data is extremely sensitive to packet loss, and time variation. We took some experiments for transferring haptic data under(More)
