1A2-R03 VR中での鍵盤操作を対象とした力覚特性(VRとインタフェース)

There is currently much discussion of Quality of Service(QoS) measurement at the network level of real-time multimedia services. The presence of a network brings up a number of issues. In case of visual or auditory interaction, the effect of such issues have been treated by many researchers and the effective countermeasure have been proposed. A haptic Interface is a useful device in virtual reality technology and users can make a feeling of touching virtual object. Especially, in a virtual environment connected by a network system, users can share tasks and feelings. However, with a networked virtual environment, the haptic interface will make an unstable behavior because of a communication delay. This experiment focuses on a keyboard interface which uses haptic interacting with virtual space surrounding user. We have also constructed a 3D haptic interaction system, whereby the user can see and touch virtual objects by using a haptic device. However, new methods are known about the relationship between network issues and networked haptic interface in virtual environments. This experiment shows ethernet data transmission on purpose of packet delay and packet loss for transmission, with a few statistical analysis and traditional coding scheme.
