In this paper, we carry out a transparency (i.e., haptic realism) analysis and propose a haptic synchronization scheme for a force-reflecting teleoperation over time-varying network delay. Although previous researches proposed several haptic synchronization schemes to efficiently compensate for delay jitter, defining a proper synchronization delay for transparency improvement remains a challenge....
In this paper, we carry out a transparency analysis and propose a haptic synchronization scheme for force-reflecting teleoperations such as a telerobotic game over time-varying network delays. The transparency analysis quantifies the force feedback distortion caused by network delay and packet loss, and predicts the maximally allowable delay and loss for predefined transparency requirements. In order...
With HPC (high performance computing) and scientific computing, it has been possible to produce a large amount of data. To easily analyze those data and collaborate on it, visualization in terms of ultra high resolution is desired. However, in order to combine a HPC system with a high resolution display system, high system resource is required. This paper shows an example of a system combining both...
Haptic-based NVEs (networked virtual environments) with CS (client/server) communication architectures support better consistency but induce larger end-to-end delays than those with P2P (peer-to-peer) communication architectures. Unfortunately, large delay severely deteriorates the transparency (i.e., reality) of haptic interaction. To improve the haptic interaction quality for haptic-based NVEs with...
