Gesture control interface for immersive panoramic displays

In this paper, we propose a gesture-based interface designed to interact with panoramic scenes. The system combines novel static gestures with a fast hand tracking method. Our proposal is to use static gestures as shortcuts to activate functionalities of t ...

Parallelization of the distinct lattice spring model

Jiannong Fang, Liang Sun, Jian Zhao, Gaofeng Zhao

The distinct lattice spring model (DLSM) is a newly developed numerical tool for modeling rock dynamics problems, i.e. dynamic failure and wave propagation. In this paper, parallelization of DLSM is presented. With the development of parallel computing tec ...

Chip-Level Redundancy in Distributed Shared-Memory Multiprocessors

Babak Falsafi

Distributed shared-memory (DSM) multi- processors provide a scalable hardware platform, but lack the necessary redundancy for mainframe-level reliability and availability. Chip-level redundancy in a DSM server faces a key challenge: the increased latency t ...

On scaling strategies for the full-body postural control of virtual mannequins

Daniel Thalmann, Ronan Boulic, Damien Maupu

Due to its intrinsic complexity. full-body postural input has been Mostly limited to off-line motion capture and to on-line Puppetry of a virtual character with little interaction with its environment (e.g. floor). The motion capture technology is now matu ...

Impulse Radio Ultra-Wideband Ranging Algorithm under Multi User Environments

Jean-Yves Le Boudec, John Farserotu, Hai Zhan

Practical impulse radio ultra-wideband (IR-UWB) ranging systems always have to work in multi-user and weak non-line-of-sight (NLOS) environments. In this paper, we derive a novel IR-UWB ranging estimator under multi-user and weak NLOS environments. We mode ...
