Guest Editorial Special Section on the 2011 IEEE International Symposium on Haptic Audio–Visual Environments and Games
T
HE 2011 IEEE International Symposium on Haptic Audio–Visual Environments and Games (HAVE 2011) and the Fourth International Workshop on Massively Multiuser Virtual Environments (MMVE 2011) jointly took place at Yanshan University, Qinhuangdao, China, from October 15 and 16, 2011. The HAVE 2011 marked the tenth edition of this annual workshop series, and it received more than 50 papers (not including MMVE 2011 submissions) from ten different countries and regions. Twenty-nine papers for HAVE 2011 and seven papers for MMVE 2011 were accepted for oral or poster presentation at the conference, resulting in seven sequential technical sessions. These papers covered many important topics on haptic, audio, and visual virtual environments and related applications, including haptic sensors, human haptics, haptosurgical/medical systems, haptic compression and prediction, multimodal perception and psychophysics, haptic game interfaces, telehaptics and teleoperation, augmented and virtualized reality, collaborative virtual environments, human–computer interaction in virtual environments, multisensor data fusion, object modeling, and soft computing techniques. While all accepted HAVE 2011 and MMVE 2011 papers that had been registered and presented at the conference were eligible to submit an extended version to this special section, only those manuscripts with genuine and substantial technical extension beyond the scope of the proceedings papers were considered. At the end, four papers were accepted to this special section after a rigorous review procedure as any other regular submission. In the paper “Optimal State Feedback Integral Control Using Network-Based Measurements” by Li et al., two different networked state-feedback integral control (SFIC) methods are presented to improve the disturbance rejection capability for a class of networked control systems (NCSs) in the presence of time delays and packet losses. One method is with guaranteed cost based on the SFIC, and the other one is the so-called estimation of distribution algorithm (EDA) based SFIC. The paper provides complete results on modeling, stability analysis, and controller synthesis of the proposed methods for the concerned NCSs. It was demonstrated that the proposed methods have better nonzero disturbance rejection capability and can achieve zero steady-state error.

The paper “Bilateral Teleoperation Design With/Without Gravity Measurement” by Hua and Yang tackles the problems associated with time-varying and asymmetrical transmission delays in networked teleoperation systems. They develop an adaptive torque control algorithm, for which an artificial initial force is applied to the human operator through the master robot to deal with cases where gravity is not available or serious collision with remote object is possible. The stability of the closed-loop teleoperation system is proved by using Lyapunov functional and verified through simulation study. In order to understand better the mechanism of human finger sensation, a 3-D nonhomogeneous finite element (FE) dynamic model of a primate fingertip is developed in the paper “A 3-D Non-Homogeneous FE Model of Human Fingertip Based on MRI Measurements” by Wang et al.. In this paper, a human fingertip is measured using a magnetic resonance imaging (MRI) system, and a 3-D mesh is then obtained and utilized to formulate a nonhomogeneous FE dynamic model for simulating the fingertip behaviors. With a constitutive model with elastic and viscous elements that govern the dynamic behaviors of individual tetrahedral FE, the proposed model is further extended to deal with contact interaction between the fingertip and an external instrument. In comparison with fingertip models reported in the literature, this model promises better accuracy of internal and external geometries and the capabilities of simulating dynamic and viscous behaviors of the human fingertip. Simulations and experiments have been performed with both a human finger and a fingertip phantom. The results are compared and used to provide the basis for further improvement of the proposed method. The last paper is “Measuring and Analyzing Migration Delay for the Computational Load Balancing of Distributed Virtual Simulations” by De Grande et al.. It presents a migrationaware balancing scheme to include migration latency analysis in its load redistribution algorithm for distributed virtual simulations of complex systems. Working in balancing cycles, the proposed system periodically monitors simulations to enable responsiveness to imbalances. Moreover, measurements of metrics related to federate migrations are used in the proposed balancing system to analyze and evaluate modifications on the load distribution. Extensions are also proposed in order to gain further performance improvement. Experiments have been conducted, and the reported experimental results have demonstrated improved performance of the proposed migration-aware balancing schemes.
