Virtual Reality (VR) has been proven to be capable of enabling its users to experience immersive virtual environments and interact with the computer. Most VR applications utilize stereo visual perception, however, stereo visual perception alone is not enough to fully immerse users in VR environments. Haptic feedback technology when applied to VR applications can offer improved immersion and interactivity and can extend the range of sensations experienced by the user. For example, tactile feedback can enable the user to feel an object they touch with their virtual hand or body. To provide tactile feedback in VR applications most researchers construct cumbersome mechanical actuators and linkages for applying feedback forces or vibrations to the user's real hand or body. Having to wear cumbersome feedback hardware can have the negative effect of making the user more aware of their physical body which can reduce the sense of being immersed in the VR world. To overcome this drawback we propose an alternative feedback system which is comprised of a hand gesture interface, a stereo visual head-set and an electro-tactile feedback system. Our electro-tactile feedback system is compact, simple, inexpensive and capable of delivering a variety of feedback sensations to the user. Experimental results are provided which demonstrate how the electro-tactile feedback system can enhance both the sense of immersion and interactivity for VR users.

The paper presents a prototyped jointed control interface approach for understanding hapticised web content and augmented reality (AR) on a work-in-progress instructive platform of haptics (IPOH) over the unreliable network. Our works, in this context, are comprised by two parts. Firstly, we propose a joint user interface SPIDAR-if empowering finger tracking and physical force sense. SPIDAR-if includes a recently notable pocket-sized 3D sensor named “Leap Motion” as an input device and incorporates with another passive 2-degree-of-freedom (DOF) tactile device “SPIDAR” with upturned manipulations in order to truly represent the sense of touch interactions on IPOH system, such as tactile feedbacks derived from in-progressive verbs, HTML components and moving 3D spheres. On the other side, we study the eligibility of SPIDAR-if and its aids with regard to AR world and web content intelligibility in IPOH system which offers the Internet users a bridge to embrace virtual reality by virtue of assisted user interface, wrapping up haptic and web graphical rendering techniques as well as provided virtual environments (VE). Examples of hapticised web content and a 3D AR scenario approaching SPIDAR-if on IPOH with the fingertip are also presented along with preliminary findings.

—Recently, the strategic approaches of public sector organizations are reevaluated in order to achieve modern effective operations and provide better services to their customers (citizens and businesses). Business Process Management (BPM) solutions are recognized as essential tools for public services transformation, as they enable public organizations to be more efficient, to meet business challenges rapidly and flexibly, and to improve the customers experience by resolving incidents and responding to requests in a timely fashion. Within this context, this paper describes the development of a BPM System (BPMS) as a part of a web-based integrated system for benchmarking, monitoring, simulation and redesigning processes. This system will be deployed initially in Municipalities and later on in several Greek government agencies, in order to offer more efficient, personalized and consistent services to citizens and businesses, in a reduced operational cost. The paper presents the methodological approach followed for BPMS development. It also highlights system's functionality and its usefulness in process design, benchmarking, redesign and continuous improvement.

—Applying temporal constraint in planning is a well-known problem, which keeps a plan is flexible until a specific schedule is generated. In this area, Decoupled Multi-agent simple temporal problem (DMaSTP) is suitably applied for planning of a multi-agents system. However, in scheduling problem, new events or temporal constraints are added regularly and force scheduler to check the consistency of exist MaSTP and retighten exist constraints. In this paper, we study a distributed scheduling algorithm for incrementally solving a DMaSTP. We have strongly considered the problem of adding a set of new constraints into a tightening consistent DMaSTP that tightened by also a distributed algorithm or set as empty. The algorithm checks whether the new adding constraints threaten the consistence of DMaSTP or not and decouple such new adding constraints when necessary and retighten DMaSTP. We have proposed a distributed algorithm, called DI-DMaSTP that solves the above problem and theoretically prove its correctness and outperformance, besides we have experienced with the variant datasets.

We discuss the methodology we have used, which is a variation of contextual design, and resulting prototypes for a platform that will provide functionality for users to interact with augmented reality features in cultural and historical places, which are referred to as points of interest. Also, we report on preliminary results of the evaluation of our prototypes with potential users.

—The problem of terminal sliding mode controller design for chaos control in memristor-based oscillators is investigated. The main goal is to stabilize the chaotic Chua's memristor-based oscillator and to track the sinusoidal reference input. The stability of the oscillator with terminal sliding mode control is analyzed using Lyapunov criteria. Moreover, by defining a new objective function, genetic algorithm optimization is used to reduce the chattering effect and to decrease the convergence time of terminal sliding mode controller. Simulation results demonstrate the usefulness of the proposed control method.
