Virtual Reality (VR) is one of the newest technological domains with revolutionary applicability for the tomorrow’s Future Internet, including visions of the Internet of Things. The sensation of total immersion in Virtual Environment (VE) is still unresolved. Therefore, our work proposes a new omnidirectional locomotion interface for navigation in VEs. The novel interface was built from an ordi...

majority of models in location literature are based on assumptions such as point demand, absence of competitors, as well as monopoly in location, products, and services. however in real-world applications, these assumptions are not well-matched with reality. in this study, a new mixed integer nonlinear programming model based on weighted goal programming approach is proposed to maximize the cap...

We are aiming at developing an online collaborative framework allowing Deaf individuals to author intelligible signs using a dedicated authoring interface controlling the animation of a 3D avatar. In this paper, we present the results that we have achieved so far. They mainly focus on the design of a User Interface assisted by novel input devices. In particular, we show, in two user studies, ho...

We propose a new design for inspection and reverse engineering environments. We have designed and experimented with such an environinent for capturing sense data of niechaniccil parts in an intelligent way. We construct a sensing -+ CAD interface for the automatic recoiistruction of parts from visual data. We briefly discuss the use of the dynamic recursive finite state machine (DRFSM) as a new...

Refraction of black and gray solitons at boundaries separating different defocusing Kerr media is analyzed within a Helmholtz framework. A universal nonlinear Snell’s law is derived that describes gray soliton refraction, in addition to capturing the behavior of bright and black Kerr solitons at interfaces. Key regimes, defined by beam and interface characteristics, are identified and predictio...

This paper describes a conceptual model of an e-learning framework designed for capturing semantic tier data from users. The model is based on the two-tier semantic e-learning framework (DSi), developed at the Faculty of Electronic Engineering, Niš. The existing framework expands textual e-learning material with a semantic layer, while providing intuitive drag-and-drop user interface for queryi...

This paper describes a sensory system for implementing a human-computer interface based on electrooculography. An acquisition system captures electrooculograms and transmits them via the ZigBee protocol. The data acquired are analysed in real time using a microcontroller-based platform running the Linux operating system. The continuous wavelet transform and neural network are used to process an...

In a task-based approach to user interface development, the task model is given a leading role among other models. Task modeling is a key activity in the design of a usable user interface. Task patterns that are based on both task and domain models are typical interaction structures that are capturing operations performed onto domain objects. This paper is discussing some key requirements for a...

Process choreographies describe interactions between different business partners and the dependencies between these interactions. While different proposals were made for capturing choreographies at an implementation level, it remains unclear how choreographies should be described on a conceptual level. While the Business Process Modeling Notation (BPMN) is already in use for describing choreogr...

A central feature that scientists are interested in is the dynamics of fluid interfaces or the so called material boundaries in multi-fluid simulation . Visualization techniques for capturing fluid interface are based on one of about three basic algorithms. In this paper, we give a survey of the existing interface tracking algorithms, including backgrounds, terms, procedures as well as pointers...
