Modern information technologies are transforming the way people learn. E-learning provides new possibilities for personalized learning at home or in the workplace, reduces the need for costly classroom training, and enables an optimal balance between traditional and innovative forms of knowledge transfer. But facts have proven that content creation for online courses is time-consuming and costl...

Tele-immersion is one of the applications being developed in conjunction with the Internet-2 initiative. Most of the research in this area has focused on issues pertaining to image acquisition and display, tracking technologies, robotics, haptics, etc. In order to maintain consistency of a tele-immersive experience one also needs to develop a suit of solutions that will ensure proper coordinati...

This paper proposes an overview of a study that conceptually unify the fields of virtual reality and teleoperation, by analyzing the notion of “assistance” to the operator of a virtual reality or tele-operation system. This analysis demonstrates that cases of assistance that are usually considered to belong to virtual reality are not conceptually different from what has been done in tele-operat...

Telemedicine for the intensive care unit (Tele-ICU) was founded as a means of delivering the clinical expertise of intensivists located remotely to hospitals with inadequate access to intensive care specialists. This was a retrospective pre- and postintervention study of adult patients admitted to a community hospital ICU. The patients in the preintervention period (n = 630) and during the Tele...

The paper describes the development of a high-performance system for visualizing complex scientific models in real-time. The architecure of the system is a client/server model, in which the simulator generates lists of 3D graphics objects in parallel to the simulation, from where they are sent to a streaming server. The server transfers the 3D objects to viewer clients. Clients communicate over...

An der Universität Trier wurde eine neue, drastisch vereinfachte Zugangstechnik für Online-Vorlesungen namens tele-TASK (Teleteaching Anywhere Solution Kit) [TELE] [MS02] mit Erfolg erprobt. Von der Wohnung oder vom Büro aus kann dadurch jeder PC-Nutzer mit geeignetem Internetanschluss ob interessierter Laie, Fachspezialist oder eingeschriebener Student Lehrveranstaltungen komfortabel mitverfol...

This systematic review aimed to identify how tele-mentoring systems that incorporate augmented reality (AR) technology are being used in healthcare environments. A total of 12 electronic bibliographic databases were searched using the terms “augmented reality”, “tele-mentoring” and “health”. The PRISMA checklist was as a guide for reporting. mixed method appraisal tool assess quality included e...

In this paper we present why tele-monitoring is a promising application domain for Ubiquitous Computing. We discuss how the characteristics of ubiquitous information systems can be applied in the design of tele-monitoring applications and what special conditions and problems have to be regarded. Finally, we present the results of the implementation of such an application realized in a joint res...

This paper discusses the value of identifying the expanding interdisciplinary scholarly literature on the topic of (tele)presence, proposes a detailed procedure for doing so, and presents a list of 1,831 journal articles, books and other publications that constitute the (tele)presence literature as of May 2007.
