Tele-emergency services provide immediate and synchronous audio/video connections, most commonly between rural low-volume hospitals and an urban "hub" emergency department. We performed a systematic literature review to identify tele-emergency models and outcomes. We then studied a large tele-emergency service in the upper Midwest. We sent a user survey to all seventy-one hospitals that used th...

The provision of mental health services via videoconferencing tele-mental health has become an increasingly routine component of mental health service delivery throughout the world. Emphasizing the research literature since 2003, we examine: 1) the extent to which the field of tele-mental health has advanced the research agenda previously suggested; and 2) implications for tele-mental health ca...

This paper presents the architecture and implementation of a tele-presence wheelchair system based on tele-presence robot, intelligent wheelchair, and touch screen technologies. The tele-presence wheelchair system consists of a commercial electric wheelchair, an add-on tele-presence interaction module, and a touchable live video image based user interface (called TIUI). The tele-presence intera...

We propose a dynamic load balancing scheme for the tele-traac hot spot problem in cellular networks. A tele-traac hot spot is a region of adjacent hot cells where the channel demand has exceeded a certain threshold. A hot spot is depicted as a stack of hexagonaìRings' of cells and is classiied as complete if all cells within it are hot. Otherwise it is termed incomplete. The rings containing al...

In the rush into cyberspace we leave our physical presence and our real-world environment behind. The internet, undoubtedly a remarkable modern communications tool, still does not empower us to enter the ooce of the person at the other end of the connection. We cannot look out their window, admire their furniture, talk to their ooce mates, tour their laboratory, or walk outside. We lack the equ...

Tele-immersive 3D multi camera environments are beginning to emerge and they bring with them lots of applications as well as challenging research problems. They enable cooperative interaction between geographically distributed sites. One of the important questions that arises in the design and implementation of such systems is that how to transmit huge amounts of 3D data consisting of multiple ...
