In this paper we describe a new way to improve the usability of complex hardware setups in Instrumented Environments (IEs). By introducing a virtual character, we facilitate intuitive interaction with our IE. The character is capable of freely moving along the walls of the room. In this way, it may offer situated assistance to users within the environment. We make use of a steerable projector a...

A room may be used for a wide variety of performances and presentations. Each use places different acoustical requirements on the room. We desire a method of electronically controlling the acoustical properties of a room so that one physical space can accommodate various uses. A virtual acoustic room is a room equipped with speakers, microphones and signal processors that functions as an intera...

This paper discusses challenges teachers faced due this dramatic transfer from habitual on-line classes. small-scale empirical research focuses on two questions: Which problems did face, which solutions they find overcome them? study also investigates techniques of synchr...

We applied a discourse analysis (DA) to the electronic chat room discussions of a 16-week, Internet-based section of a class in statistical methods in psychology. This analysis revealed that across the semester, several DA categories (e.g., total number of student comments) were correlated with final grade in the class. An additional analysis involving only the chat room discussion of Week 3 re...

In the field of eLearning systems, several systems have been implemented in order to create a virtual university or virtual training center. By connecting several virtual universities together, we extend the concept of an online university setting to a virtual world where there is richer interaction between the players. In this virtual world, several universities can interact, the best instruct...

Today’s digital era, dynamic teaching and learning in higher education has moved from traditional class room, face-to face learning environments to more interactive and collaborative environments, due to a demand for online-distance learning from students, and the desire from academic institutes to promote and deliver courses across the globe. Advancement in open source virtual learning platfor...
