iran’s industry has had a considerable number of difficulties to perform so well as was expected in the post – revolutionary era. unfavorable legal, political environments combined with eight –year imposed war may be singled out as the root causes of such performances. however, this paper argues that our industry’s lack of realization of its dire need to adapt to the emerging unprecedented envi...

This chapter reviews contemporary research on virtual collaboration. In particular, we focus on synchronous communication and collaboration processes in virtual conferencing environments. In a virtual conference, interactants are geographically distant but their avatars (virtual representations) appear in the same virtual conference room. Two types of virtual collaboration are examined. First, ...

Effective control of the perceived location of virtual sound sources is an important aspect of auditory displays. While room acoustics modelling may be used to produce cues related to the sound source and listener location in a space, in many real-time applications it is more feasible to utilize ready-made room impulse responses. This paper looks at how the perception of distance can be affecte...

An I-Room is an “intelligent room” which can act as a knowledge aid to support collaborative meetings and activities, especially when these involve sense-making about the current context, planning, considering options, and decision-making. The I-Room provides a generic technology basis for a wide range of potential collaborative applications and uses. It can provide a conduit for accessing inte...

BACKGROUND Context conditioning has been suggested to model clinical anxiety, but context, as manipulated in animal models, has not been translated to human studies. A virtual environment might prove to be the ideal tool for innovative experimental paradigms to study explicitly cued fear and contextual anxiety in humans. METHODS Subjects were guided through a virtual environment that consiste...

In this paper high-quality model-based sound synthesis of plucked string and woodwind instruments is combined with room simulation and auralization techniques. The result is a real-time virtual three-dimensional room where the listener and multiple virtual instruments can be moved. The system was designed using signal processors in a multiprocessing environment. Sound radiation patterns of musi...

This study examined the effects of two variables on spatial learning: the objects’ array (with or without a central reference point) and the learning method (virtual walk through or seeing still images). After learning the objects’ locations and their positional relations in a virtual room in egocentric reference frames, participants judged the directions to a target from an imaginary position ...

COVID-19 pandemic in 2020 digitizes human activities. The educational field is one of the aspects that affected. classroom activities usually do with teacher and students together room moves to virtual class which are apart. teachers charged be more creative make an interactive class. There various applications, purpose non-educational purpose, can used teaching learning Thus, this study aimed ...
