In this paper we report on the navigation in a virtual environment by the output signal of an EEG-based Brain-Computer Interface (BCI). Such a BCI transforms bioelectrical brain signals, modified by mental activity into a control signal. At this time only 1-D or 2-D BCI feedbacks are used. The graphical possibilities of virtual reality (VR) should help to improve BCI-feedback presentations and ...
The purpose of this survey is provision of a conceptual model for identification andcategorization of skills required for virtual student. Special environment of virtuallearning has posed inevitable necessities which should be considered: skills requiredfor virtual student is identified and categorized. Two main questions of the researchinclude: 1- What properties does have virtual learning env...
the current research tries to offer a conceptual model in order to create trust among people for choosing virtual universities. to this end, the conceptual model of research has been designed with nine factors. the relationship among factors tested by using statistical methods such as factor analysis and path analysis. in the end, five components were established from among the affecting factor...
Abstract Introduction: Library is one of the essential elements of universities which provide some important educational needs of students. Virtual education can not be exempted and virtual libraries are important support for virtual training programs. The purpose of this study is to evaluate the viewpoint of administrators and students in virtual education centers about the virtual library, it...
Galvanic vestibular stimulation (GVS) evokes a perception of rotation; however, very few quantitative data exist on the matter. We performed psychophysical experiments on virtual rotations experienced when binaural bipolar electrical stimulation is applied over the mastoids. We also performed analogous real whole body yaw rotation experiments, allowing us to compare the frequency response of ve...
