The introduction of spatial audio features into conventional teleconferencing systems is a natural way of creating a realistic communication environment and was introduced many years ago. The human auditory system takes advantage of spatial audio cues to locate, separate and understand multiple speakers when they talk simultaneously. As a result, speech intelligibility is significantly improved...

purpose: to assess various aspects of integrating a virtual reality (vr) simulator in the training of ophthalmology residents methods: in this qualitative study, some aspects of the vr eyesi simulator as a health technology were assessed. data was collected using a multiple-choice questionnaire and several deep interviews addressed to users and administrators of simulator training. face and con...

One of the characteristics of BETA [4] is the unification of abstraction mechanisms such as class, procedure, process type, generic class, interface, etc. into one abstraction mechanism: the pattern. In addition to keeping the language small, the unification has given a systematic treatment of all abstraction mechanisms and leads to a number of new possibilities. One of the interesting results ...

Compression of 3D object based video is relevant for 3D Immersive applications. Nevertheless, the perceptual aspects of the degradation introduced by codecs for meshes and point clouds are not well understood. In this paper we evaluate the subjective and objective degradations introduced by such codecs in a state of art 3D immersive virtual room. In the 3D immersive virtual room, users are capt...

This paper proposes a novel algorithm Virtual Instances Resampling Technique Using Active Learning (VIRTUAL) for class imbalance problem in Support Vector Machine (SVM) learning. In supervised learning, prediction performance of the classification algorithms deteriorate when the training set is imbalanced. Class imbalance problem occurs when at least one of the classes are represented by substa...

In this paper we propose a method to simulate a 3D acoustical environment in which sound sources are positioned in well defined sides. Our method is real-time applications oriented, due to the low computational cost of the implemented operations. The spatial position that human brain assigns to a sound is influenced mainly by the differences between the sound signals that reach the listener’s e...

In this study, pairs of subjects performed a team-intensive task with the shared goal of clearing a virtual room from threats. The neurobehavioral dynamics of both subjects was analyzed to identify signatures of efficient team work. An ecologically valid task of room clearing was designed and a novel analysis framework was developed to address the challenge of understanding complex, continuous ...

Smart phones are becoming more and more powerful. Services that were traditionally designed for a static environment can now be implemented into mobile devices. One such service is Interactive Social TV, which allows geographically dispersed people to meet in a virtual shared space and watch TV while being able to interact with each other. This paper presents two novel architectures of a Mobile...
