Sanal gerçekliğin ruh sağlığı alanında kullanımı, bilgisayarlı modeller yoluyla insan algılarının yapay nesne ve yerlerle gerçekte varmışçasına değiştirilmesine dayalıdır. gerçeklik maruz bırakma terapisi, güvenli, ekonomik kontrol edilebilir bir yöntem olması nedeniyle tercih edilmektedir. Diğer yandan sanal uygulamalarının geliştirilmesinin karmaşıklığı, kullanılan donanımların yüksek maliyet...

We present a conceptual framework that introduces key concepts capturing initial trust establishment in on-demand Virtual Organisations (VO). This framework can be used to develop trust formation protocols and policies. The framework can serve as a basis for implementing an automated system that facilitates the establishment of a VO, considerably reduces the effort for setting up a VO and conse...

We proposed a switchable beam steering device with cycloidal diffractive waveplate (CDW) for eye tracking in a virtual reality (VR) or augmented reality (AR) display system. Such a CDW diffracts the incident circularly polarized light to the first order with over 95% efficiency. To convert the input linearly polarized light to right-handed or left-handed circular polarization, we developed a br...

Awe is a little-studied emotion with a great transformative potential. Therefore, the interest toward the study of awe's underlying mechanisms has been increased. Specifically, researchers have been interested in how to reproduce intense feelings of awe within laboratory conditions. It has been proposed that the use of virtual reality (VR) could be an effective way to induce awe in controlled e...

BACKGROUND Examining changes in brain activation linked with emotion-inducing stimuli is essential to the study of emotions. Due to the ecological potential of techniques such as virtual reality (VR), inspection of whether brain activation in response to emotional stimuli can be modulated by the three-dimensional (3D) properties of the images is important. OBJECTIVE The current study sought t...

By using cloud computing it is possible to provide on- demand resources for epidemic analysis using computer intensive applications like SaTScan. Using 15 virtual machines (VM) on the Nimbus cloud we were able to reduce the total execution time for the same ensemble run from 8896 seconds in a single machine to 842 seconds in the cloud. Using the caBIG tools and our iterative software developmen...

In recent years, there has been considerable interest in the development of treatments to help people reduce their public speaking anxiety (PSA) in a variety of circumstances. A review of literature suggests that several treatments have been found to be effective in reducing communication apprehension. However, it has not been determined whether Virtual Reality Therapy (VRT) has proven to be as...

Augmented Reality (AR) refers to superimposing computer generated objects onto a real world scene. The use of AR as a surgical planning aid is a compelling application and several demonstrations of its potential have been produced. This paper looks at the impact AR can also make on training medical procedures. In particular, we look at building an AR environment though the use of wellestablishe...
