Background: According to the situation of education in Iran it is clear that over the years, there has been no successful attempt to identify related challenges and problems to development and implementation of virtual training. In this regard, the effect of this type of training influenced by the role of hidden curriculum of education in the country.   Based on this, current study has investig...

This paper proposes a pseudo-haptic feedback method conveying simulated soft surface stiffness information through a visual interface. The method exploits a combination of two feedback techniques, namely visual feedback of soft surface deformation and control of the indenter avatar speed, to convey stiffness information of a simulated surface of a soft object in virtual environments. The propos...

In this paper we present our latest approach for 2D hand tracking in video streams of head-worn monocular color cameras. Those are lightweight and embedded in many head-mounted devices (HMDs) like eye trackers, Augmented Reality glasses or Virtual Reality devices to capture the field of view from the ego perspective. Interaction with virtual elements of the augmented or virtual reality or the i...

The invention The invention relates to a virtual monitor and method for virtualizing a " non-privileged " computer instruction having at least two types of execution behavior, depending on prior events and on a current privilege level. The invention is described in more detail in the Findings of Fact. The claims Claims 1, 9, and 10 are reproduced below: 1. A method for virtualizing a non-privil...

In this paper, we propose an efficient and discriminative model for salient object detection. Our method is carried out in a stepwise mechanism based on both divergence background and compact foreground cues. In order to effectively enhance the distinction between nodes along object boundaries and the similarity among object regions, a graph is constructed by introducing the concept of virtual ...

introduction: virtual bronchoscopy is a reliable and efficient diagnostic method for primary symptoms of lung cancer. the segmentation of airways from ct images is a critical step for numerous virtual bronchoscopy applications. materials and methods: to overcome the limitations of the fuzzy connectedness method, the proposed technique, called fuzzy connectivity - fuzzy c-mean (fc-fcm), utilized...

Keywords: Gear fault diagnosis Virtual prototype Wavelet AR model PCA a b s t r a c t Gear systems are an essential element widely used in a variety of industrial applications. Since approximately 80% of the breakdowns in transmission machinery are caused by gear failure, the efficiency of early fault detection and accurate fault diagnosis are therefore critical to normal machinery operations. ...

Virtual property theft is a serious problem that exists in virtual worlds. Legitimate users of these worlds invest considerable amounts of time, effort and real-world money into obtaining virtual property, but unfortunately, are becoming victims of theft in high numbers. It is reported that there are over 1 billion registered users of virtual worlds containing virtual property items worth an es...
