We introduce novel algorithms to generate interior structures that show the result of cutting generated by the interaction between instrument and model. Our simulator supports two types of cutting: 'cut-into', in which the instrument only penetrates the simulated tissue, and 'cut-through' in which the instrument cuts completely through. Haptic force feedback models for interaction between virtual instruments and object are also implemented, which allows the user to feel the contact forces through a haptic device.","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130270598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We based this system on the Nintendo Wii remote controller hardware. 3D site surveyor is able to detect movement of a user in three dimensions (x, y and z-axis), including rotation in the xy-plane (yaw). We will argue that, within the limits of the system, it is theoretically possible to also measure pitch and roll, making the system capable of detecting 6DoF. The system can be applied to, for example, gaming, virtual reality, ambient-assisted living and academic research (e.g., human motion, perception and attention).","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116435809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering a dynamic perspective, ambiguities can be caused by: inaccuracy in the user's drawing, approximation of the represented reality and user's deletion or retracing of fragments of the sketch. Moreover, this paper discusses methods to solve ambiguities taking into account the spatial and temporal information that characterise the user's drawing, deleting and over-tracing process according to some experimental observations of users' behaviour.","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125471241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Students can observe dynamic phenomena that are often difficult to explain by written material in laboratory environment.

Our approach is based on the newly developed software packages. Remote control, network reliability, and safety features are integrated into the experimental hardware and software design. Distance users are able to develop and run controllers on the experiments in the virtual laboratory, and can effectively use the laboratory from anywhere over internet.","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"40 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120837426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The internet, including multimedia, has provided tremendous potential for remote integration and collaboration in business applications.

It justifies the application of multimedia in various tourism sub-domains such as tourism marketing, tourism education, mobile learning for travellers, mobile tourism guides, multimedia kiosks, virtual museums, virtual tours, multimedia travel plans, cooking studios based on web recipes, video conferencing and modelling demand for space tourism services. A conceptual framework for the design of multimedia systems for tourism is presented and discussed.

In this paper, we propose an efficient moving object-extraction algorithm suitable for real-time content-based multimedia streaming systems. A motion vector based object extraction is used to dynamically detect the objects. To utilise the bandwidth efficiently, the video objects can be detected in real time, encoded, and transmitted with higher quality and a higher frame rate than those in the background. To meet the real-time requirement, no computationally intensive operation is included in this framework. Moreover, to guarantee the highest speed, the entire implementation is operating in the compressed domain without any need for decompression.","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125383535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We give a short overview of charging concepts in next generation mobile networks and we describe the most important network attributes on which the quality depends. Our goal is to point out the importance of bursty packet loss which determines the quality of the multimedia streaming in contrast with the average loss rate. We propose several methods for QoS differentiated charging which are in compliance with the recommendations of 3GPP. We describe three models which can predict the QoS of a stream. The algorithms are evaluated on a real GPRS streaming flow.","PeriodicalId":118986,"journal":{"name":"International Journal of Virtual Technology and Multimedia","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114824662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
