AbstractThis paper reviews high-speed optical 3D sensing technologies for obtaining the 3D shape of a target using a camera. The focusing speed is from 100 to 1000 fps, exceeding normal camera frame rates, which are typically 30 fps. In particular, contactless, active, and real-time systems are introduced. Also, three example applications of this type of sensing technology are introduced, including surface reconstruction from time-sequential depth images, high-speed 3D user interaction, and high-speed digital archiving.

The Brazilian Symposium on Virtual and Augmented Reality (SVR) celebrated its 10th edition in 2008, in the city of João Pessoa. During these last 10 years, SVR has earned its space and magnitude as a truly consolidated event within the Brazilian research community. The papers in this special issue of RITA were selectively chosen among the 24 full papers presented in SVR 2008. They are extended and revised versions of those originally presented in the symposium. The material in this special issue is representative of the wide scope of the areas covered by the symposium. The first paper, the only one not presented at the symposium, was written by the editors jointly with Luciano Soares and Veronica Teichrieb. It provides a rich panorama of current Brazilian research in Virtual Reality (VR) and related areas, based on an analysis of the 124 full papers presented over the last four SVR editions. The second paper, by Silvano Malfatti, Selan dos Santos, Luciane Fraga, Claudia Justel, Paulo Rosa, and Jauvane Oliveira, describes some interesting VR work. Its authors present an engine (EnCIMA) aimed at the quick development of VR applications. The third paper, by Fábio Miranda, Romero Tori, Cláudio Bueno, and Lucas Trias, presents research results from the Augmented Reality (AR) area. This paper, which received the best paper award in the symposium, presents a projection-based AR X-Ray tool to allow visual exploration of internal details of walls, as an illustration. The fourth paper, by Leandro Fernandes, Vitor Pamplona, João Prauchner, Luciana Nedel, and Manuel Oliveira, explores 3D user interaction. It presents the implementation of a data glove that uses a camera to track visual markers at finger tips. Finally, the last paper, by Ednaldo Pizzolato, Diego Duarte, and Marcio Fernandes, explores speech recognition as a form of interaction, introducing a software framework for application developers.

Problems associated with the improve ment of information retrieval for open environment are considered and the need for it’s semantization is grounded. Thecurrent state and prospects of development of semantic search engines that are focused on the Web information resources processing are analysed, the criteria for the classification of such systems are reviewed. In this analysis the significant attention is paid to the semantic search use of ontologies that contain knowledge about the subject area and the search users. The sources of ontological knowledge and methods of their processing for the improvement of the search procedures are considered. Examples of semantic search systems that use structured query languages (eg, SPARQL), lists of keywords and queries in natural language are proposed. Such criteria for the classification of semantic search engines like architecture, coupling, transparency, user context, modification requests, ontology structure, etc. are considered. Different ways of support of semantic and otology based modification of user queries that improve the completeness and accuracy of the search are analyzed. On base of analysis of the properties of existing semantic search engines in terms of these criteria, the areas for further improvement of these systems are selected: the development of metasearch systems, semantic modification of user requests, the determination of an user-acceptable transparency level of the search procedures, flexibility of domain knowledge management tools, increasing productivity and scalability. In addition, the development of means of semantic Web search needs in use of some external knowledge base which contains knowledge about the domain of user information needs, and in providing the users with the ability to independent selection of knowledge that is used in the search process. There is necessary to take into account the history of user interaction with the retrieval system and the search context for personalization of the query results and their ordering in accordance with the user information needs. All these aspects were taken into account in the design and implementation of semantic search engine "MAIPS" that is based on an ontological model of users and resources cooperation into the Web.
