Hence, some haptic devices were developed to permit users touch digital objects surface. These studies mainly confuse on developing haptic hardware, and the algorithm for synthesizing input signals were not studied well. A surface roughness measurement and input vibration signal synthesis techniques are proposed. To measure the surface roughness, some photos are taken using a fixed camera when the lighting changes its incidence direction. A surface normal image is obtained from these photos. Then vibration signal as input signal of cutaneous tactile device is synthesized. Adding the friction sound, the cutaneous tactile is enhanced and can got touch feeling well even using simple vibration tactile device. The system is consisted by 3D visual display, force feedback device and vibration tactile device. The effect of this system is demonstrated using virtual ancient heritage objects at the end.","PeriodicalId":168094,"journal":{"name":"IEEE Conference on Visual Analytics Science and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222518","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}

In total, five different parts of numismatic research areas are identified: the classification of coins into given types, the identification of concrete coin specimens, the identification of coins struck by the same die, the reassembling of broken coin fragments and the segmentation and surveying of coins. For each application a problem description is given and the use of computer vision methods is discussed in detail. Additionally, for the image-based classification, identification and segmentation of coins results achieved so far are presented. Since computer vision methods are applied on photographs of coins, their acquisition (both in 2D and 3D) is covered as well.","PeriodicalId":168094,"journal":{"name":"IEEE Conference on Visual Analytics Science and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115544426","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}

This is particularly evident in extreme lighting conditions such as bright light or dark environments. However, it is simply not possible to represent such a range of lighting on a typical display today. This is about to change. The field of High Dynamic Range (HDR) imagery allows us to capture and display the full range of human vision. \u0000 \u0000The use of technologies in the preservation and dissemination of cultural heritage can play an important role in the representation and interpretation of our past legacy. A major field of application is virtual reconstructions of ancient historical environments. \u0000 \u0000In this domain, the way we see such (reconstructed) environments is particularly important in order to establish a correct interpretation of that historical setting. In this paper we present a case study of the reconstruction of a Roman site. We generate HDR images of mosaics and frescoes from one of the most impressive monuments in the ruins of Conimbriga, Portugal, an ancient city of the Roman Empire. We show that the HDR viewing paradigm is well suited for archaeological interpretation, since its high contrast and chromaticity can disclose and present us an enhanced viewing experience, closer to how the artefacts may have been perceived in the past. To achieve the requisite level of precision, in addition to a precise geometric 3D model, it is crucial to integrate in the virtual simulation authentic physical data of the light used in the period under consideration. Thereby in order to create a realistic physical based environment we use in our lighting simulations real data obtained from Roman luminaries of that time.","PeriodicalId":168094,"journal":{"name":"IEEE Conference on Visual Analytics Science and Technology","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122323268","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}

Both the authoring and the presentation views shall finally be as easy to use as, e.g., Microsoft Powerpoint. But instead of separated slides our tool uses pre-defined 3D scenes, called 'layouts', containing geometric objects acting as placeholders, called 'drop targets'. They can be replaced quite easily, in a drag-and-drop fashion, by digitized 3D models, and also by text and images, to customize and adapt a digital exhibition to the style of the real museum. Furthermore, the tool set contains easy-to-use tools for the rapid 3D modeling of simple geometry and for the alignment of given models to a common coordinate system. \u0000 \u0000The technical innovation is that the tool set is not a monolithic application. Instead it is completely based on scripted designs, using the OpenSG scene graph engine and the GML scripting language. This makes it extremely flexible: Anybody capable of drag-and-drop can design 3D exhibitions. Anybody capable of GML scripting can create new designs. And finally, we claim that the presentation setup of our designs is 'grandparent-compliant', meaning that it permits to the public audience the detailed inspection of beautiful cultural 3D objects without getting lost or feeling uncomfortable.","PeriodicalId":168094,"journal":{"name":"IEEE Conference on Visual Analytics Science and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115410545","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 uncertainty associated with an archaeologist's interpretation is represented using possibility theory and visualised by shader-based information visualisation schemes. An increase or decrease in uncertainty is influenced by any related evidence recovered; we define this evidence as 'influencing factors'. Different types of archaeological evidence were identified after discussions with several archaeologists. To understand the individual importance of each influencing factor on an interpretation, we analysed data derived from formal questionnaires distributed to a selected group of archaeologists equally divided between Roman and non-Roman specialists. They were asked questions ranging from the wider perception of uncertainty to more specific ones on the identified types of archaeological evidence. We describe the stages involved in designing the questions, the process of gathering data and feedback from archaeologists, and the results themselves. Results suggest that specific evidence types are considered more favourably than others.","PeriodicalId":168094,"journal":{"name":"IEEE Conference on Visual Analytics Science and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128566767","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}
