TUIs show a potential to enhance the way in which people interact with digital information. First, this paper exam- ines the existing body of work on tangible user interfaces and discusses their application domains, especially information visualiza- tion. Then it provides a definition of intuitive use and reviews formerly separated ideas on physicality. As interaction has an impact on the overall product experience, we also discuss whether intuitive use influences the users＇ aesthetic judgements of such products.展开更多

That is, both 3D polygonal and image-based representations are maintained for an object, and switched for rendering depending on the functional requirement of the object. Furthermore, in order to reduce the popping effect and provide smooth and gradual transition during the object representation switch, the object is subdivided with the subdivided parts possibly represented differently, i.e., using 3D models or images. As for the image-based representation, the relief texture (RT) method is used. In particular, through the use of the mixed representation, a new way called TangibleScreen is pro-posed to provide object tangibility by associating the image-based representation with a physical prop (projecting the RTs) in a selective and flexible way. Overall, the proposed method provides a way to maintain an interactive frame rate with selective perceptual details in a large-scale virtual environment, while allowing the user to interact with virtual objects in a tangible way.展开更多

Its applications into design education have been explored with a limi-tation to this entire area. TAR offers an innovative learning space by merging digital learning materials into the format of media with tools or objects which are direct parts of the physical space. It is therefore conceived that such combination opens new perspectives in teaching and learning. This paper presented and evaluated one TAR system to improve the pedagogical effectiveness of experiential and collaborative learning process in urban design education. The results from the experiments were analyzed under a previously developed theoretical framework, which show that TAR can enhance the design activities in some collaborative work.展开更多

On a theoretical level, scholars propose variations to the models by removing the theoretical hypothesis or expanding variables considered, likewise, on an empirical level, researchers provide survey, which contributions aimed at increasing the understanding of the phenomenon as a whole, considering the possible events in the variety and variability of firms. In particular, one of the most debated topics in the literature regards the existence or absence of relationship between the choices of financial structure and firm value, or the determination of an optimal leverage for the value. Therefore, the attention of researchers has focused on the identification of relationship between debt and equity that maximizes firm＇s performance and meet shareholders＇ expectations in terms of return on capital employed for the same risk. Hence, the aim of this paper is to provide another piece to the cognitive complexity of the phenomenon, focusing the research on Italian firms, given the importance of leverage in the financial structure of Italian firms. The methodology used is based on the analysis conducted using the Mediobanca database aggregated sector by sector to identify the main determinants of financial structure. The conclusion is that it is not possible to say with certainty which financial structure theory better represents the behavior of Italian firms concerning financial structure.展开更多

In this paper, various acoustic source localization methods are proposed which have the potential to covert a physical object into a tracking sensitive interface. The Spatial Likelihood method has been used to locate acoustic source in real time by summing the spatial likelihood from all sensors. The source location is obtained from searching the maximum in the likelihood map. The data collected from the sensors is pre-processed and filtered for improvement of the accuracy of source localization. Finally a sensor fusion algorithm based on least squared error is presented to minimize the error while positioning the source. Promising results have been achieved experimentally for the application of acoustic tangible interfaces.展开更多

Thereby, each rotation is induced by the spin of one electron?[1]. Hereto, a tangible mechanical model was used which facilitated to derive the mathematical formulae as the basics for two-dimensional projections, and—not least—for a digital animation yielding freeze images from different perspectives. The resulting shape of the electron shell turned out to be not spherical. In particular, the total velocity of the electrons is variable since the relative running direction may change—in contrast to the initial assumption—, even leading to an intermittent standstill, and implying a variable kinetic energy. Thus it can be concluded that this model describes a rotating rotor but not the Helium atom, and that it must be abandoned.展开更多

In view of this, historic blocks and ancient buildings are taken as the key points of restoring collective memory spaces of cities, and Temple of Lord Fan Wenzheng in ancient Huishan Town, Wuxi City as a typical case to define tangible landscape elements in memory spaces. By analyzing the process of restoring buildings, pavements, waters, stone layouts and plants in the temple, practical means of restoring tangible landscapes in city memory spaces were summarized, so as to provide references for protecting original town landscapes, repairing damaged memory spaces, and inheriting city memories.展开更多

And this will influence much on enterprises for the new rules are more adjusted in many aspects. Through comparing with the old assets rules, the paper has analyzed the characteristics of the new assets devaluating rules. Compared with the old rules, the more different characteristics are that in the new rules, assets devaluating confirmation is defined, tangible amount calculation is prescribed in detail, the conception of ＂Assets Group＂ is raised for the first time, and the processing method of creditworthiness is set. The most important thing is that the new rules provide that once the assets devaluating preparation is confirmed, it will not be withdraw. At the same times, from comparing the confirmation of devaluating assets, tangible amount and dealing with devaluating loss, assets devaluating influence of the new rules and the old on enterprises＇ profit and loss is analyzed and an instance is used in the analysis.展开更多
