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

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

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 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

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

Our implementation is flexible, allowing either multi-touch or interaction, or even a hybrid scheme to better suit user choice and convenience. Different TangiWheel aspects and features are compared with other existing widgets for collection manipulation. The study reveals that TangiWheel is the first proposal to support a hybrid input modality with large resemblance levels between touch and tangible interaction styles. Several experiments were conducted to evaluate the techniques used in each input scheme for a better understanding of tangible surface interfaces in complex tasks performed by a single user （e.g., involving a typical master-slave exploration pattern）. The results show that tangibles perform significantly better than fingers, despite dealing with a greater number of interactions, in situations that require a large number of acquisitions and basic manipulation tasks such as establishing location and orientation. However, when users have to perform multiple exploration and selection operations that do not require previous basic manipulation tasks, for instance when collections are fixed in the interface layout, touch input is significantly better in terms of required time and number of actions. Finally, when a more elastic collection layout or more complex additional insertion or displacement operations are needed, the hybrid and tangible approaches clearly outperform finger-based interactions.展开更多
