Cyber-physical smart city integration of digitalcomponents into the real world will offer a variety of possibilitiesto enrich our daily life. A digital-physical hybrid world makes itpossible to optimize our energy use and to offer morecomfortable traffic management. However, we still need to investigate how to interact with a hybrid world. Augmentedreality and virtual reality techniques offer promising...
In this paper, we introduce a novel touristic trip suggestion system to facilitate the traveling of mobile users in a given city. Given the current user location and his touristic destination, our system can suggest a shortest trip path that visits as many popular landmarks as possible. To this end, we collect geographical tagged photos from Flickr [1] and Panoramio [2] photo sharing websites. Then...
We present a low bit rate vocabulary coding scheme in the context of mobile landmark search. Our scheme exploits location cues to boost a compact subset of visual vocabulary, which is discriminative for visual search and incurs low bit rate query for efficient upstream wireless transmission. To validate the coding scheme, we have developed mobile landmark search prototype systems within typical areas...
This paper introduces Sapporo World Window, a screen-based application that is currently under development for the new underway passage at the centre of Sapporo City. There are ten large public screens installed in the space, displaying user-generated videos about various aspects of the city and a real-time map that visualises users' interaction with the city. The application aims to engage the general...
It is not difficult to understand that telecommunication technologies can provide comfort as well as improve the quality of our everyday life. What isn't so evident are the environmental impacts of such developments. While telecommunication technologies are still seen as ??clean technologies??, they can have some harmful impacts on the environment, many of which have been identified and the protection...
This paper looks at the growing phenomenon of urban screens - large-scale LED screens in prominent city centre locations - and asks fundamental questions about the nature of the spaces and locations in which they are placed. In this investigation three key themes come to light that have a critical impact on the experience of urban space: namely, the mediation of place and locality, the distinction...
Rich online map interaction represents a useful tool to get multimedia information related to physical places. With this type of systems, users can automatically compute the optimal route for a trip or to look for entertainment places or hotels near their actual position. Standard maps are defined as a fusion of layers, where each one contains specific data such height, streets, or a particular business...
