An often heard critique on the use of ICT in a heritage context is the individualized nature of the experience. Group communication is an important aspect within a cultural experience, because it can encourage participants to interact with one another and to stimulate each other. Another aspect of great importance is the blending in of the virtual and the real achieved by using context based in...

1 Most part of this paper was written in 2008. Minor revision was made in 2014. ABSTRACT Existing digital technologies in urban settings tend to focus narrowly on concerns around wayfinding, safety, and consumption. In this paper, we examine pedestrian experiences based on the data collected through field observations as well as intensive interviews with nine pedestrians in the Shibuya area of ...

Thesis supervision is an important activity in higher education with Bachelor's and Master's theses mandatory parts of university programmes. In traditional education, thesis supervision has been a face-to-face activity, but today, both the student groups and the learning environments are blended. This study describes and discusses the design and implementation of a blended learning environment...

In constructive solid geometry (CSG), highly smooth and manageable blending operations are always desirable. In this paper, we propose two novel ways to blend implicitly defined geometric objects using smooth unit step functions. With the proposed techniques, not only is it direct to build an implicit blending operation with controllable blending range, but also the blending operation can be co...

Following the Bayesian framework we propose a method to reconstruct emission tomography images which uses gamma mixture prior and variational methods to approximate the posterior distribution of the unknown parameters and image instead of estimating them by using the Evidence Analysis or alternating between the estimation of parameters and image (Iterated Conditional Mode (ICM)) approach. By an...

Résumé. Dans cet article nous proposons une modification pour l’algorithme "Iterated Conditional Modes" (ICM) appliqué à la segmentation d’images à très haute résolution. Pour ce faire, nous introduisons un nouveau critère de convergence basé sur la compacité des clusters et qui repose sur une fonction d’énergie adaptée aux modèles de voisinages irréguliers de ce type d’images. Grâce à cette mé...

Conceptual blending is a cognitive theory whereby elements from diverse, but structurally-related, mental spaces are ‘blended’ giving rise to new conceptual spaces. This study focuses on structural blending utilising an algorithmic formalisation for conceptual blending applied to harmonic concepts. More specifically, it investigates the ability of the system to produce meaningful blends between...

Conceptual blending is a powerful tool for computational creativity where, for example, the properties of two harmonic spaces may be combined in a consistent manner to produce a novel harmonic space. However, deciding about the importance of property features in the input spaces and evaluating the results of conceptual blending is a nontrivial task. In the specific case of musical harmony, defi...

Collaborative environments have been evolving and effectively employed in large organisations and are believed to have high potential for Small and Medium Enterprises (SMEs). This chapter shares the findings of a case study that was conducted on twelve companies in order to assess the use of collaborative environments and their adaptation approaches through interviews with senior level managers...

We describe our work on human-computer cooperative dialogue, that uses special "active" logics in an attempt to more closely and more usefully model human behavior. This effort pays attention to a number of issues, including Gricean pragmatics, logical nonomniscience, reasoning with inconsistent data, limited memory, blending in new information during reasoning, and models of human communicatio...
