The aim of this study is to investigate teachers’ perceptions of their practice of values education, and to explore their degree of professionalism in this matter. Qualitative interviews with 13 teachers have been conducted and analysed by a comparative analysis. According to their view, values education is (a) most often reactive and unplanned, (b) embedded in everyday school life with a focus...

He has published over 180 papers in journals and international conferences on high-fidelity graphics, multi-sensory perception, virtual archaeology and parallel rendering. He is Honorary President of Afrigraph and a former Vice President of ACM SIGGRAPH. His research goal is 'RealVirtuality', obtaining physically-based, multi-sensory, virtual environments at interactive rates through a combinat...

This article seeks to establish a rapprochement between explicitly Bayesian models of contextual effects in perception and neural network models of such effects, particularly the connectionist interactive activation (IA) model of perception. The article is in part an historical review and in part a tutorial, reviewing the probabilistic Bayesian approach to understanding perception and how it ma...

Traditional accounts of language processing suggest that monologue--presenting and listening to speeches--should be more straightforward than dialogue--holding a conversation. This is clearly not the case. We argue that conversation is easy because of an interactive processing mechanism that leads to the alignment of linguistic representations between partners. Interactive alignment occurs via ...

Image quality assessment is a complex problem due to subjective nature of human visual perception. One of possible ways to take into consideration user’s subjectivism is to develop interactive system which could learn the properties of user’s visual perception. In this paper we present a novel way to do this via interactive neuroevolution approach. The key feature of this approach is training o...

Experimental evaluations dealing with visual known-item search tasks, where real users look for previously observed and memorized scenes in a given video collection, represent challenging methodological problem. Playing searched “known” scene to prior the task start may not be sufficient terms of memorization re-identification (i.e., need necessarily successfully “implanted”). On other hand, en...

This paper charts the design and build of two interactive tabletops that use infrared (IR) illumination techniques. One table implements fiducial tracking, whilst the other implements multitouch tracking. Trade-offs in both designs are discussed to highlight key considerations when building an interactive table. Using three key dimensions from lessons learned, we conduct a comparative analysis ...

of the physical target location, implying that the mean perceived target location is nearly coincident wi th the targe t. Thjs find ing means that perceived egocentric distance is quite accurate under full cues for the range of distallces studied. When visual cues to rustance are diminish ed , observers make systematic errors in their visually directed responding. When the target is closer than...
