the present research identified major barriers of isfahan university teachers participation in electronic technology courses. a second goal of this study was to examine the effects of characteristics and demographics of university teachers on these barriers. in this research problems and barriers fell into three distinct categories: personal, perceptual, and contextual. a questionnaire was desi...

traditional and modern vocabulary instruction techniques have been introduced in the past few decades to improve the learners’ performance in reading comprehension. semantic mapping, which entails drawing learners’ attention to the interrelationships among lexical items through graphic organizers, is claimed to enhance vocabulary learning significantly. however, whether this technique suits all...

CHIL ("Computers in the Human Interaction Loop") is an Integrated Project under the European Commission's Sixth Framework Programme. The CHIL consortium is jointly coordinated by Universität Karlsruhe (TH) and the Fraunhofer Institute IITB. CHIL was launched on January 1st, 2004. The objective of this project is to explore and create environments in which computers serve humans who focus on int...

In this article, a formal approach for modeling central concepts of context-awareness in ubiquitous and mobile computing is introduced. The focus is on an appropriate handling of issues of vagueness and granularity in ubiquitous computing environments. A formalization of perceptual and sensory uncertainty and a characterization of granularity are applied for modeling three central aspects of co...

In this paper, we present our egocentric interaction model for recognizing and supporting everyday human activities. We explain how it allows designers of ubiquitous computing systems to view physical (real) and virtual (digital) objects as residing in one single space and how sets of objects in the vicinity of a specific human actor can be classified based on human perceptual characteristics s...

A robust method of intelligent information processing with respect to user’s perception of data, named Perceptual Information Processing (PIP), is being studied. This method uses fuzzy sets as the representation of user perceptions and a soft computing method called Mass Assignment Theory (MAT) the computational core to manage consistencies between histograms of actual data and the fuzzy sets. ...
