objectives: instruction of local anesthesia injection in an important part of dental education curricula. this study was performed to compare dental students’ preference with regard to tactile or visual determination of injection site for an inferior alveolar nerve block (ianb) in children. materials and methods: this crossover randomized clinical trial was conducted on dental students of zahed...

Technical use of visual information in human machine dialog management presupposes a use of visual cues by humans. The current study tries to determine to what extent human subjects can use visual cues to detect Transition Relevance Places (TRPs) in prerecorded and annotated continuous dialogs. Subjects were asked to utter minimal responses to dialog recordings that were presented Audio-Visuall...

Despite the abundance of research on teachers’ repair practices in language classroom interaction, there are not enough conversation analytic studies on repair organization with the focus on the details of interaction in the context of EFL. Drawing on sociocultural and situated learning theories, this study explores the contingent nature of English language teachers’ org...

Based on theoretical findings from the literature integration of reading and writing pedagogies used with hearing postsecondary students to advance academic literacy, this article offers a model instruction for achieving literacy in developmental freshman composition courses composed deaf students. Academic is viewed as product acts composing which best transpire through reciprocal rather than ...

Cantmlling mbot behaviors becomes more important recently as active perception for mbot, in particular active audition in addition to active vision, has made remarkable progress. We are studying how to ereale social humanoids that perform actions empowered by real-time audio-visual tracking of multiple talkers. In this paper, we present personality as a means ofcontmlling non-verbal behaviors. ...

We are studying how to create social physical agents, i.e., humanoids, that perform actions empowered by real-time audio-visual tracking of multiple talkers. Social skills require complex perceptual and motor capabilities as well as communicating ones. It is critical to identify primary features in designing building blocks for social skills, because performance of social interaction is usually...

This work presents a novel approach to speech enhancement by exploiting the bimodality of speech and the correlation that exists between audio and visual speech features. For speech enhancement, a visually-derived Wiener filter is developed. This obtains clean speech statistics from visual features by modelling their joint density and making a maximum a posteriori estimate of clean audio from v...

Blindfolded participants were guided along routes from two display modes: spatial language ("left," "right," or "straight") or spatialized audio (where the perceived sound location indicates the target direction). Half of the route guidance trials were run concurrently with a secondary vibrotactile N-back task. To assess cognitive map development, subjects performed a homing task from the route...
