Inspired by the abilities of both the praying mantis and the pigeon to judge distance by use of motionbased visually mediated odometry, we create miniature models for depth estimation that are similar to the head movements of these animals. We develop mathematical models of the praying mantis and pigeon visual behavior and describe our implementations and experimental environment. We investigat...

While full computer understanding of dynamic visual scenes containing several people may be currently unattainable, we propose a computationally efficient approach to determine areas of interest in such scenes. We present methods for modelling and interpretation of multi-person human behaviour in real time to control video cameras for visually mediated interaction.

This paper describes a prototype system implemented for verifying the correctness of all verb-preposition-collocations found in a given text. The verification is done using statistics from the world’s largest corpus the Internet. The tool used for obtaining these statistics is the Google Web APIs service. The probability of correctness is computed according to the concepts of proportional score...

This paper reports initial research on supporting Visually Mediated Interaction (VMI) by developing generic expression models and person-specific and generic gesture models for the control of active cameras. We investigate the recognition of both head pose and expression using simple generalisation of trained generic models using Radial Basis Function (RBF) networks. Then we go on to describe a...

This is an exploratory study investigating potential effects of emotional valence in images and their influence on conversation in the presence of the images. We used latent-semantic analysis to generalize valence ratings of Swedish words to a corpus of spoken conversations. Each utterance in the conversation was given a valence rating, which represented how emotionally positive or emotionally ...

A key feature of reactive behaviors is the ability to spatially localize a salient stimulus and act accordingly. Such sensory-motor transformations must be particularly fast and well tuned in escape behaviors, in which both the speed and accuracy of the evasive response determine whether an animal successfully avoids predation [1]. We studied the escape behavior of the fruit fly, Drosophila, an...

Drawing on the assumptions of socio-cognitive linguistics, focusing on the effective role of interaction in terms of reducing the cognitive burden in the process of learning, this quasi-experimental study aimed at investigating the effect of the Interactive Whiteboard (IWB) usage on the learning and retention of non-congruent collocations among 60 homogenized Iranian EFL learners, aged 18 to 24...
