Enhancing World Wide Web developments, the new opportunities for interactivity and flexible access to various media challenge the traditional experience in shaping learning environments for online education. The major difficulties are related to the appropriate development of learning environments in order to achieve a final design, which improves the motivation and the result, and serves the c...

Supporting human-robot interaction (HRI) in dynamic, multi-party social settings relies on a number of input and output modalities for visual human tracking, language processing, high-level reasoning, robot control, etc. Capturing visual human-centered information is a fundamental input source in HRI for effective and successful interaction. The current paper deals with visual processing in dyn...

This paper reports a case study on how a conceptual and analytical thinking approach was used in Art and Design Department at Multimedia University (Malaysia) in addressing the issues of one nation and its impact in the society through artworks. The art project was designed for students to increase the know-how and develop creative thinking in design and communication. Goals of the design proje...

Executions of modern parallel programs often yield complex communications among compute nodes of large-scale clusters of workstations or supercomputers. Analyzing communication patterns is becoming increasingly critical to performance optimization. As the scale and complexity of parallel applications drastically increases, visu-alization has become a feasible means to conduct analysis of massiv...

In crisis situations, decision-making capabilities rely on reports from all parties involved. For achieving the necessary capabilities of crisis technology, a communication-interface prototype representing concepts and ideas has been developed. To support language-independent communication and to reduce the ambiguity and multitude of semantic interpretation of human observers’ reports, the mess...

In this paper, we review recent research that examines audio-visual integration in multimodal communication. The topics include bimodality in human speech, human and automated lip-reading, facial animation, lip synchronization, joint audio-video coding, and bimodal speaker verification. We also study the enabling technologies for these research topics, including automatic facial feature trackin...

A novel scheme for visual communication by means of mobile devices with limited colour display capability is proposed. A colour quantization technique is first proposed based on the perception of human visual system on skin colour. An efficient coding scheme is then developed to compress colour quantised video at very low bit rate.

Although private communication is considered an important diversifying force in evolution, there is little direct behavioural evidence to support this notion. Here, we show that ultraviolet (UV) signalling in northern swordtails (Xiphophorus) affords a channel for communication that is not accessible to their major predator, Astyanax mexicanus, the Mexican tetra. Laboratory and field behavioura...

Ram R. Rao Georgia Institute of Technology Atlanta, GA 30332 [email protected] Tsuhan Chen AT&T Bell Laboratories Holmdel, NJ 07733 [email protected] ABSTRACT In this paper, we present a novel means for predicting the shape of a person's mouth from the corresponding speech signal and explore applications of this prediction to video coding. The prediction is accomplished by modeling the ...
