Key research themes
1. How can asynchronous multimedia communication reconcile the benefits of full non-verbal cue availability with the flexibility of store-and-forward messaging?
This research area investigates the design and implementation of asynchronous audio/video group conferencing systems that aim to merge the fidelity of synchronous multimedia interaction, characterized by full visual and auditory non-verbal cues, with the convenience and flexibility offered by asynchronous communication modes. It addresses challenges in indexing, storage, and retrieval of rich media content to enable non-linear access and how such systems impact users' satisfaction, affective connection, co-presence, and task effectiveness, especially in distributed and time-shifted communication settings.
Key finding: Describes the development of a hybrid asynchronous audio/video conferencing system allowing users to capture, store, index, and retrieve audiovisual messages non-linearly by order, topic, or participant subsets. The study... Read more

3. How can multimedia technology enhance language learning and educational engagement through interactive, multimodal content delivery?
This area explores the design and evaluation of multimedia-based educational applications that leverage interactive storybooks, multimedia elements (audio, video, images, text), and multimodal presentations to improve language proficiency and learner engagement. It considers the integration of instructional design models and rapid prototyping to develop digital learning environments that foster literacy and comprehension, especially in early childhood and second language acquisition contexts.
Key finding: Reports the design and development of an interactive storybook application incorporating carefully selected multimedia elements to encourage reading and improve English language proficiency among children aged 6–8. Using... Read more
Key finding: This complementary study corroborates the utility of combining multimedia elements (audio, images, animation) in interactive storybooks tailored for language learners, reporting improvements in reading motivation and... Read more
Key finding: Advocates for distributed multimedia learning environments (DMLE) that integrate interactive multimedia technologies with telecommunications for enriched educational experiences. The paper outlines a communication-centered... Read more
