Main research

Hypermedia and Electronic Publishing

Through innovations in digital typography and electronic publishing, computers enable new styles of reading. Audio and music, animation, video, multimedia, hypermedia, and live documents extend traditional literacy. Enhanced capabilities include character articulation, word-sized graphs and images, textual animation, spatial browsing, stereographic display, complementary multimedia, dynamic interaction, and duplex reading. A document can be considered a database, through which almost arbitrary slices can be made, reprojecting contents according to reader initiative.

Mobile-Ambient Mixed Virtuality Systems

Ambient media refers to a space's expressive channels, typically driven through fixed-location, public display equipment, such as computer screens, projection systems, stereo speakers, loudspeaker arrays, etc. Mobile media, in contrast, is portable but basically personal. "Mobile ambient" applications integrate these interaction styles, featuring cross-scale interactivity that exploits both personal mobile devices and location-based public displays. For particular instance, sensors on smartphones and tablets can measure orientation, which data can modulate ambient displays, including whirling of panoramic and turnoramic images and spatial sound, as well as avatar or rigged model attributes in augmented virtuality or mixed reality scenes.

Modelling and 3D Printing of Intelligent Shapes

3D Kanji is a 3D symbol for the future society that enhances current flat characters and symbols. Using unique techniques and algorithms, characters can be transformed into completely new sophisticated, intriguing 3D shapes that still resembles the original characters. We are exploring various applications of this family of new 3D symbols, especially new methods to embed more data/knowledge into the form, modelling technologies, 3D printing technologies and identification methods.
