He was awarded the Hitachi Fellowship 2003, the A-STAR Young Scientist of the Year Award 2003, and the SCS Singapore Young Professional of the Year Award 2004. In 2004 he was invited to be the Singapore representative of the United Nations body IFIP SG 16 on Entertainment Computing and the founding and present Chairman of the Singapore Computer Society Special Interest Group on Entertainment Computing. Also in 2004, he was awarded an Associate of the Arts award by the Minister for Information, Communications and the Arts, Singapore.
Owen Noel Newton Fernando is a Research Fellow in the Mixed Reality Lab. at the National University of Singapore. He received his B.Sc. in Computer Science from the University of Colombo, Sri Lanka, and M.Sc. & Ph.D. in Computer Science and Engineering from the University of Aizu, Japan. He has previously worked at the Peoples Bank (leading government bank in Sri Lanaka) IT department as a Systems Analyst. He was awarded the Japanese Government (Monbukagakusho: MEXT) scholarship in 2004. Fernando is the author or coauthor of five Journals and fifteen conference publications.
Professor Michael Cohen is Professor of Computer Arts at the University of Aizu in Japan, where he heads the Spatial Media Group, teaching information theory, audio interfaces, computer music, and researching interactive multimedia, including virtual & mixed reality, computer music, spatial audio & stereotelephony, stereography, ubicomp, and mobile computing. He received an Sc.B. in EE from Brown University (Providence, Rhode Island), M.S. in CS from the University of Washington (Seattle), and Ph.D. in EECS from Northwestern University (Evanston, Illinois). He is the co-developer of the Sonic (sonic.u-aizu.ac.jp) online audio courseware, the author or coauthor of over one hundred publications, four book chapters, and two patents, and the inventor or co-inventor of multipresence (virtual cloning algorithm), the Schaire, nearphones, SQTVR, and Zebrackets.
Narrowcasting and selection functions
Narrowcasting and selection functions can be formalized in predicate calculus notation, where ‘¬’ means “not,” ‘^’ means conjunction (logical “and”), ‘’ means “there exists,” and ‘’ means “implies.” The general expression of inclusive selection isactive(media processor x) = ¬ exclude(x) ^ ( y (include(y) ^ self(x) = = self(y)) include(x) )So, for mute and select (solo), the relation is active(source x) = ¬ mute(x) ^ ( y (select(y) ^ self(x) = = self(y)) select(x) )mute explicitly turning off a source, and select disabling the collocated (same room/window) complement of the selection (in the spirit of “anything not mandatory is forbidden”). For deafen and attend, the relation is active(sink x) = ¬ deafen(x) ^ ( y (attend(y) ^ self(x) = = self(y)) attend(x) )
