Multimodal and Multichannel Issues in Pervasive and Ubiquitous Computing

For the general public, the year 1984 marks the emergence of WIMP (Windows, Icon, Menu, Pointing device) interfaces. Developed at Xerox PARC in 1973 and popularized by the Macintosh, this type of graphical user interfaces is still largely used today, on most computers. However, in recent years, numerous scientific researches focus on post-WIMP interfaces. It is no longer limited to a single way of interacting with a computer system, but considering the different solutions to offer user interfaces as natural as possible. With the introduction of many types of mobile devices, such as cellphones, Personal Digital Assistant (PDA), pocket PC, and the rise of their capabilities (Wifi, GPS, RFID, NFC...) designing and deploying mobile interactive software that optimize the human-computer interaction has become a fundamental challenge. Modern terminals are natively equipped with many input and output resources needed for multimodal interactions, such AbsTRACT
