HTML5 has paved the way for development of rich web applications and has been widely adopted by application developers. Ease of user-interaction (user experience) with applications has become a prime focus world-wide, thanks to the proliferation of new devices and platforms including mobile phones, tablet devices, eBook readers, and gaming platforms. In addition, traditional platforms such as TV's, sudio systems, and automobiles are rapidly becoming capable of much more intelligent interaction than in the past. User-interaction through speech, touch, gesture and swipe has become the key differentiator in the success of popular applications today. One of the key advantages of the W3C Multimodal Architecture (MMI) is its suitability for simple to sophisticated applications across devices in creating compelling user experiences, leveraging advances in i/o methodologies, and supporting inter-operability among multiple vendors' products.
