The term 'multimodal interactions' (MMI) on the HCI field refers to the situation where a system offers many ways of interaction. This talk combines an academic subject with the daily JS we already know. It is an effort to bring together two, at first, different worlds looking for a win-win situation. On the one hand, academia could enjoy getting a novel approach to a particular problem thanks to our awesome JS. On the other, the industry can get new ways of interaction which can be applied on a variety of context and/or products. In short, the talk contains: - A quick introduction to MMI (Multimodal Interactions) - A particular novel approach to add support for MMI on Web Apps. - Short list of related open problems or possible research lines to pursuit.
