With the increasing popularity of [[smartphones]], the general public are becoming more comfortable with the more complex modalities. Speech recognition was a major selling point of the [[iPhone 4S]] and following [[Apple Inc.|Apple]] products, with the introduction of [[Sirius|Siri]].<ref>{{Cite news|url = http://bgr.com/2011/11/02/siri-said-to-be-driving-force-behind-huge-iphone-4s-sales/|title = Siri said to be driving force behind huge iPhone 4S sales|last = Epstein|first = Zach|date = Nov 2, 2011|work = |access-date = April 21, 2015|via = }}</ref> This techologytechnology gives users an alternative way to communicate with computers when typing is less desirable.

==Using Multiple Modalities==

Having multiple modalities in a system gives more [[affordance]] to users and can contribute to a more robust system. Having more also allows for greater [[accessibility]] for users who work more effectively with certain modalities. Multiple modalities can be used as backup when certain forms of communication are not possible. This is especially true in the case of redundant modalities in which two or more modalities are used to communicate the same information. Certain combinations of modalities can add to the expression of a computer-human or human-computer interaction because the modalities each may be more effective at expressing one form or aspect of information than others.

There are six types of cooperation between modalities, and they help define how a combination or fusion of modalities work together to convey information more effectively.<ref>{{Cite book|title = Multimodal Human Computer Interaction and Pervasive Services|last = Grifoni|first = Patrizia|publisher = IGI Global|year = 2009|isbn = 9781605663876|___location = |pages = 37|url = https://books.google.com/books?id=O8CqMtIKSWwC&source=gbs_navlinks_s}}</ref>
