Look, touch and feel: How your mobile interface will morph in 2012. Touch, waving, voice all to become more prevalent mobile user interfaces: http://www.networkworld.com/news/2011/122111-outlook-mobile-interface-254225.html
I’m excited by some of these features in this article; I current use the Swype feature on my phone and love it: you don’t have to lift your finger from the keypad – you just glide from one letter to the next. It works incredibly well!
In addition to Swype, it appears that physical movements will also be seen (like Microsoft’s very cool Kinect). I do remember reading about eye tracking being difficult in some instances and even blogged about that here last December (https://euniceelsie.wordpress.com/2010/12/23/eye-movement-control-of-the-mobile-phones/). It looks like improvements have been made! Please read the linked article – the future is looking pretty exciting…
