Why the Nexus 5 should advance touchless control

The Android-gossip consensus is that we'll see a Nexus 5 running Android 4.4 KitKat revealed on Tuesday, yet we've heard of no confirmation or official invites to any unveiling. Whether the big debut of the next pure Google phone has been pushed back or not, there's one killer feature I expect to see in the next Nexus that hasn't been directly addressed by the multitude of leaks -- the touchless control capability we've already come to know through Motorola's Moto X and latest Droids. Voice control assistants like Google Now and Apple's Siri didn't revolutionize our relationships with our devices and the wider digital world overnight, but Google continues to play the long game on the concept. With touchless control, Motorola and Google upped the ante in the quest for that holy grail of Silicon Valley buzzwords that means nothing to most normal humans -- frictionless user interaction.
