So I've seen that the Moto x has the Touch less Control that allows the user to have the option to use their phone without even touching it. Little did I know that the same could be done with my Nexus 5. Just head to the Settings on the Google Now page at the bottom, then tap on "voice". From there, tap "OK Google detection". Afterwards you just have to train your voice 3 times and can now have the ability to activate Google now fro. Anywhere, including while the phone is sleeping, if you check the lock screen activation box. From there, you should now be able to use Google now from the lock screen without having to press the power button or from any application throughout your Nexus 5 or device that is running the Google Now Launcher.
