to activate touchless search
"Okay Google." Those Touchless Controls aren't just for the Moto X anymore -- they're now part and parcel of the Nexus 5. With today's unveiling of Google's (terribly leaked) Nexus 5, we're getting a first look at Android 4.4 KitKat on the handset, and that OS update comes with some significant tweaks to Search and Now. For starters, Nexus 5 users will have the ability to set hot keywords as a means of activating or "waking up" Now voice search. So, presumably, this means you'll be able to link any word you'd like to start barking voice commands at Now.
Just don't be surprised if Now talks back to you: KitKat also apparently allows for a dialogue of sorts between users and the handset to refine search queries. This could be especially useful when directing Now to access contacts by first name. For example, saying "Text Jennifer" could result in it asking you to specify, "Which Jennifer?" It's smart control made smarter.
Google Unveils New Nexus 5 phone
New Nexus 5 smartphone from Google starts at $349
for an unlocked 16GB version
SAN FRANCISCO — Google unveiled its new Nexus 5 smartphone Thursday as the Internet search giant steps up competition with Apple's iPhone, especially in emerging markets.
The device has a 5-inch display and is tightly integrated with new Google search capabilities and Google Now, the company's personal-assistant technology, through the home screen. It went on sale Thursday.
Nexus 5, which Google developed with LG, comes with a new camera that corrects for small hand movements to reduce blur. New camera software also helps users take better photos in difficult situations, such as low light with fast-moving subjects.
The device comes in black and white and costs $349 for a 16GB unlocked version or $399 for 32GB. That's cheaper than Apple's new iPhones. The iPhone 5c, the cheaper of the two new iPhones, costs $549 for a 16GB version that comes without a wireless contract.
