Google Now is a new search feature the company introduced that allows users to search with results based on location, calendar and search history. It is designed to get the user "...the right information at just the right time," said Hugo Barra, director of product management.
For example, if you search for a type of restaurant, search results will appear based on restaurants based on location, and the feature will also let you make a reservation from the results.
Google Now also uses calendar events to get the user the most helpful information, reminding users of appointments and showing users the best way to get to their appointment based on their current location.
