Google I/O is a big event for the world, especially to those who expect the company to launch the much awaited Android Wear.

Google is set to unveil the full Android Wear SDK, giving out details on Android Wear hardware pricing and its availability and share details with developers so that they can start working on different apps. Before the details are shared, sources like techradar and PCWorld directs more on Android Wear.

Android Wear

Android Wear sends out all the Google Now alerts and other notifications to the smartwatch that is worn on the wrist. It includes the system called "context stream," which knows the location and time of the day and it appears on the wrist as useful data.

The data is designed and will automatically appear even before it is needed. Like Android phones, Android Wear can also automatically push weather alerts, sports scores, travel itinerary updates, and all the other card-based data points via Google Now. It also supports the smartphone notifications by taking action directly from the Android Wear watch if any phone call or text message is received. These watches will also include a microphone to dictate a reply of a text through the use of voice recognition.

Okay Google

Unlike other smartwatches, Android Wear watches would be running apps as cards that sweep on and off from the homescreen due to the external signal or by a user voice command "Okay Google". Even when the user is busy with the schedule or he is at an unknown place with the help of "Okay Google," he can find out the score of a match and find out the best restaurants nearby. The PCWorld reported the Android Wear is designed to be "simple, glanceable and built on micro-interactions."

Navigation

To keep it simple, Google uses "stacks" and "pages" for its navigation schemes. If there are multiple notifications from a particular app then these are collected together in a single "stack" of cards. If there is a lengthy notification, it is broken into series of "pages."

Third-party Apps

Google invites developers to improve the user's experience instead of including new apps. The company adds "just a few lines of code" so that developers update stacks, pages and notification replies. Also, by using the full SDK developers would be able to modify services for a more rough Android Wear experience.
