Creating Contextual App Experiences

Creating Contextual App Experiences
User context and their interactions with the nearby world play a vital role in creating a magnificent user experience. Instant awareness of the nearby surroundings can be an amazing way to understand the users and their behaviors. The emerging new technologies like Google's Awareness and Nearby APIs, Beacons, NFC cards and WiFi signals have opened up a sea of possibilities for developing magical user experiences. This talk will encompass the importance of user context, Eddystone beacons, Google's Nearby and Awareness APIs; and examples of some of the experiences you can build with them. It will also cover ways to understand user behavior and customisation based on user actions eventually resulting in user retention.
