Android Context Awareness in ActionHow it works: A simple example by the Android Wear design

guidelines4

Build an AppFor this example, you build a social

app for restaurants.

App Recognizes UserWhen a user is by a restaurant, the app uses location data to trigger

restaurant context.

Content is PushedThe app recommends popular menu

items as content that is relevant to the user in a specific space-time frame.

SEARCHES

ACTIVITY TRACKING

LOCATION

Google Now

Google Now is an app by Google that comes embedded into the most

recent Android versions.

It provides relevant information to users thanks to a learning process

based on different sets of data, such as…

WHAT GOOGLE NOW DOES WITH CONTENT, CAN BE DONE WITH WITH SENSORS AND SMART NOTIFICATIONS TO SHAKE UP THE

USER EXPERIENCE

A Practical Use Case of Android Context Awareness in Action As defined by the Android Wear design guidelines4

“By using device sensors and other contextual cues,

your app can reveal information and functionality

precisely when the user needs it, at a

glance.”

IF DOIF/DO LogicOn a user experience level, we

decided to communicate in full transparency the IF/DO logic of

rules that the android context aware engine relies on.

On one hand we have a series of sensors that enables the context

aware device to sense the real world. This covers the “IF” part of the

logical process.

On the other hand, we have the rule engine which is always listening for

specific inputs to trigger corresponding actions, based on the perception of the context. This covers the “DO” part of

the process.

Listen, Learn, Predict, Suggest This is our way of delivering android context awareness.

Gather user data that is received by the

sensors over a certain span of time.

ListenLearn through analysis, profiling, and clustering

the data stream.

LearnUse the learned data to

predict IF/DO rules based on context.

PredictThe system can adjust

the IF/DO rules and make them more

dynamic, adapting to the real life context of

the end user.
