Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data

Augmented reality applications can enhance a user's experience when traveling by providing real time informational displays regarding a location and its features

The amount data we rely on every day is overwhelming, and there is no sign of it slowing down. Instead of having users find the information they need, the information should come to them automatically

Battery issue is one of the major concern of android devices, as our application is having social features so application require to remain active every time, which drains battery

The major concern of our project to avoid drainage of android device battery, because our application contains many social features and for that user have to active with internet service.

Other concern is not make our application as light as possible. If application is heavy it hang the phone.

We use PUSH notification features which will work even though our application is closed by sending deals as a notification.

We use multithreading and put our database used in our application online.

It is an application which tells you nothing on a literal or intellectual level, but which in instinctive, emotional terms makes you understand more than you will ever be able to verbally communicate to another human being

We use our own “Software Sensor”.

Eclipse is an Integrated development environment (IDE). It contains a base workspace and an extensible plug-in system for customizing the environment. Written mostly in Java, Eclipse can be used to develop applications in Java

Eclipse uses plug-ins to provide all the functionality within and on top of the runtime system. Its runtime system is based on Equinox, an implementation of the OSGi core framework specification

Android Studio is an integrated development environment (IDE) for the Android platform Android Studio includes a powerful code editor. It's based on the IntelliJ IDEA editor, which supports features such as smart editing, advanced code refactoring, and deep static code analysis

Hardware Requirement:

Processor: ARM(armebai-v7a) and above

RAM: 512 Mb

Disk space: Min. 1Gb

Device GPS

Software Requirement:

For developing the application:

Operating System: Windows 7/8

Language: JAVA, XML, php, MySQL

Tools: Android (IDE)

Debugger: Android Dalvik Debug Monitor Service

For running the application:

OS: Android 2.2 or higher version

Low Pass filter Algorithm

The Android sensor framework lets you access many types of sensors. Two very basic types are:

1. Hardware Sensors.

2. Software Sensors.

Hardware sensors are physical components built into a handset or tablet device. They derive their data by directly measuring specific environmental properties, such as acceleration, geomagnetic field strength, or angular change. For example: Sensor.TYPE_ACCELEROMETER", Sensor.TYPE_MAGNETIC_FIELD

Software sensors are not physical devices, although they mimic hardware-based sensors. Software-based sensors derive their data from one or more of the hardware-based sensors and are sometimes called virtual sensors or synthetic sensors. For example: Sensor.TYPE_ORIENTATION, Sensor.TYPE_ROTATION_VECTOR

Our application is reliable but it’s not 100% accurate and can produce still more accurate results if we use gyro sensors. However we have applied low pass filter to improve the accuracy of our application.

Compass tends to go crazy near magnetic devices.

Markers overlap each other to resolve this problem we can use better plotting system.

By combining the accelerometer sensor and magnetic sensor and by applying low pass filter we can get orientation of device. Fix location can be calculated using GPS and with the help of latitude and longitude we can receive the nearby data of selected categories

Rather than using polling Pushing is better because it saves battery whenever our server has data to send to all application it can send that data to all devices.
