 The main objective of this project is to reduce the difficulties faced by blind
 people and provide ease accessibility to them by guiding to their designated place
 inside a territory through the suggested system as a solution to navigate indoor

+environment without others interaction.
+
+**Research Question:**
+
+In modern world, there are lot of outdoor navigating systems, so there are few of
+those can be applicable for indoor due to poor GPS signaling inside the buildings,
+among them for the blind impaired people have to face more challenges to use them.
+Main concern in authors proposed research project,” is how this indoor navigation
+system is applicable for blind impaired people?”. According to the WHO there are over
+385 million people in the world, are spurring vision impairment hence this proposed
+title is significant for the vision impaired and blind community
+
+•	Main issue is navigating inside buildings and public spaces full of
+unfamiliar features is too difficult to attempt the first time for a number
+of reasons, reducing their confidence in independent navigation for visual impeded people.
+
+•	Another issue is, when blind impaired people met people, obstacles
+on their way they face many difficulties. It’s hard to identify each other.
+
+**Individiual Component:**
+
+**IT18180930:**
+Localization
+
+Through the inputs such as sensors, images, videos get the exact location and
+store the inside the real time databased with labeling information to provide
+rightful information about indoor location. Use Simultaneous Localization And
+Mapping (Visual SLAM) to create map of the environment to the system. 
+
+**IT18072334:**
+Location of the obstacles and obstacle detection
+
+Identify obstacles, categorize obstacles such as moving obstacles (Tables cupboard.)
+fixed obstacles and their coordinates to identify its location inside the spatial
+environment in the root when user navigating to the location.
+
+**IT18374452**
+Data transaction and Security
+
+Implement or modify lightweight protocol to send and receive data. Because data
+retrieval and submission should be happened quickly to get navigation information.
+Send and receive overhead of the protocol delayed the process. Hence lightweight
+protocol smoothens the communication channel. Add security methods for algorithms
+and send receive protocols to maintain trust relationships to maintain data assurance.
+
+**IT18075618**
+
+Handle real time database to store data schema design, optimization methods to store
+spatial environment data that can be facilitate crate indoor map as well as voice map.
+Developing mobile app that available for both android and iOS devices. Correction of
+path in case of misdirection
