A Novel Approach of Human Hunger Detection especially for physically challenged people

The key intention is to communicate using thoughts of brain without using any muscle control especially for severely paralyzed people and going through an non-invasive approach for less complexity and more easy to do job. Here with the help of a single electrode, single channel, BCI interface with respect to a Bluetooth device is placed on a band which in turn paired with PC for tracking and monitoring the brain signals when placed on the scalp of a person to detect human hunger, thirst and rest-room sensations with the help of images placed in front the person for a defined period of time effectively through brain computer interface. This final result can be obtained by analyzing attention level of the person. The attention levels of each image is compared with its corresponding image in MATLAB and resulted value of attention level is obtained and further can be conveyed by voice response system.
