An Android-based Portable Smart Cane for Visually Impaired People

In today's encouraging world of technology, mobile applications are a speedily increasing segment of the worldwide mobile market. An android operating system is the highest accepted and extremely developing open platform for mobile application development. Due to the rise of the impaired people population and there are limited technological-based facilities, we want to leverage technology to develop an Information & Communication Technologies (ICT) based smart portable cane for visually impaired people using android application. We have created an information-based probabilistic relative model amongst the key indicators and sequenced their data gathering priority and precedence. The device is developed and tested with blind people that gives better results for reliability, user friendly, portability, less weight, and economical so that everyone can easily purchase, mount, and configure to walk more confidently and perform a necessary operation such as obstacle detection in the range of 5 feet with varying buzzer frequency after every 12 inches to give batter understanding of distance to obstacle also the facility to operate mobile from the mounted device such as sending a message to caretakers, dialing a call, help message, SMS read and open Google maps to navigate by a single click on the mounted buttons on a white cane that wirelessly communicates through Bluetooth transceiver.
