Location-Aware Emergency Button for Blind Stick Navigator
International Journal of Advanced Trends in Computer Science and Engineering · 2020
Blind and visually impaired people require assistance in their movement.They normally walk using a stick to preserve the sense of direction.In emergencies, they have difficulties in asking for help or contacting their guardians and they have to depend on the people around them.Therefore, this project proposes to build a blink stick with an emergency response button that uses current technologies such as GPS, GSM, and Bluetooth to connect them to their guardians.Once they activate the emergency button, an SOS message with a link to the user's location is sent to the guardian, enabling them to respond to the SOS.Thus, the response time to the SOS message is crucial to ensure the distressed person receives help without undue delay.Most research on the blind stick is focused on navigation and seldom addresses the issue of response time to the emergency signal.Therefore, this study evaluates the response time of different service providers to the SOS messages to see how long it would take from the time it is activated from the blind stick to the time it reaches the guardians and caretakers of the blind.The analysis findings have led to recommending for the blind people suitable network service providers based on a selection technique.This research output can also be extended to people who are likely to face emergencies, such as heart attack, sudden hypertension, and diabetic coma.
