A m-Health Based Mobility Aid For Visually Challenged Persons

God's greatest wonderful gift to humanity is the ability to perceive and interact with the world around them. However, some people have lost this skill owing to accidents or congenital illnesses. In this high-tech era, numerous assistive devices are on the market to aid people with impairments in living independent life. However, most existing medical assistive devices are not widely accepted due to their expensive cost, laborious setup involving high-end electronic components, and discomfort. So, to address this issue in existing medical devices, we developed a cost-effective medical assistive device in the form of a shoe that can be accepted by anyone who is blind and allows them to live an independent life without relying on others. This device is made up of an ultrasonic sensor and a camera that detects obstructions and sends signals to the user through a voice assistant. A flame sensor detects the presence of fire within and around the user. An IR sensor is used to identify pits. This infrared sensor will assist the vision impaired in protecting themselves from falling into the pit. In addition, an accelerometer sensor is utilized to aid the ultrasonic sensor in alerting the user to impediments while walking alone, rather than while sleeping or sitting in the same posture for an extended length of time. All sensor output is indicated to visually impaired people via a buzzer, and messages are delivered to the caregiver via IoT. To reduce power usage and make use of existing natural resources, we are deploying solar panels that generate electricity from the sun, which is a renewable resource. We designed it to be water-resistant for product purposes. This low-cost medical assistive gadget allows visually impaired people in the community to live a free and independent life rather than relying on others. Thus, this effort is a stride forward taken for the betterment of visually impaired individuals and to change their lifestyle.
