| Summary: | The measures put in place to stop the spread of the coronavirus have created a slew of problems
for the visually impaired. One significant challenge is the need to keep a safe distance of one
metre from others. For the visually challenged, this is a challenging task because they are
unable to detect whether others are close to them, let alone determine whether they are standing
one metre away.
The purpose of this study is to investigate creating a wearable device that aids the visually
impaired in ensuring that there is a distance of one metre between them and others. The device
must be able to alert the user when someone is within a one-metre radius, as well as be able to
function for a substantial period of time on a single charge. This study compares various
physical factors of different types of sensors to determine the most suitable combination of
sensors to be used, as well as their positioning on the device.
The final design based on functionality comprises ultrasonic and thermal sensors embedded in
a belt-like framework and controlled with a microcontroller. Future work can be done to
improve on the device’s aesthetics and user experience. |
