There are hundreds or even thousands of people in our country and in the world who have
problems in terms of health. There have been inventions aimed at facilitating the lives of
healthy people, who are generally in the majority, but are often lacking or completely useless
for the use of people with health problems. For example, glasses is a great invention for
someone with eye problems, but for someone who does not have glasses, it may be difficult to
wear glasses, but with a simple lane, this work is solved.
Traffic lights regulate transitions to prevent people from being injured, but they have no
meaning for someone who is not able to see, but they are resolved when an audible warning is
added to the traffic lights, or even more simply, it doesn't make sense for the visually
impaired, but simply by using the relief method, this problem has been solved. I started
researching these subjects for the construction of a device to help people with hearing
problems like a doorbell.
