Recently, I saw from the news that such a story of entrepreneurship is both moving and inspiring. It is said that a female entrepreneur from Bulgaria sees the society as unfriendly to the blind, so she puts in the innovation of combining software and hardware. Technology, invented the tablet for the blind.
You should know that there are 285 million people with vision loss or blindness in the world. Their IQ and ability are not lost to the average person. This market is already very big, and doing this is a good thing to serve the society and make money! It is said that Apple is also very optimistic about this field, which is clearly a new blue ocean!
