How Tech Can Help the Visually Impaired

I grew up with a blind grandmother, who lost her vision to glaucoma. The medicine of the 1930's and 1940's, unfortunately, couldn't prevent that fate. So from a very early age I was acquainted with someone with a serious disability. By the time I was three years old, I was part of the caretaker crew, often leading her around the house as we navigated various obstacles. One time, my aunt blindfolded me and made me walk around the house, so that I might better understand my grandmother's life.
