There are currently door “bells” for the deaf. They usually have a light that flashes brightly instead of playing a tune. Unfortunately, many deaf people are also blind due to the same genetic problems that cause their deafness. It is almost 25 percent in fact. I plan to make a device which, when activated, uses the only reliable sense left - other than smell and taste - touch. This could incorporate a vibrating motor in the person’s pocket.
