107. Design an alarm clock for a blind person
Question:
Design an alarm clock for a blind person
maybe an answer:
There are 5 senses: sound, vision, touch, smell, taste
Vision is ruled out because the person is blind.
So the alarm clock needs to stimulate one of the other senses. A smell or taste based clock would not be very practical. So a regular alarm clock that makes noise or vibrates would be suitable.
A variation of this question is to design an alarm clock for a deaf person, in which case a vibration based clock might be suitable.
