IBM has made a prediction that in just 5 years cognitive computers will be able to see, hear, taste, touch and smell. Bernard Meyerson, Chief Innovation Officer at IBM says, "This year, we focused the IBM Next 5 in 5, our 2012 forecast of inventions that will change your world in the next five years, on how computers will mimic the senses:
Touch: You will be able to reach out and touch through your phone
Sight: A pixel will be worth a thousand words
Hearing: Computers will hear what matters
Taste: Digital taste buds will help you to eat healthier
Smell: Computers will have a sense of smell"
It's all described in this video below.
Incidentally, I've always been puzzled by the "5 senses" as I've always thought I have 6 senses - motion being the 6th. The awareness of being up or down, accelerating or decelerating moving forwards, left or right. To me that's a "sense," distinct from the other 5, but just as useful.
