"The age of computing has not even begun," says Stan Williams, a research scientist at Hewlett-Packard. What will be in the future in this strange world of computers? You can be made to see, hear, touch, taste, or smell anything. ...you are scared? Will be possible? The exchange of electronic information is today limited to what we can hear and see .. most computers only reproduce sound and pictures. But what about what we can smell, taste or touch? Although smell and taste are still a little way off, electronic "touch" is not far off. What do you think? will be this possible? Step by step we will stay relaxing on our chairs and smell a good stick or a good perfume, why not smell of our lover...or can touch his or she eyes? Is scaring?
