There are some details that alter the results, such as change in temperature, but the device is quite workable. The article says that it has been in the works for over a year, but it was finally presented at a conference in Spain just last month. Though it may not become a commercial device anytime soon, there are so many possibilities that could come with it. In the future, researchers hope to add smell and texture so you get the full experience of whatever you're doing.
My favorite possibility, though, is the thought of being in a movie and being able to taste and smell what the actor "supposedly it" as well. Though there are many bad possibilities that could come of this as well, we'd never watch movies the same way again. If this were to happen, though, people may not go because it's likely the prices would go up too much.
The last thing the article talks about is incorporating this into video games. It's really quite interesting because it discusses going on a reward system. For example, if the player were to beat a level, they would be rewarded with sweet tastes, but if they fail, a bitter or sour taste.
I like this idea, although I don't find it to be necessary in any way. We are already filled to the brim with new technology, but the fact that this is even possible makes it seem worth it. I can't wait for the day when I can go see a movie and be able to watch, feel, taste and smell what's going on. Does it seem a bit much? Maybe. Too soon? Never.
