The majority of augmented reality
applications these days may be visual ones, but that's hardly the only type of augmented reality possible, as fully evidenced by this so-called TagCandy device built by Yasuaki Kakehi of Keio University. As you can see above, it consists of a rather large base that accommodates a regular lollipop, which not only makes it easy to hold the candy, but uses bone-conduction technology
to produce different sounds ranging from fizzy soda to fireworks. Of course, it is just a concept, and still something of a work in progress -- future possibilities apparently include the ability to detect biting in addition to sucking, and the ability to buy and share different "sensations" on the internet. Head on past the break to check it out on video.
