Texting Taste

Eliza Strickland profiles Adrian David Cheok, an engineer who created a system “that would let pet owners send their lonely animals a pat during a busy workday at the office.” His next project? Taste:

Cheok has a “digital lollipop” in the works that electrically and thermally stimulates the tongue to produce basic flavors—bitter, sour, salty, sweet. He dreams of a system that would let friends in Paris send you a taste of their wine over the Internet. “The ultimate Internet,” he says, “will integrate all our senses.”
