Scientists are exploring the brain's ability to process different sensory stimuli as visual input, thus allowing, for instance, blind people to navigate through space. Eye Candy is a metaphor for the brain's extraordinary plasticity—its potential to create new synapses and adapt to sensory input, to substitute one sense for another, and to use a variety of information sources to augment an experience of the world. This sensory plasticity may eventually make science fiction scenarios a reality: internal positioning systems, subconscious communication between people over long distances, touch that we can see, and sweets that trigger visual explosions in our minds. Electrodes on the surface of Eye Candy transmit visual information (uploaded to the device via USB) through the tongue to the brain at the same frequency as the eyes send visual information. The mind decodes the taste of the sweet candy as vivid pictures.
