A new device to help the blind to see has been developed by scientists. The electric lollipop or BrainPort vision device captures images using a small camera and then turns the image into tiny tingles on the tongue. Tingles are sent to the brain, which then turns the tingles into pictures. After a few days of practicing people, who otherwise could not see, they were able to distinguish shapes, read signs and even read letters. This amazing new device can help people to interact with their environment so never before experiences.
Using the unique resources of the DOE's national laboratories in materials science, microfabrication, microelectrode construction, photochemistry and computer modeling, the goal of the project is to build the device capable of restoring vision with materials that will last a blind person's life. Just as blind people read words by touching Braille beats, some are now able to "see" objects through a special lollipop that stimulates their taste buds. The extraordinary device converts the images captured by a tiny camera into a series of electric tingling, which can be felt on the tongue. An electric lollipop that allows the blind to "see" with their tongue has been developed by scientists.

The machine is called a brain-port vision device and is manufactured by Wicab, a biomedical engineering firm based in Middleton, Wis. It is based on the sensory substitution, the process in which if a sense is damaged, the part of the brain that normally controls That sense can learn to perform another function.
About two million optical nerves are required to transmit visual signals from the retina portion of the eye where light information is decoded or converted into nerve impulses to the primary visual cortex of the brain. With Brain Port, the device is being developed by neuroscientists at Middleton, Wisc.based Wicab, Inc. (a company co-founded in the late Back-and-Rita), visual data are collected through a small video camera Approximately 1.5 centimeters in diameter that is located in the center of a pair of sunglasses worn by the wearer. Bypassing the eyes, the data is transmitted to a handheld base unit, which is slightly larger than a cell phone. This unit contains features such as zoom control, light and shock intensity settings, as well as a central processing unit (CPU), which converts the digital signal into electrical impulses that replace the function of the retina. Part of the challenge of Brain Port is to train the brain to interpret the information it receives through the stimulation device and use it as data of a natural sense. Prototype device research demonstrated that this type of training is possible, since patients with severe bilateral vestibular loss may, after a while, maintain almost normal posture control while sitting and walking, even on uneven surfaces.
