Topic: Eyes on the prize, bionic vision

Description: This research explores the path that has begun with improving human vision through head pieces and glasses to contact lens that can aid a human to see better than 20/20 and link their vision to computer devices.

Motivation: Bionic vision is an important area of research with a significant impact on blind people who could see again by implanting computer chips in the brain and using bionic glasses. The military can use these lenses to improve a pilot or soldiers vision to give them an aid in battle. Video games, movies, iphones and your computer could be brought right to your field of vision.

[A blind woman from Missouri participated in a rare operation to give her sight. She is only the 16th person in the world to have surgery wiring a sci-fi device to her brain. The device functions as a prosthetic cornea, by directing light to the interior of the eye. An eye piece is placed on a pair of sunglasses and connected to an electrode inside her skull. Then a camera sends video signals to a computer which then interprets the information and sends it through two cables plugged into her skull. The electrode now stimulates her brain, which creates a dot matrix image. All sixteen operations have been done in Portugal because the FDA prohibits the procedure due to its possible risks. The procedure during the date of the article is only available for people he have had sight at one time and lost it. ]

[This paper explains the history of how EyeTap technology came about and how it is used and can be used in the future. The author wants to use the device as a lifelong cyborglog, where the glasses will record everything that it sees. First you have the electric glasses that unlike tradition glasses can modify light computationally where in the future prescriptions could be downloaded. The lifelong cyberlog of glog could help people remember better but just recall past recorded events in ones’ life. This device started as a big clumpy device over the eyes and in the past 30 years or so of its development has come down to the size of everyday eyeglasses. As a form of electric seeing aid, surveillance system, and wearable camearaphone, this device functions as natural extensions of the mind and body. The research and testing of the device has come very far but the difficulties holding it back now are problems of inequiveillance which is the imbalance between surveillance and sousveillance. ]

[This article focuses on the possibilities of such technology being fused with the human body. Like eagle like vision and curing blindness. The author goes through a brief history of an optic system that strives to improve vision through computer technology. Super normal vision something you see in comic books and cartoons is becoming a reality. People no longer have to settle for just 20/20 vision with the help of glasses of contacts. They can according to the author obtain supernormal vision. Humans went from using goggles to see in the dark or binoculars so see far to recent technogly that enables the human eye to see finer detail than ordinarily possible. David R. Williams of the University of Rochester has developed an approach to obtain this vision. He took a method of adaptive optics, originally used by the military to sharpen images. The goal of this technology is to improve human vision but in the present focus on preventing vision loss and correcting eyesight problems. ]

[The author describes the possible capabilities of a contact lenses created by a team at the University of Washington. This contract lens combined with a computer chip will be able to connect to wireless device and provide a visual image of the device in your field of vision. High –resolution images will be displayed before you of games, texts, and music. This idea came about when they felt that they could make a really tiny functional device that could be imbedded into a contact lens. Babak Parviz, professor at the University of Washington is a leader in the research and development of this technogoly. He told The Times.” Our goal is to integrate a display which can do everything that an iPhone or computer does now – but in front of your eye. A user could manipulate the document by blinking or by using his voice.” A metal circuit and light –emitting diodes are placed in a polymer-based lens, where the lens is biologically compatible with the eye. Ultra-thin antennas, a few nanometers thick, are used to send information wirelessly to devices.]
