Human language is a direct communication among human beings to express his/her emotions and thoughts. It is easy for most of us to express their thoughts through languages, but the ALS (Amyotrophic Lateral Sclerosis) victims, it will be a fantasy. If a computer system can help those patients to communicate with outside world, then it will be a great help for the families and doctors whose responsibility is taking care of them.
My research is to build English Letter expression system based on Electro-oculography. When a user wants to express him/herself, he/she simply needs to revolve his/her eyeballs clockwise three times, and the system will be initiated. After finishing each alphabet, if the users take a glance at a point one second, the system will recognize that the users have finished one alphabet; if the users are done with “writing,” he/she just needs to gyrate his/her eyeballs counterclockwise three times, and the system will be at a standby mode; the users can activate the system at any time.
In my research, I used electrode to get both horizontal and vertical signal from eyeballs. Once the signals were picked, it will be magnified 334 times by Differential Amplifier, and then signal will be transmitted to the computer by analog-digital converter. After that, the computer will manage the signal and the recognize alphabets. The signal management includes: filtering disorderly signals, classifying codes, and detailed sorting for Hopfied Neural Network.
In this system, I established 33 symbols to facilitate users, including 26 Latin alphabets, four commonly used punctuation symbols (space, comma, question, and dot), and three symbols (cancel letter, cancel word, and cancel sentence). Users will be able to communicate with and express to others easily using those 33 symbols. |
