Assistive communication device for individuals with paralysis

Abstract

Patients suffering from diseases like paralysis, ALS are very dependant upon attendants, even for the simplest of everyday acts. However, suitable assistive texnology can give suh individuals improved independence. The present project is very unique collection in the field of Component based assistive technology and systems. This system provides a possible new solution for a human-computer interaction system that can be used for highly disabled people. Such patients are not able to move their limb unable to speak; henceforth we have fabricated a system such that patient can communicate with the outside worl with the help of eye blinkto fulfill their basic needs. The patient can liste and understand everything. Therefore we can teach him directions for using the system. After learning the directions, he can convery a message in the form of eye flickering. The flickering of eye gives a signal to the sensor while the open eye gives no signal and for every signal there is a message at the computer screen. Whilst such a system does not represent the best interactive approach for all users in all situations, it does represent an important and useful option for individuals with movement restrictions.
