The EyeSpeak is a communication system through the eyes, especially designed for people with extreme mobility and communication limitations caused by different types of illness or injury.

The EyeSpeak consists of a pair of glasses in which the lenses display a screen with a virtual keyboard. It has a micro camera that detects the position and the movement of the eyes and, in this way, identifies the key the user is looking at.

The user selects the keys with the movement of the eyes, being able to write words and phrases. Then, using the built-in speaker system, the user translates what was written into sound by selecting the key "speak" after typing a word or phrase.

The innovative EyeSpeak system allows the user to communicate at any place or physical location, without the need for assistive devices such as computer, laptop or tablet.

Any person can use the EyeSpeak autonomously, because the only help that the user needs is someone to put the glasses on the face and press the "ON" button to turn it on.

The user can also go to the Internet, view videos, and access to emails with privacy, as no one else can see what is being projected on the screen. Communicate via Skype is another of the possibilities that the EyeSpeak provides!

Additionally, while communicating or using the Internet, the user of the EyeSpeak can observe all the surrounding context, through the transparent lens of the device, maintaining a close connection with reality.
