AAC Device

Augmentative and Alternative Communication (AAC) is all forms of communication that are used to expressed thoughts, needs, wants and ideas. AAC serves as an alternative to people who cannot speak. It is a method used to replace or supplement speech for persons with disabilities.

There are two types of AAC - aided and unaided.The unaided type relies on the body to convey messages. This includes gestures, sign language and body language. The aided system uses tools or equipment in addition to the body to communicate. This includes low tech devices such as paper and pencil to high tech devices such as an iPad with a speech to text app or a communication board.

Example of an AAC Device

The Eye-Speak is a communication system that uses the eyes, it is designed for people with extreme mobility and communication problems such as ALS, LIS, MD, and SCI. This device will write and speak for you. This device 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.
