Communication for technology provides those who have communication challenges a way of expressing their wants and needs. People of all ages and abilities can use and benefit from using communication technology. There are four categories of technology for communication. They include voice output technology, symbol communication technology, auditory technology and Eye Gaze communication technology. Voice output technology are devices that allow a person to select a picture, word, phrase or sentence, which is read aloud by the device. Symbol communication includes pictures that are used to communicate with others by having the pictures represent items, actions and thoughts of the person communicating. Auditory technology is used with people who have hearing impairments where the impairment inhibits the person's ability to communicate effectively with others. The person with the hearing impairment usually wears a receiver and the person who is communicating with them wears a microphone. Lastly, Eyegaze technology is used with individuals with limited speech and motor skills to allow them to use eye movement to communicate.
