Proloquo2Go [iTunes Link] is not your usual iPhone/iPod touch app. It turns the mobile device into a full augmentative and alternative communication (AAC) device. According to the AAC Institute, an estimated 2.5 million Americans are speech disabled to the extent that they experience significant difficulty being understood by other people. Reasons vary, but are often the result of congenital illness or ALS (also known as Lou Gehrig's disease). 75% of people using AAC devices have ALS. One alternative is learning how to use sign language, but that requires both adequate sensory motor ability of the user and a knowledge of sign language expected in the listener. It's a solution that helps some, but not all.
When signing is not available or appropriate, using an AAC device may well be. AAC devices use combinations of symbols, words, sounds and technology to allow people without functional vocal abilities to communicate. The cost of such devices range from around US$3,500 to US$8,500 for something about the size of a Speak and Spell.
In contrast, the Proloquo2Go app has a price of US$189.99. If someone is in the market for an AAC system, it is one of the biggest bargains in the entire App Store for any iPhone or iPod touch running OS 2.1 or higher.
Proloquo2Go took the uncommon route of using existing hardware to run a complex AAC system. It's nearly impossible to describe the use of the system through words, though I'll try, but I'd suggest you check out some detailed videos walking you through the process in some depth.Read more →
