Livox — AI-Adaptive Augmentative Communication App Scaled Across Recife's Public Schools

Carlos Pereira, from Pernambuco, Brazil, built Livox — a tablet-based augmentative and alternative communication (AAC) app — to help his daughter Clara, who has cerebral palsy, communicate. The app targets people with cerebral palsy, autism, ALS and stroke-related communication loss.

To give voice and autonomy to people with communication-impairing disabilities via an adaptive touch-calibration algorithm ("IntelliTouch") and customisable pictogram libraries, and to have the tool formally recognised and adopted within Brazil's public school system.

The app uses an adaptive IntelliTouch calibration algorithm that adjusts touch sensitivity to each user's motor ability, combined with roughly 14,000 customisable pictograms available in 25 languages; an eye-tracking version, Livox Capta, has also been developed. After Senator João Capiberibe formally petitioned Brazil's Education Minister in 2013 and a review from the federal Instituto Renato Archer called it "an excellent literacy tool for people with and without disabilities," Recife's municipal school network adopted it into inclusive-education policy, and teachers received formal training on the software (reported February 2016).

Verified figures from ANDI show 500 tablets with Livox deployed in the Recife network — 260 for direct student/family use and 240 across 111 schools with multisensory resource rooms — including a documented case of student Jhonatan Santos using the app in the municipal system. São Paulo's APAE network subsequently partnered with Livox to add users. The app has assisted more than 20,000 people with disabilities overall, is cited as having won a UN "best inclusive technology" recognition and Google's Social Impact Challenge (with roughly R$2.2 million in related investment), and has been used internationally, including at a paediatric rehabilitation programme at a Florida hospital.

No peer-reviewed or randomised outcome evaluation was found; the evidence base rests on documented deployment numbers, a qualitative institutional review, and named case examples rather than a measured study of communication or literacy gains. Some secondary sources cite higher, inconsistent figures that could not be independently confirmed; this description relies only on the ANDI-verified figures.
