BUÁTECH 2.0: embedded and smart version of the electronic babysitter for deaf parents

The existence of mixed families, where people with and without disabilities coexist, can surpass statistics in real numbers. When it comes to deafness, this relationship presents particular scenarios since deaf individuals face difficulties in performing daily activities, such as identifying when a newborn child is crying. It is noteworthy that in Brazil, there are 10.7 million people with hearing loss, of this total, 2.3 million have severe disability, deafness, which affects 54% of men and 46% of women, where 2 out of every 3 Brazilians who have hearing loss, claim to have difficulty performing some daily activity (Instituto Locomotiva, 2019). From this perspective, Buátech was developed, an assistive technology device that identifies the baby's cry, similar to an electronic babysitter, but differing from these by being designed and developed for use by deaf parents. Buátech's preliminary development, in academia (subject of undergraduted thesis of Design degree’s at UFPB), provided positive responses in relation to the implementation of a low-cost solution, giving rise to rudimentary prototypes (not yet fully functional), where the use of non-optimized generic electronic components was implemented. The project has a patent application filed and an industrial design registration granted, respectively registered under numbers BR102015012753-7 and BR302015002055-5. Given these results, the product was presented to the deaf community and received in a positive way, so there was a window of opportunity in the area of Assistive Technology. Considering this scenario, as a proposal for this dissertation, the improvement of Buátech was envisioned, making use of embedded technologies, digital signal processing and machine learning to later assess its technical feasibility. For this, through artificial intelligence techniques, four prototypes were developed and evaluated.
