SAPLM “Sistema Auxiliar para Personas con Limitaciones Motrices” (English: Auxiliary System for People with Mobility impairments) was a final year project for technical school that aimed to develop a system that helped people with mobility impairments to control appliances and communicate with others by just the use of their voice.
The system itself could be categorized as a home automation system but heavily thought of as an extension of a clinical setup.
The project development and testing was mainly carried out at the school facilities, E.E.S.T. N°9 Prof. Antonio Jose Rodriguez.
Project developers: Da Cruz, Agustín; Villegas, Rocío; Zatloukal Maule, Julián.
Project supervisors: Otero, Diego; Castro, Pujol; Della Paolera, Sergio
During all of 2019, from February to the end of November, as a group of three we developed the project and made progress almost every day throughout the year. The final result allowed the user to use their voice as a trigger of electric appliances such as an electric fan, a bulb, a desk lamp, an electric stove, and even control a small curtain. The Android application used Google's voice-to-speech API to recognize the user’s speech and send the text to the main board and then fulfill the action.
