O presente projeto busca o aperfeiçoamento e o desenvolvimento (aprimorado) de um protótipo em escala comercial de um dispositivo chamado de Óculos Mouse, que permite o uso do computador por pessoas que possuam algum tipo de paralisia motora (especificamente com movimento parcial ou nulo nos braços e pernas, por exemplo, pessoas tetraplégicas). Tal dispositivo, que foi desenvolvido e patenteado por uma equipe de professores e alunos do curso técnico de mecatrônica do Instituto Federal Sul-Rio-Grandense apresenta viabilidade social e econômica para ser inserido dentro da rede dos Institutos Federais, bem como nos diversos centros de apoio e atendimento a pessoas com necessidades especiais do Brasil. O presente projeto prevê o aprimoramento da eletrônica e interface do dispositivo considerando também o aperfeiçoamento do design e ergonomia do protótipo em relação à primeira versão do mesmo (desenvolvida e patenteada dentro do IF-Sul).
The nowUP project is based on a service that automatically creates summaries of TV programs supported on the buzz on social networks.
