TEAjudo CAA

Features
Read full description

TEAjudo CAA é um sistema de Comunicação Aumentativa e Alternativa (CAA) desenvolvido para crianças e adolescentes com autismo (TEA), paralisia cerebral e outras condições que afetam a comunicação verbal. Com uma interface acessível, intuitiva e personalizável, o TEAjudo CAA permite que a criança se expresse com autonomia — usando pictogramas, fotos e símbolos organizados em pranchas adaptadas à sua rotina e ao seu contexto. PARA QUEM É O TEAJUDO CAA? Crianças e adolescentes com Transtorno do Espectro Autista (TEA) Pessoas com dificuldades de comunicação verbal Fonoaudiólogos, terapeutas ocupacionais e psicopedagogos Pais, cuidadores e professores de educação especial RECURSOS PRINCIPAIS PRANCHAS PERSONALIZÁVEIS Crie e organize pranchas por categorias — alimentação, rotina, emoções, escola e mais. Adicione fotos da própria criança para maior identificação. BIBLIOTECA ARASAAC Acesso a milhares de pictogramas gratuitos do maior acervo de CAA do mundo, utilizado por terapeutas em mais de 100 países. VOCABULÁRIO NÚCLEO Mais de 200 palavras de alta frequência pré-carregadas para comunicação funcional imediata. SÍNTESE DE VOZ (TTS) Cada símbolo fala ao ser tocado. Ajuste voz, velocidade e tom individualmente por perfil de usuário. ROTINAS AUTOMÁTICAS As pranchas mudam automaticamente conforme o horário do dia — café da manhã, escola, lazer, jantar. Menos configuração para o terapeuta, mais previsibilidade para a criança. SUGESTÃO DE PRÓXIMA PALAVRA POR IA O app sugere a próxima palavra enquanto a criança monta o enunciado, usando inteligência artificial. Menos toques, comunicação mais fluente. CÂMERA → PICTOGRAMA Fotografe um objeto real e o app encontra automaticamente o pictograma ARASAAC correspondente usando visão computacional. SOCIAL STORIES Crie histórias sociais visuais dentro do app para preparar a criança para novas rotinas e situações desafiadoras. SCRIPTS DE COMUNICAÇÃO SOCIAL Frases prontas para situações do cotidiano: pedir ajuda, cumprimentar, solicitar lanche. O terapeuta monta, a criança usa com confiança. MODO ESPELHO Conecte dois iPads para sessões em tempo real: o terapeuta acompanha e interage na mesma prancha da criança, ideal para atendimentos presenciais e online. HISTÓRICO COM A FAMÍLIA Os pais acompanham no celular o que a criança comunicou durante o dia, com horário e contexto de cada mensagem. PORTAL WEB PARA TERAPEUTAS Configure pranchas, acompanhe o histórico e gerencie rotinas pelo computador, sem precisar do iPad. ANÁLISE CLÍNICA Heatmap de uso, painel de progresso e exportação de relatórios em PDF para compartilhar com a equipe terapêutica. VARREDURA POR SWITCH Suporte a varredura automática com 1 ou 2 botões externos para usuários com mobilidade reduzida. PERFIS MÚLTIPLOS Cadastre vários usuários no mesmo dispositivo, cada um com suas pranchas, voz e configurações independentes. PRIVACIDADE E SEGURANÇA Os dados ficam armazenados localmente no dispositivo. A sincronização em nuvem é opcional e protegida. Sem publicidade. Sem coleta de dados de terceiros. O TEAjudo CAA é uma ferramenta de apoio terapêutico — não substitui o acompanhamento de profissionais de saúde.
