Abstract

DETECÇÃO DE PRESENÇA DE USUÁRIO DE DISPOSITIVO DE COMPUTAÇÃO. Um dispositivo de computação (108) pode detectar a presença de um usuário após o usuário não ter interagido com o dispositivo de computação (108) por um período de tempo predeterminado. O usuário pode deixar o dispositivo (1908) ligado, mas após o período de tempo predeterminado ter expirado, o dispositivo (108) entra em um modo de detecção de usuário a partir de um modo de operação normal, de tal modo que componentes não essenciais são desligados. Um trackpad (141) pode ser usado para detectar a presença do usuário no modo de detecção de usuário. Um campo elétrico (310) é gerado por placas condutivas do trackpad (141). Quando o usuário estende sua mão sobre o trackpad (141), linhas de detecção no trackpad (141) detectam a interferência com o campo elétrico (300) provocada pela mão. Um processador (124) é sinalizado para retornar o dispositivo (108) para o modo de operação normal e restaurar a plena energia para o dispositivo (108). Uma câmera (500) também pode ser usada para detectar a presença do usuário durante o modo de detecção de usuário.
