Abstract

MÉTODOS E SISTEMAS PARA CONTROLE DE UM DISPOSITIVO BASEADO EM GESTOS DE MÃO. A invenção diz respeito a métodos e sistemas para controle baseado em gesto de um dispositivo. Um quadro de entrada é processado para determinar uma localização de uma característica anatômica distintiva no quadro de entrada. Um espaço de gestos virtual é definido baseado na localização da característica anatômica distintiva, o espaço de gestos virtual sendo um espaço definido para detectar uma entrada por gesto. O quadro de entrada é processado somente no espaço de gestos virtual, para detectar e rastrear uma mão. Utilizando informação gerada a partir de detectar e rastrear a pelo menos uma mão, uma classe de gesto é determinada para a pelo menos uma mão. O dispositivo pode ser uma televisão inteligente, um smartphone, um tablet, etc.
