Abstract

"CODIFICAçãO ATIVA COM INTERAçãO EMBUTIDA". é descrito um sistema e método para proporcionar um esquema de codificação para um fluxo de bits e exibir ou imprimir o fluxo de bits codificado. Utilizando o fluxo de bits codificado, uma caneta com uma câmara pode capturar uma imagem de uma parte do fluxo de bits codificado. A imagem capturada pode então ser decodificada para proporcionar uma indicação da localização da imagem em relação ao fluxo de bits codificado. o esquema de codificação inclui informação com respeito à orientação, assim tornando a decodificação mais fácil.
