Abstract

"MéTODO DE ENTRADA E SAìDA DE INFORMAçãO COM UTILIZAçãO DE UM PADRãO DE PONTOS". Atribuindo-se diferentes funções aos respectivos pontos de um padrão de pontos durante a obtenção de informação proveniente de um padrão de pontos, é possível reconhecer a direcionabilidade e rapidamente obter informação, bem como verificar um erro do estado do arranjo de pontos, melhorando assim ainda mais a segurança. Uma pluralidade de pontos da grade fica arranjada em uma forma no geral regular como um bloco. Blocos são arranjados de forma regular e contínua. Um ponto da grade contido no bloco dos pontos da grade arranjado na forma retangular e deslocado em uma direção predeterminada é usado como um código chave. O código chave serve como um ponto representativo, e um centro envolto por pontos da grade de quatro pontos e arranjados na periferia do ponto chave é feito um ponto virtual. Em um ponto final de um vetor de direção que começa no ponto virtual, uma pluralidade de pontos de informação para reconhecer várias informações fica arranjada de acordo com uma regra predeterminada, criando-se assim um padrão de pontos. O padrão de pontos é capturado como dados de imagem por meio de uma câmara e digitalizado para se obter um valor numérico, do qual informação e programa são emitidos.
