Abstract

a presente invenção se refere ao problema de prover uma folha de assistência de entrada de informação tendo impresso, pontos de absorção de luz infravermelha e configurada para permitir luz infravermelha refletida em uma região muito pequena a ser lida de forma confiável independentemente de um ângulo de contato de um dispositivo de leitura óptica quando lê um padrão de ponto de uma luz infravermelha que foi emitida por uma fonte de luz do dispositivo de leitura óptica e refletida pela folha de assistência de entrada de informação. a folha de assistência de entrada de informação é distinguida pelo fato de que: os pontos no padrão de ponto são impressos em uma folha transparente usando tinta de impressão capaz de pelo menos absorver luz de um comprimento de onda predeterminado ou capaz de tanto absorver luz do comprimento de onda predeterminado e passar luz visível; e uma camada de reflexão difusa é formada arranjando material de reflexão direcional de modo que a luz do comprimento de onda predeterminado emitida pelos meios de emissão é refletida de forma difusa por uma superfície legível por padrão de ponto.
