Abstract

a presente invenção refere-se a modalidades que estão descritas para sistemas e métodos de rastreamento de olho. um exemplo de um sistema de rastreamento de olho compreende uma pluralidade de fontes de luz e uma câmera configurada para capturar uma imagem de luz das fontes de luz como refletidas de um olho. o sistema de rastreamento de olho ainda compreende um dispositivo lógico e um dispositivo de armazenamento que armazena instruções executáveis pelo dispositivo lógico para adquirir quadros de dados de rastreamento de olho iterativamente projetando luz de diferentes combinações de fontes de luz da pluralidade de fontes de luz e capturar uma imagem do olho durante a projeção de cada combinação. as instruções podem ainda ser executáveis para selecionar uma combinação selecionada de fontes de luz para rastreamento de olho com base em uma determinação de oclusão detectada na imagem que surge de uma estrutura ótica transparente ou semitransparente posicionada entre o olho e a câmera e projetar luz através da combinação selecionada de fontes de luz para rastreamento de olho.
