Abstract

A velocidade ea precisão do reconhecimento de objetos é comprometida por uma mudança no ponto de vista; demonstrando que observadores humanos são sensíveis a esta transformação. Aqui nós discutimos um novo método para simular a aparência de um objeto que foi submetido a uma profundidade de rotação em-, e incluem uma exposição das diferenças entre a perspectiva e projeções ortográficas. Em seguida, descrevem um método pelo qual a sensibilidade humana para rotação em profundidade pode ser medido. Finalmente discutimos um aparelho para criar uma percepção vívida de um 3-dimensional rotação em profundidade, o Wheatstone Oito Espelho Stereoscope. Ao fazer isso, nós revelamos um meio pelo qual se avalia o papel de sugestões estereoscópicas na discriminação de ponto de vista girada formas e objetos.
