Abstract

É fornecido um dispositivo head-mounted display (HMD) (100) configurado para ser vestido por um usuário (121). O HMD compreende um display pelo menos parcialmente transparente (101), uma câmera frontal (102) operativa para capturar uma primeira imagem de uma cena do mundo real e meios de processamento (104) que são operativos para selecionar um objeto de calibração dentre um ou mais objetos do mundo real, ou partes dos mesmos, (130?135) que são visíveis na primeira imagem e para derivar uma transformação de calibração para calcular uma posição de display com base em uma posição do mundo real, de modo que um objeto virtual que é exibido no display na posição de display esteja alinhado com um objeto do mundo real correspondente localizado na posição do mundo real, conforme visto pelo usuário.
