Interactive information display method for mixed reality system, monitors visual focal point indicated field or object in image obtained by mixing virtual and actual images

摘要

A computer (7) determines the location of the user in a hierarchical scheme and retrieves information relating to the surrounding environment (3) in front of the user's head, then it decides which information is to be displayed and presents it in the form of a virtual image which is mixed with the actual image. A central part of the image is defined and the image field (22) and/or objects (23) outside this central part are included in a message sent from the user to the computer. The vision direction of the user in the image is determined and the focal point (24) is indicated in a field or object in this image. The computer informs the user as to whether they have received information or performed a movement depending on how the focal point is positioned in the field or object. The user wears an image display device on the head and the position and direction of the head in relation to the surrounding environment are monitored.
