The present invention relates to an interactive method of presenting information in an image to a user, who carries a head-mounted display device ( 2+5, 27 ), which presents an image of the surroundings ( 3, 9, 25 ). The method comprises that the user's head position and direction are established in relation to the surroundings and that a calculating device ( 7 ) establishes, based on this, which part of the surroundings is positioned in front of the user's head. Furthermore the calculating device establishes where in a hierarchical scheme the user is positioned as regards information about and performed operations concerning that part of the surroundings which is positioned in front of the user's head and, based on this, which information is to be presented to the user and presents this in the form of a virtual image which is mixed with the real image. The user studies the information and, where required, performs the current operations. A central part of the image is then defined and in the area outside this there are fields and/or objects adapted to be included in a transfer of messages from the user to the calculating device. The user's direction of gaze at the image is then established and it is marked when the point of fixation ( 24 ) in the image is in a field or an object. Finally, the user informs the calculating device that he/she has received the information and, respectively, performed the current operations by looking at fields/objects ( 22, 23 ).
