Patent number: 8063849Abstract: A method for a user to navigate in a surrounding world captured by one or more image sensors and displayed to the user in an image display area of a display device which in use is in front of the user's head and follows the movements of his head. When the user's head is directed in an area which the user can easily reach by turning his head, the display is controlled by his head direction. When the head direction reaches the edge of what the user can reach by turning his head, use is instead made of controlling by gaze direction of that displayed, in which case the point of the surrounding world pointed out by the gaze direction is continuously placed in a predetermined area of the image. The change occurs either automatically by the user's gaze direction being at the edge of the image display area or by a command, for instance with the user's voice or a motion of his hand.Type: GrantFiled: April 28, 2006Date of Patent: November 22, 2011Assignee: Totalförsvarets ForskningsinstitutInventors: Torbjörn Gustafsson, Per Carleberg

Patent number: 7948451Abstract: An interactive method of presenting information in an image to a user, who carries a head-mounted display device that presents an image of the surroundings. The user's head position and direction are established in relation to the surroundings and a calculating device 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 chain of information the user is positioned and, based on this, presents information in the form of a virtual image which is mixed with the real image. A central part of the image is then defined and fields and/or objects outside this area are shown in a non-disturbing way until the user's gaze has left the central part. The user informs the calculating device that he/she has received the information and, respectively, performed the current operations by looking at the fields/objects.Type: GrantFiled: June 17, 2005Date of Patent: May 24, 2011Assignees: Totalförsvarets Forskningsinstitut, Försvarets MaterielverkInventors: Torbjörn Gustafsson, Per Carleberg, Peter Sohlberg, Bo Persson, Christina Aldrin

Publication number: 20080024392Abstract: 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.Type: ApplicationFiled: June 17, 2005Publication date: January 31, 2008Inventors: Torbjorn Gustafsson, Per Carleberg, Peter Sohlberg, Bo Persson, Christina Aldrin

Publication number: 20070247457Abstract: A device and a method for displaying an image of the surroundings to a user (90), comprising an image sensor device (10), which records image information of a surrounding world, connected via a transmission device (20) to a central unit (30), and a head-mounted display device (40), where the central unit (30) displays images from the image sensor device (10). The invention comprises that the central unit (30) generates a virtual 3D world where image information (8) is projected in real time from the image sensor device (10) as textures in a 3D world. Parts of the 3D world are then displayed on the display device (40) in real time.Type: ApplicationFiled: June 21, 2005Publication date: October 25, 2007Inventors: Torbjorn Gustafsson, Per Carleberg

Publication number: 20040135973Abstract: The present invention relates to a display device with variable focusing depth. The display device presents from electrical signals an image built up of at least two sub-images for the eye (7) of an observer. Focusing depth is generated in the image by different sub-images being generated with different focal distances and that objects in the image are distributed in the sub-images with regard to the depth effect one intends to create in the image.Type: ApplicationFiled: November 10, 2003Publication date: July 15, 2004Inventors: Torbjorn Gustafsson, Stan Zyra

Patent number: 6648479Abstract: A device for screening interfering radiation from a radiation source from reaching a radiation receiver. The device includes a sensing device determining the position and orientation of the radiation receiver relative to the radiation source; a matrix, positioned in front of the radiation receiver, of elements which can adopt a varying transmittance and which cover the solid angle within which it is desirable to screen interfering radiation; and control equipment which calculates in what position relative to the radiation receiver a radiation obstacle is to be placed to be able to screen the radiation source and which controls the elements of the matrix in such a manner that the matrix forms a partial or complete radiation obstacle in the estimated position.Type: GrantFiled: June 1, 2001Date of Patent: November 18, 2003Assignee: Totalforsvarets ForskningsinstitutInventors: Torbjörn Gustafsson, Stan Zyra
