Abstract: A device, system and method for determining a position of a movable object on a two-dimensional surface obtains, via an image capture device attached to the movable object, at least one image of a portion of the two-dimensional surface. At one virtual marker is identified in at least one image, and a previously determined estimated position of the at least one virtual marker is retrieved. The previously determined estimated position determined from a combination of an image of at least one anchor point on the two-dimensional surface, the at least one anchor point defining a unique position on the two-dimensional surface, and odometry measurements based on at least two images of the two-dimensional surface. The position of the movable object on the two-dimensional surface is determined from the estimated position of the at least one virtual marker.

Abstract: The invention relates to: A method of utilizing the time span between a request (101) for first pieces of information from a user unit (1; 11) to an information server (5) via a node (2) in a network and the reception of said first pieces of information (108) at the user unit (1; 11). The invention further comprises a computer readable medium, a system and a software program related to the method. The object of the present invention is to disclose an alternative method of presenting additional information to a user during the time span between a user's request for information from an information server and the reception of said information.
