An AR Human Computer Interface for Object Localization in a Cognitive Vision Framework

Abstract. In the European cognitive vision project VAMPIRE (IST2001-34401), mobile AR-kits are used for interactive teaching of a visual active memory. This is achieved by 3D augmented pointing, which combines inside-out tracking for head pose recovery and 3D stereo HCI in an office environment. An artificial landmark is used to establish a global coordinate system, and a sparse reconstruction of the office provides natural landmarks (corners). This paper describes the basic idea of the 3D cursor. In addition to the mobile system, at least one camera is used to obtain different views of an object which could be employed to improve e.g. view based object recognition. Accuracy of the 3D cursor for pointing in a scene coordinate system is evaluated experimentally.
