ABSTRACT:
An alignment aiding method and apparatus enables an orienting and positioning of a data carrying 2-dimensional graphical symbol within a field of view of an imaging device. The desired orientation and position is indicated by a graphical alignment indicator. The graphical alignment indicator is displayed in a fixed position on a display device, while an image of the graphical symbol is also displayed, and preferably updated and refreshed at a suitable refresh rate to provide usable feedback. While being displayed, the graphical symbol may be moved, oriented, and positioned, thereby enabling a substantial aligning of the data carrying 2-dimensional graphical symbol with the graphical alignment indicator. This abstract is provided to comply with rules requiring an abstract, and is submitted with the intention that it will not be used to interpret or limit the scope and meaning of the claims.
