Traditionally, assembly instructions are written in the form of paper or digital manuals. These manuals contain descriptive text, photos or diagrams to guide the user through the assembly sequence from the beginning to the final state. To change this paradigm, an augmented reality system is proposed to guide users in assembly tasks. The system recognizes each part to be assembled through image processing techniques and guides the user through the assembly process with virtual graphic signs. The system checks whether the parts are properly assembled and alerts the user when the assembly has finished. Some assembly assisted by augmented reality systems use some kind of customized device, such as head mounted displays or markers to track camera position and to identify assembly parts. These two features restrict the spread of the technology whence, in this work, customized devices and markers to track and identify parts are not used and all the processing is executed on an embedded software in an off-the-shelf device without the need of communication with other computers to any kind of processing.
