Evaluating human factors in augmented reality systems

Augmented reality (AR) has been part of computer graphics methodology for decades. A number of prototype AR systems have shown the possibilities this paradigm creates. Mixing graphical annotations and objects in a user´s view of the surrounding environment offers a powerful metaphor for conveying information about that environment. AR systems´ potential still exceeds the practice. In fact, most AR systems remain laboratory prototypes. There are several reasons for this; two of the most prominent are that researchers need more advanced hardware than currently available to implement the systems, and (the subject of this article) the AR research community needs to resolve human factors issues. AR systems are usually interactive; thus, we must verify usability to determine if the system is effective.
