  The aim of the authors' research is to gain better insights into the
effectiveness and user satisfaction of anthropomorphism at the user interface.
Therefore, this paper presents a between users experiment and the results in
the context of anthropomorphism at the user interface and the giving of
instruction for learning sewing stitches. Two experimental conditions were
used, where the information for learning sewing stitches was the same. However
the manner of presentation was varied. Therefore one condition was
anthropomorphic and the other was non-anthropomorphic. Also the work is closely
linked with Hartson's theory of affordances applied to user interfaces. The
results suggest that facilitation of the affordances in an anthropomorphic user
interface lead to statistically significant results in terms of effectiveness
and user satisfaction in the sewing context. Further some violation of the
affordances leads to an interface being less usable in terms of effectiveness
and user satisfaction.
