Abstract:
In augmented reality, virtual graphical objects are overlaid over the real environment of the
observer. Conventional augmented reality systems use standard computer graphics methods for
generating the graphical representations of virtual objects. These renderings contain the typical
artefacts of computer generated graphics, e.g., aliasing caused by the rasterization process and
unrealistic, manually configured illumination models. Due to these artefacts, virtual objects
look artificial and can easily be distinguished from the real environment.
Recently, a different approach to generating augmented reality images was presented. In
stylised augmented reality, similar types of artistic or illustrative stylisation are applied to the
virtual objects and the camera image of the real environment [1]. Therefore, real and virtual
image elements look more similar and are less distinguishable from each other.
In this poster, we describe the results of a psychophysical study on the effectiveness of
stylised augmented reality. A number of participants were asked to decide whether objects
shown in images of augmented reality scenes are virtual or real. Conventionally rendered as
well as stylised augmented reality images and short video clips were presented to the participants.
The correctness of the participantsamp;amp;8217; responses and their reaction times were recorded.
The results of our study clearly show that an equalized level of realism is achieved by using
stylised augmented reality, i.e., that it is distinctly more difficult to discriminate virtual objects
from real objects.
