Abstract

Human figures have been animated using a variety of geometric models including stick figures polygonal models and NURBS-based models with muscles flexible skin or clothing. This paper reports on experimental results indicating that a viewer's perception of motion characteristics is affected by the geometric model used for rendering. Subjects were shown a series of paired motion sequences and asked if the two motions in each pair were the same or differentJhe motion sequences in each pair were rendered using the same geometric model. For the three types of motion variation tested sensitivity scores indicate that subjects were better able to observe changes with the polygonal model than they were with the stick figure model.
