Volume visualization using 2-D slices is a technique exploited in several scientific fields such as medicine, geology or any other industrial application using 3D data. The expert has the possibility to explore the data by displaying a set of slices extracted from the volume. The objective is to detect some specific three-dimensional structure and point it in 2-D, directly on slices with a device. This type of interaction realized during the animation of slices is named dynamic pointing. To formalize this task we define in this article a new paradigm: the dynamic steering task (DST). We first relate it with the other tasks studied in Human-Computer Interaction. This study helps us to better understand the reason of the difficulty of this task and why users produce so many positioning errors. We formulate the hypothesis that the errors generated in a DST are coming from the impossibility for the experts to anticipate the structural variations of the structures to be pointed. In order to solve this problem we propose a new technique of visualization, which facilitates anticipation, called the projective slice. The effectiveness of this tool and the veracity of our assertions are determined experimentally. |
