Abstract
Obtaining an overview is an important first step in the analysis of data sets, which cannot be easily done nonvisually with current accessibility tools. We present TableVis, a multimodal interface to obtain overview information from numerical data tables non-visually, with the use of an interactive sonification technique controlled from a tangible physical device (a tablet). An experimental study with TableVis is reported, in which it is found that performance is highly insensitive to the size of the data set being explored, for a broad range of data set sizes.
