Abstract

We are developing a sound-based, interactive, data-plotting program to enable the visually impaired to turn astronomical data into meaningful sounds. The sonification software, called "splot", would be available to any scientist to analyze data. Splot reads ASCII data files containing various plotting commands and other data, and then outputs sounds corresponding to the data instead of plotting to a display or a printer. Input data for splot is partially compatible with "qdp", a data-plotting program developed by NASA HEASARC. In this paper, we report the status of development. In the current version, splot only sonifies a one-dimensional histogram and thus remains an experimental production. Before releasing this software, we must extend its functions for a suitable field test and construct a data-analysis environment for the visually impaired.
