  Most tools for astrophysical research was centered on visual display. Even
after some studies shows that the use of sound could help the data analysis,
and on the other hand generate more accessibility. This fact motivates the
creation of a tool centered on the researcher with and without visual
impairments. To carry out this challenge, on this contribution, a theoretical
framework based on visual impaired people was created and included on the
sonoUno software. After that, the accessibility of the tool was analysed with
the ISO standard 9241-171:2008.
