| Summary: | Astronomy’s dependance on visual perception makes it difficult to be
accessed by the visually impaired. Nevertheless, there are efforts to
communicate astronomy to the visually impaired with the help of auditory
perception and tactile perception. Screen reader applications are
accessibility tools which help the visually impaired perceive images with
the help of words. One of the disadvantages of screen reader is abstract
astronomy concepts may be difficult to be recognized, especially for those
who are visually impaired since childbirth. In this research, an image
sonification program is designed as an alternative to screen reader
applications to communicate astronomical images to the visually impaired
using shape-approach sonification. The program was written using Python
3.8 programming language. The program is able to sonify shapes
automatically and is also responsive to changes and differences in shapes.
The program produces a MIDI file which is then polished and exported
using DAW to create music in the form of MP3 file. After a series of
evaluation with the help of six people with visual impairment, this method
of sonification has the potential as an alternative to the accessibility of
astronomical images for the visually impaired with sufficient practice.
