  Edukoi is a software that aims to make interactive sonification suitable to
convey and extract information. The program design is a modification of the
software Herakoi, which sonifies images in real time mapping pitch to colour
using a motion-aware approach for allowing users to interact with images
through sound. The pitch-colour association of Hearkoi, albeit pleasing from
the entertainment side, is not efficient for communicating specific information
regarding colours and hues to listeners. Hence we modified it to create an
instrument to be used by visually impaired and sighted children to explore
images through sound and extract accurate information. We aim at building a
flexible software that can be used in middle-schools for both art and science
teaching. We tested its effectiveness using astronomical images, given the
great fascination that astronomy always has on kids of all ages and
backgrounds. Astronomy is also considered a very visual science, a
characteristic that prevents students from learning this subject and having a
related career. With this project we aim to challenge this belief and give to
students the possibility to explore astronomical data through sound. Here we
discuss our experiment, the choices we made regarding sound mappings, and what
psychophysiological aspects we aim to evaluate to validate and improve Edukoi.
