Abstract
This work describes the design and implementation strategies used
in the development of an interactive spatialized multimodal display
for the exploration of the light curves from the Convection,
Rotation and planetary Transits (CoRoT) archive from the Institut
d’Astrophysique Spatiale (IAS). The application displays the
representations in a user-selectable Ambisonics or Binaural configuration
based on the actual coordinates of the objects. Each
sonification is based on a symbolic spectral-type to musical-note
mapping strategy, providing musical aesthetics and auditory spectral
differentiation capability. The UI shows the footprint of 474
objects from the CoRoT N2 legacy data release and a sequential
representation of its light curves. It is designed to be used in outreach
activities and archival accessibility improvement. The work
includes a user study with 40 participants experienced and nonexperienced
in Astronomy and Music, that analyzes the usefulness
of the proposal for auditory stellar spectra classification with the
support of training videos. Although the results should be considered
indicative, they suggest that non-experienced participants
can retrieve useful information through sound to complete the task
with an average success rate around 0.47, while experienced participants
do it with an average success rate around 0.72.
