Presented at the 19th International Conference on Auditory Display (ICAD2013) on July 6-9, 2013 in Lodz, Poland.In this research we present an interactive tabletop installation
ÒHakoniwaÓ. It consists of a wooden box, white sand and
painted woodblocks. In this system, corresponding to the
arrangement of woodblocks, a ceiling-mounted projector shows
visual effects on the sand surface. At the same time, generative
music is composed in a computer corresponding to the
arrangement of woodblocks and modeling of the sand. This is an
attempt of sonification of miniature garden. We studied
Sandtray therapy, one of a famous form of art therapy, as a
motif of the installation. We directed our attention to tactile
sensation of sand and woodblocks, and tried to extend sandtray
using computer vision processing and multi-media output. In
this paper we describe details of the interactive system and
discuss the possibility of supporting primitive play using such
interactive systems
