Kansas University sophomore Natali Diaz, of Overland Park, moves her arms and hands in front of a computer screen during a workshop for the Adaptive Use Musical Instrument (AUMI) software on Friday at Independence Inc., 2001 Haskell Ave. Representatives from the Deep Listening Institute, based out of Kingston, N.Y., explained how the software, which is designed to produce sound as it tracks facial or body motion through a Web camera, can be used as a stimulating activity for special needs children or adults with limited mobility. Members of the Kansas University School of Dance, educators, therapists and local residents participated in the workshop. The software can be downloaded for free at deeplistening.org.
