A Study on the Use of Motion Graphics and Kinect in LMA (Laban Movement Analysis) Expression Activities for Children with Intellectual Disabilities

Abstract

The purpose of this study is to the motion expression activities of children with intellectual disabilities using motion graphics and Kinect. In the process of recognizing movement expression activity using motion graphics and Kinect, the effect of performance was shown when the movement expression activity through the body was properly performed. The subjects were 8 children with intellectual disabilities, and conducted the program twice a week for 10 weeks. The research design utilized video screen and theme music as contents of musical works. 42 actions were performed randomly. When the movement is perfectly represented, the score is displayed along with the sound. As a research method, Laban Movement analysis was used as a motion expression activity program. It is analyzed by four elements of LMA: Body, Effort, Shape, and Space. We observed the connectivity, body structure, body movements, progress, gestures and postures of each part of the body measured by LMA and figured out what the content of movement was. When the anatomical position of the body is divided into upper/lower (vertical) (average: 34/42: total score), left/right (horizontal) (average: 23/42: total score), and front/back (sagittal) (average: 13/42: total score). Through this study, it is shown that the movement of the children with intellectual disabilities can be induced by using the motion graphics and the functional game using Kinect to train the body structure and movement direction in daily life and to induce the change of the internal attitude.
