This study was conducted to develop wearable products with visual and auditory feedback aimed at promoting
exercise interest in children. Here we determined the theoretical characteristics of cognitive and motor function
development during childhood, empirical characteristics of children's motor functions, and factors that encourage
exercise using natural observation and in-depth interview research methods. The questionnaire assessed children's
motor ability, intensively trained body parts in sports programs, types of training or classes that improve the motor
ability of each muscle group, significantly considered aspects of children's sports programs, and factors that promote
children's interest in exercise. Our results suggest that the development of sport programs comprising varied exercise
options that enhance body and limb movements are needed for balanced growth. Furthermore, it is very important
to provide motivation for regular exercise and appropriate feedback, such as praise and encouragement, to maintain
interest in exercise. This study identifies the standards for developing products that peak children's interest in
exercise and the basis for a physically and mentally healthy society.
