초록

It is known that one out of every ten people walking down the street is left-handed. In daily living, left-handed people come across hardwares and facilities that were designed for right-handed people. Most tools, utensils, office equipment, home appliances, clothes, medical instruments, sporting goods, weapons, and public facilities are made for the right-handed person. Many left-handed people thus have trouble with living in our environments. In this study, 1,933 Korean male and female subjects aging from 10 to 82 were selected to investigate the various statistics about hand dominance and their employment characteristics of preferred hand in handling diverse products and facilities. The statistics showed that 5.6% were left-handed and 7.6% were ambidexter. There were strong tendency that left-handed people use more left hand when take action that force is required than when take exquisite action. Ambidexter and right-handed people use more right hand when they take exquisite action is required than when take action that force is required. It was found from these results that people use their hands differently depending on the hand dominance when they handle things, hence this should be considered in designing hand control devices.
