In this paper, it suggests how to input what it needs under gesture based which is able to put its text 3 times faster than an existing way with voice based by a person who is a visually impaired person with a smart device that is flat display without a physical button. The suggesting way is a text input method based on gesture that after setting the touch display of the smart phone to 8 directions, then, it inputs number, English/Korean tests and special characters with initial location and central point of input texts following drag motion of the users or it controls and processes all applications in the smart devices naturally. It tries to prove efficiency of this method through real test to the visually impaired.

This study was conducted to estimate the prevalence of ametropias such as myopia and hyperopia from the community based population study. Another purpose of this study was to determine the association between ametropia and nutrient intake. The study subjects was 492 residents over 20 years of age residing in Kuri City. Ametropia was tested based on refrector error using auto referactor. Nutrient intake was estimated from the dietary survey using 24 hour recall method. As a result of data analysis, the prevalence of myopia was 57% and that of hyperopia was 11%. Such a high rate of ametropia prevalence may suggest the increasing risk of eye health in a Korean society. Nutrient intake of myopia group was 5∼15% higher than that of normal group in most of the nutrients. Whereas intake of most nutrient except calcium, retinal, fiber for the hyperopia group was lower than that of normal group. The result may suggest that inbalance of nutrient intake has been related with ametropia.
