Abstract
In the ubiquitous society, text information is one of the most important communication methods and a variety of text information are always displayed on cellular phone, navigation system, DTV, etc. Therefore, it is strongly demanded to improve the legibility of text on displays. However, typical design process of fonts for specific devices requires a long development period, whereas print type has been gradually developed in long history. In this paper, considering the gravity center of characters, which makes a large impact to the legibility, evaluation method of gravity center based on potential energy have been proposed. The experimental results show that the potential energy-based gravity center on characters can reflect the position of strokes in silhouette of character and improve the computation accuracy of gravity center on characters.
