The present invention relates to character arrangement and an input process of an English 28 alphabet navigational slide input pad and a Korean alphabet function key and navigational input pad. According to the present invention, only desired characters are selected on a free movement screen and can be input in an easy manner as a continuous alphabet (multigraph) function and a navigational slide input function are combined. A multi-movement function of supporting both touch input and navigational slide input by using the free movement screen is a core concept of the present invention. If the navigational slide input function is maximized by using a simple and balanced character arrangement, use frequencies, continuous consonant rings, a moving line (a gesture) connecting characters can be easily reminded. Therefore, locations of consonants and vowels can be recognized in an easy manner. Characters are arranged by ergonomic optimization in harmony with biorhythm. By the navigational slide input, consonants and vowels can be combined in an easy and convenient manner while the continuous consonant rings (multigraph) are input. A number of drawbacks of an existing program are mitigated by supporting split slide input. The navigational slide input is easy, fast, and accurate.
