Abstract
Smart phones provide variety of functions like world processing, chatting, web browsing, etc. for users. Therefore, efficiency of the keypad that are used in text entry are becoming more important. But, in traditional english mobile keypad, text entry speed is not efficient because simple placement of characters in accordance with the order of characters. In this paper, we propose the improved english keypad for smart phone using the frequency information of english characters and bigram. And, we verified that the proposed keypad is more efficient than other keypads through the experiment.
