Abstract Recently most mobile devices have soft keyboards on their LCD touch screens. Because of the tiny size of the touch screen of the soft keyboard, adjacent keys are mistakenly typed. Also utilizing a key for multiple key inputs causes key type errors. In this paper, we proposed an algorithm to recommend proper words to the user while the user continues to type keys, which helps to easily correct key type errors. In addition, we presented a soft keyboard called MissLess which implemented the recommendation algorithm. We evaluated recommendation performance of MissLess keyboard through experiments by using 3 test sets. The test results showed that the success ratio of recommendation reached up to about 90% although there were some differences between results. However it is needed to be considered that we recommended 4 words for an input word in this experiments Key Words : Android, Soft keyboard, Recommendation, Mobile device, Touch screen * 정회원, 한성대학교 컴퓨터공학과 (교신저자) ** 정회원, 한성대학교 멀티미디어공학과접수일자 2013년 10월 11일, 수정완료 2013년 11월 26일 게재확정일자 2013년 12월 13일Received: 11 October, 2013 / Revised: 26 November, 2013 Accepted: 13 December, 2013
