Medium-type Korean soft keyboards for smart phones are required currently and are considered an optimized keyboard type that combines a QWERTY-type keyboard, which suffers from small key size, and a 12-key keypad, which require a troublesome input method. In this paper, we will look at the design of medium-type Korean keyboards consisting of 3 rows. The models are classified as having one of the following layouts: (A) a lattice layout with a backspace, (B) a lattice layout with a backspace and a shift (auxiliary) key, and (C) a tilt layout. The models can also be classified as 6-column, 7-column, and 8-column models. The lattice layout of the 7-column model is developed representatively (as a prototype), in which 14 keys for 14 consonants and 6 keys for 10 vowels are arranged. An experiment is performed to obtain the difference in typing times between a QWERTY-type soft keyboard and the proposed model; the p-value of the results is 0.00114. Therefore, the developed model is significantly more effective than the QWERTY-type model. Digits and symbol characters are allocated to the shoulder positions and are accessed using the long-pressing input method.
