This paper proposes an input method that enables letter input by applying a handwriting recognition technology even when input by the keyboard or hand writing is difficult. For the proposed system, a foot writing character by changing the position and weight of a load when the user pushes a board with the feet is detected and recognized. The results of the experiment by 10 subjects showed that 82.2% of the desired foot input letters were included in the six output candidates. Using this method a user who cannot touch the touch panel directly or cannot move the pointing device freely will be able to input letters by a slight change of their weight.
