We present a directional and quantitative input method by clawing key tops, Keyboard Clawing. The method allows a user to input a direction and quantity at the same time without moving his/her hands much from the keyboard's home position. As a result, the user can seamlessly continue typing before and after inputting the direction and quantity. We found that clawing direction is classified using clawing sounds with an accuracy of 68.2% and that our method can be used to input rough quantity.
