The invention provides a track input device and a track input method. The track input device comprises an attitude sensor (101), a displacement sensor (102) and a processing unit (103), wherein the attitude sensor (101) is used for obtaining the attitude of the track input device (10); the displacement sensor (102) is used for obtaining a movement track of the track input device (10) when the track input device (10) moves on input media; and the processing unit (103) uses the attitude, which is obtained by the attitude sensor (101), of the track input device (10) to correct the movement track, which is obtained by the displacement sensor (102), of the track input device (10) on the input media.
