An apparatus and method for increasing the rate of recognition of spatial writing, the apparatus including an inertia sensor module, a storage module, an operation module, and a recognition module. The inertia sensor module measures acceleration of a spatial writing device. The storage module stores predetermined operation information and parameters for tracing the motion trajectory of spatial writing, and pattern information about the motion trajectory. The operation module calculates a velocity of the spatial writing from the acceleration measured using the operation information and parameters, corrects the calculated motion velocity by limiting positional relationships between predetermined points which correspond to the motion trajectory of the spatial writing, and traces the motion trajectory using the corrected motion velocity. The recognition module recognizes the spatial writing by comparing the motion trajectory of spatial writing traced by the operation module with pattern information about motion trajectories stored in the storage module.
