In embodiments of correcting writing data generated by an electronic writing device, an electronic writing device includes a positional sensor configured to sense movement of the electronic writing device when the device is used to write on a writing surface, and to generate writing data corresponding to the movement of the electronic writing device. The device also includes a correction component that is configured to correct each sample of writing data using rotation data generated by a gyroscope. To do so, the correction component calculates an offset angle of the electronic writing device relative to a reference axis of the positional sensor based at least in part on the rotation data generated by the gyroscope. The correction component then determines a correction angle based on the offset angle, and adjusts the sample of writing data by applying the correction angle to the sample of the writing data.
