Abstract: 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.

Abstract: In embodiments of calibrating an electronic writing device, an electronic writing device includes a calibration component configured to calibrate writing data to an orientation of a writing surface. To do so, the calibration component determines whether writing data corresponds to a calibration movement. If the calibration component determines that the writing data corresponds to the calibration movement, the calibration component determines a correction angle based on the writing data and stores the correction angle in a writing buffer. The calibration component then uses the correction angle to adjust subsequently received writing data to align the writing data to the orientation of the writing surface.

Abstract: Methods are provided for verifying whether a mobile device is at a site. An exemplary method involves obtaining a location of the mobile device from the mobile device and obtaining a captured value for a machine-readable code from one of the mobile device and the site, the machine-readable code being presented by the other of the mobile device and the site. When the captured value is equal to a reference value for the code, the mobile device is verified as being at the site when the location of the mobile device corresponds to a location associated with the site.
