Abstract
Teachings of the present disclosure include systems and/or methods for encoding digital data into a handwritten sample. An example method includes: accessing a predetermined vibration pattern stored in a memory corresponding to defined data; and vibrating a stylus based on the predetermined vibration pattern during creation of the handwritten sample to encode the defined data into the handwriting sample.
Claims20
An apparatus comprising:
- a stylus operable to dispense ink on a paper;
- an accelerometer operable to detect motion of a handwriting sample;
- a mass;
- and
- a control circuit to:
- actuate the mass to vibrate the stylus;
- access a predetermined vibration pattern;
- vibrate the mass to vibrate the stylus according to the predetermined vibration pattern;
- sense, via the accelerometer, a movement of the stylus;
- and
- adjust the predetermined vibration pattern based on the movement of the stylus.
