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
A system comprising:
- a housing attachable to a user;
- a mass;
- and
- a control circuit to actuate the mass to vibrate the housing according to a predetermined vibration pattern.
A system as recited in 1, wherein the control circuit is configured to decrypt a signal to access the predetermined vibration pattern.
A system as recited in 1, further comprising a direct current motor to actuate the mass.
A system as recited in 1, further comprising a piezoelectric actuator to actuate the mass.
A system as recited in 1, further comprising a communication interface to receive the predetermined vibration pattern.
A system as recited in 1, further comprising an accelerometer to track movement of the housing;
- wherein the control circuit adjusts the predetermined vibration pattern based on the movement tracked by the accelerometer.
A method, comprising:
- accessing, by a control circuit, a predetermined vibration pattern and
- vibrating, by the control circuit, a mass to vibrate a stylus based on the predetermined vibration pattern during creation of a handwritten sample to encode data into a handwriting sample.
A system as recited in 1, wherein the control circuit includes a system on chip, an application specific integrated circuit, a field programmable gate array, a microcontroller, analog circuitry, or digital circuitry.
A system as recited in 1, wherein the predetermined vibration pattern includes frequency and amplitude variations.
