Abstract
Disclosed is a digital pen that tracks the user's writing and provides useful feedback based on the user's writing. In one embodiment, the pen may provide feedback when the user has written a misspelled word, invalid mathematical expression, or any noncompliant expression. The pen may also provide feedback relating to the user's handwriting. The feedback may be visual, auditory, or tactile, and may be realtime or delayed. Statistics relating to the user's performance may be tracked, uploaded to external devices, and shared with others. This allows the user and interested parties to track the user's progress over time. The disclosed pen will be useful in educational settings.
Claims20
A system for monitoring the efficacy of a therapy regimen, the system comprising:
- a writing device that creates a writing when in contact with and moved relative to a surface by a user, the writing device includes a handheld housing, a tip coupled to the housing and configured to write on the surface, and a sensor coupled to the housing and configured to capture a digital representation of the writing;
- and
- an external computing device comprising:
- a communication interface electrically coupled to the writing device via a network and configured to receive the representation of a writing from the writing device;
- a memory coupled to the communication interface, the memory configured to store the representation of the writing;
- and
- a processor coupled to the memory and configured to:
- identify a series of characters in the representation of the writing using optical character recognition (OCR);
- generate a series of OCR confidence values, each confidence value representing a degree of similarity between one of the identified characters and a model;
- generate at least one performance metric based on the series of confidence values;
- store the at least one performance metric in association with a user identifier (ID) that identifies the user of the writing device and at least one time index that is indicative of a time the representation of the writing was created by the user;
- generate an efficacy value based on at least the performance metric and a baseline metric;
- and
- a display interface configured to display the efficacy value in association with the user ID.

A method for monitoring the efficacy of a treatment regimen, the method comprising:
- capturing a representation of a writing created by a writing device when in contact with and moved relative to a surface by a user, the writing device including a handheld housing, a tip couped to the housing and configured to write on the surface, and a sensor coupled to the housing and configured to capture a digital representation of the writing;
- receiving the representation of the writing from the writing device at an external computing device via a network communication interface that is electrically coupled to the writing device
- storing the representation of the writing in a memory of the external computing device coupled to the communication interface;
- and
- identifying, by a processor of the external computing device, a series of characters in the representation of the writing using optical character recognition (OCR);
- generating a series of OCR confidence values, each confidence value representing a degree of similarity between one of the identified characters and a model;
- generating at least one performance metric based on the series of confidence values;
- storing the at least one performance metric in association with a user identifier (ID) that identifies the user of the writing device and at least one time index that indicates a time the representation of the writing was created by the user;
- generating an efficacy value based on at least the performance metric and a baseline metric;
- and
- displaying, via a display interface of the external computing device, the efficacy value in association with the user ID.
