Abstract

The present disclosure relates to a computer-implemented method for monitoring hand movements of a writing instrument's user, comprising: providing an electromyography sensor on the user's wrist or hand; monitoring hand movements of the user during a writing session with the writing instrument by reading sensors of the writing instrument; monitoring hand muscle activity of the user during the writing session by reading the electromyography sensor; correlating hand motion data and hand muscle data obtained from the monitoring; evaluating the correlated data and classifying the hand movements as normal or abnormal based on at least one of tremor parameters, hypokinetic parameters, and historical data of the user; and providing an indication in case of an abnormal evaluation.

Dependent claims

A computer-implemented method for monitoring hand movements of a user, comprising:

providing an electromyography sensor on the user's wrist or hand;
monitoring hand movements of the user during a writing session with the writing instrument by receiving hand motion data via at least one sensor of the writing instrument;
monitoring hand muscle activity of the user during the writing session by receiving hand muscle data via the electromyography sensor;
correlating the hand motion data and the hand muscle data obtained from the monitoring;
fusing hand motion data through a data processing algorithm, wherein the hand motion data has the form of a 3-dimensional vector, wherein the dimensions are position, speed, and acceleration of the writing instrument;
evaluating the correlated data and classifying the hand movements as normal or abnormal based on at least one of tremor parameters, hypokinetic parameters, and historical data of the user;
and
providing an indication in case of an abnormal evaluation.

5 more elements

A system for monitoring hand movements of a user, comprising:

a writing instrument comprising:
one or more sensors configured to monitor hand movements of the user during a writing session with the writing instrument by reading sensors of the writing instrument;
a communication system configured to provide an indication in case of abnormal hand movements;
and
a computer system configured to execute computer-implemented steps for monitoring hand movements of the writing instrument's user, including fusing hand motion data through a data processing algorithm, wherein the hand motion data has the form of a 3-dimensional vector, wherein the dimensions are position, speed, and acceleration of the writing instrument;
and
an electromyography sensor configured to be attached on the user's wrist or hand, wherein the electromyography sensor is in communication with the writing instrument.
