Method and apparatus for measuring representational motions in a medical context
First Claim
1. A computer implemented method for processing graphomotor motion in a diagnostic task, the method comprising:
- receiving, at a computing device, first data representing graphomotor motion made by a first subject during a first execution of a graphomotor diagnostic task performed in a medical context, wherein the data representing the motion comprises data representing dynamic characteristics of said motion;
processing, using the computing device, prior data characterizing motion made during one or more prior executions of the diagnostic task to determine characteristics of one or more motion element classes;
processing, using the computing device, the first data representing the motion to identify a plurality of elements in the motion, including classifying at least some of said elements according to the one or more motion element classes; and
determining, using the computing device, using the processed first data and the determined characteristics of the one or more motion element classes, a quantitative, qualitative and/or categorical assessment of the first execution of the diagnostic task associated with neurocognitive mechanisms underlying said motion.

Abstract
Disclosed is an apparatus and corresponding method to capture individual representational motions made by a person while performing a neuropsychological test. A user of the apparatus and method may be allowed to view, edit, classify, and retrieve any captured and recorded motions made by the person. In one embodiment, a capture unit, such as a digitizer, captures the motions made by a person while performing a Clock Drawing Test, and the captured data may then be reported in a myriad of ways. The apparatus and method also provide a means to standardize administration and scoring of writing utensil and paper based neuropsychological testing administered to a person or control and test groups for domestic or international applications. By analyzing individual representational motions made by a person while performing a neuropsychological test, unexpectedly more information may be gleaned from the test than was available to physicians from only a completed drawing.

14. Software embodied on a non-transitory computer readable medium comprising instructions for causing a data processor to:
-
receive first data representing graphomotor motion made by a first subject during a first execution of a graphomotor diagnostic task performed in a medical context, wherein the data representing the motion comprises data representing dynamic characteristics of said motion; process prior data characterizing motion during one or more prior executions of the diagnostic task to determine characteristics of one or more motion element classes; process the first data representing the motion to identify a plurality of elements in the motion, including classifying at least some of said elements according to the one or more motion element classes; and determine, using the processed first data and the determined characteristics of the one or more motion element classes, a quantitative, qualitative and/or categorical assessment of the first execution of the diagnostic task associated with neurocognitive mechanisms underlying said motion.

15. A computer implemented system comprising:
-
an input for receiving first data representing graphomotor motion during a first execution by a first subject of a graphomotor diagnostic task performed in a medical context, wherein the data representing the motion comprises data representing dynamic characteristics of said motion; a prior data processing module for processing prior data characterizing motion during one or more prior executions of the diagnostic task to determine characteristics of one or more motion element classes; a classification module for processing the first data representing the motion to identify a plurality of elements in the motion, including classifying at least some of said elements according to the one or more motion element classes; and an assessment module for using the processed first data and the determined characteristics of the one or more motion element classes to determine a quantitative, qualitative and/or categorical assessment of the first execution of the diagnostic task associated with neurocognitive mechanisms underlying said motion.
