Measuring representational motions in a medical context
First Claim
1. A computer implemented method comprising:
- receiving data representing graphomotor motion during a succession of executions of graphomotor diagnostic tasks performed in a medical context by a subject, the graphomotor diagnostic tasks comprising maze-following tasks;
processing the received data using a computer, including determining a first set of quantitative features from a first execution of a task by the subject, and determining a second set of quantitative features from a second execution of a task by the subject;
determining one or more metrics based on a comparison to the successive executions, including using at least the first set of quantitative features and the second set of quantitative features to determine said metrics; and
providing a diagnostic report associated with neurocognitive mechanisms underlying the subject'"'"'s execution of the tasks based on the determined metrics,wherein the maze-following tasks comprise a first maze following task corresponding to the first set of quantitative features, and a second maze-following task corresponding to the second set of quantitative features, andthe second maze-following task is executed after the first maze-following task, and wherein the first and second maze following tasks share a common solution, and wherein the second maze following task has a greater number of decision points in the solution than the first maze following task.

13. A computer implemented method comprising:
-
receiving data representing graphomotor motion during an execution of a graphomotor diagnostic task performed in a medical context by a subject, the graphomotor diagnostic task including one or more decision points; processing the received data using a computer, including determining a first set of quantitative features from the execution of the task by the subject, the first set of quantitative features characterizing the motion in a vicinity of the one or more decision points; processing prior data characterizing motion during one or more prior executions of the diagnostic task to determine a second set of quantitative features from the one or more prior executions of the task, the second set of quantitative features characterizing the motion of the one or more prior executions of the diagnostic task in a vicinity of the one or more decision points; determining one or more metrics based on a comparison to the prior executions, including using at least the first set of quantitative features and the second set of quantitative features to determine said metrics; and providing a diagnostic report associated with neurocognitive mechanisms underlying the subject'"'"'s execution of the tasks based on the determined metrics wherein the first set of quantitative features includes a decision making time in the vicinity of each of the one or more decision points during the execution of the task and the second set of quantitative features includes a representation of a decision making time in the vicinity of each of the one or more decision points during the one or more prior executions of the task. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
