Abstract: A method includes receiving data representing graphomotor motion during a succession of executions of graphomotor diagnostic tasks performed in a medical context by a subject, 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.

Abstract: Systems and methods are disclosed for detecting tremors in a subject. One method comprises receiving data from a digital device, the data comprising a plurality of digital device positions and a plurality of timestamps, each timestamp in the plurality of timestamps being associated with a digital device position in the plurality of digital device positions. The method further comprises determining a plurality of frequencies of hand movements of the subject based on the plurality of digital device positions and plurality of timestamps. The method further comprises determining a subportion of the data corresponding to frequencies of hand movements above a low tremor threshold, and determining a magnitude of tremors of the subject's hand based, at least in part, on the subportion of the data.

Abstract: A method of determining a cognitive assessment for a subject includes receiving input position data associated with input provided by the subject during a time that the subject is responding to a cognitive test, receiving gaze position data associated with a gaze of the subject during the time that the subject is responding to the cognitive test, and determining a cognitive assessment for the subject based at least in part on the input position data and the gaze position data.

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.
