1. A computer-implemented method for conducting self-administered tests, comprising:
- configuring a touch-sensitive surface of a client device configured to present a computer-mediated, self-administered test to a user and starting the computer-mediated, self-administrated test;
receiving during the test, user inputs on the touch-sensitive surface of a client device and collecting motion data in response to the received user inputs;
generating a trace in response to the received user inputs based on the collected motion data;
determining a set of anchor points of the trace and constructing one or more reference paths for the trace based on the set of anchor points, a reference path connecting one or more anchor points of the determined set of anchor points; and
determining a set of diagnostic features of the trace by comparing the trace to the one or more constructed reference paths, wherein the determining the set of diagnostic features comprises determining a local curvature at the point of the trace, and wherein the determining the set of anchor points comprises comparing the local curvature at the point of the trace to a threshold and determining the point of the trace as an anchor point responsive to determining the local curvature greater than the threshold.

Abstract
The present invention is a system and method to collect and analyze data produced through biometric and psychometric tasks on interactive computing devices. The collected biometric data can be used to quantify motor skills and to generate statistics that correlate with or predict ability in other functional domains. The biometric data tasks and data collection can be incidental to user interaction with a computing device using a touchpad or other input device—such as users drawing lines to connecting screen elements while using the user interface of an application on a computing device.
