Abstract: A client device is configured to administer unique, equivalent, computer mediated, task versions of a particular task type automatically generated by a task versioning system. Multiple task versions, each comprising of at one stimulus sequence, are generated by performing geometric, symmetric or temporal transformations on the spatiotemporal relationships between one or more stimuli in a task version. Previous user performance may be captured and analyzed to determine a next task version. Task versioning systems with the ability to automatically generate multiple unique, equivalent task versions allow for accurate measurement of neurological, cognitive, and motor skills, by ensuring that learning effects arising from repeated task administrations are eliminated.

Abstract: A client device is configured with a test administration application for conducting self-administered tests. A user interface of the test administration application includes motion restriction regions configured to prevent select types of body motion during particular segments of self-administered tests, and testing regions configured to receive a touch input performed by a specific digit of the user. For example, a touch input involves touching, holding, or tapping a single digit within the bounds of a testing region in accordance with instructions provided by the test administration application. The test administration module records motion data comprising one or more touch events, each touch event describing a touch input performed by the user. Undesired touch inputs that may obscure or degrade the reliability of biomechanical data are identified.

Abstract: A client device is configured with a test administration application for conducting self-administered tests. The user interface of the test administration application includes motion restriction regions for restricting certain body parts from moving or certain body motions during the entire or particular segments of self-administered tests. Only target response motions in a test are captured and analyzed. Undesired motions that may interfere with assessment of users' cognitive and/or motor skills are reduced or excluded. When users' hands are anchored to the device, they will have limited ability to invalidate test results, for example by taking notes or hovering hands over regions of interest in spatial recall tasks. Task administration systems provide improvements in the accuracy and reliability of tests of neurological, cognitive, and motor skills, by ensuring that user inputs to such tests are valid inputs, etc.
