Abstract: A software utility that collects a suite of psychobehavioral, neuropsychological, and biometrically relevant data from neuropsychological tests, and from passive and active interaction with a smart device. Passive interaction is a user's interaction that is not explicitly goal directed. Active interaction is explicitly goal directed (e.g., navigating menus, or interacting with an application). This data is used to: 1) provide an objective profile of memory, cognition, perception, motor function, verbal ability, and fluid intelligence; 2) adapt hardware, software, and user interface settings to make informed decisions regarding accessibility options; 3) to detect usage by someone other than the native user of the device, and 4) to provide a unifying protocol (e.g. an API) for the transmission and receipt of data collected from onboard sensor arrays and software—for processing either locally or remotely.
