Scoring Cognitive Change Through Sensing and Analysis of Changing Driving Ability

This paper presents a scoring mechanism for the detection of cognitive change in individuals by sensing a high cognition task (driving). The paper identifies scoring algorithms that identify the variations in trips expected within subjects coping with cognitive decline. Trips are compared to a baseline performance set of attributes for the individual and also to gold standard performance (Google routing). Scoring tools are provided to identify subjects that are showing reduced ability or typical compensation techniques. Scoring identifies reduced trip complexity in either number of stops or trip distance and reduced ability to effectively navigate. A scoring tool is also provided to identify drivers experiencing difficulty operating the vehicle safely as indicated by reduced turn signal use. The result is a set of tools that allow a drivers performance to be tracked over time, identifying performance changes for a subject and need for interventions.
