Abstract:Recent research evidence demonstrates that the inability to orient oneself and navigate space is an early indicator of Alzheimer’s Disease. The video game Sea Hero Quest (SHQ) was designed to assess the players’ navigation ability, and several research works analysed the SHQ data using simple metrics such as length and time of navigation paths. Expanding these analyses, we propose new performance metrics that capture the geometry of paths, and analyse datasets of more than 60,000 navigators. The metrics identi… Show more
