The 1^st Augmented Cognition International (ACI) conference was held in July 2005 in conjunction with the HCI International conference in Las Vegas, Nevada. A full day working group session was held during this inaugural ACI conference to facilitate the development of an Augmented Cognition R&D agenda for the near- (1-2 years), medium- (within 5 years) and long-term (> 5 years). Working group attendees included scientists, developers, and practitioners from government, academia, and industry who were invited to participate based on their numerous years of experience and expertise in the Augmented Cognition and related fields. This article highlights key results of the workshop discussions that were focused on Cognitive State Assessment (CSA) R&D objectives, particularly with regard to the design and implementation of CSA tools and techniques.
