In Kognit (2014–2015), we enter the mixed reality realm for helping dementia patients. Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Memory loss is an example. Alzheimer’s is the most common type of dementia. Mixed reality refers to the merging of real and virtual worlds to produce new episodic memory visualizations where physical and digital objects co-exist and interact in real-time. Cognitive models are approximations of a patient’s mental abilities and limitations involving conscious mental activities (such as thinking, understanding, learning, and remembering). We are concerned with fundamental research in coupling artificial intelligence based situation awareness with augmented cognition for the patient.
