This document discusses the challenges and themes in designing technology for people with cognitive impairments. It notes that cognitive impairments can be caused by conditions present at birth, injury, illness, or aging. An estimated 9.92 million people in North America have cognitive impairments. The document outlines unique challenges in this area of research including developing appropriate design methods, recruiting participants, balancing individual needs vs generalizability, understanding diagnoses vs functional assessments, requiring dual user interfaces, and needing multidisciplinary teams. It discusses themes around perspectives from North America vs other regions and the boundary between assistive and rehabilitative technologies. The primary goals of the workshop discussed are to share best practices, generate new frameworks, and identify differences and synergies between
