CogAid is an assistive tool for Workers and Professionals with Cognitive Disabilities. The tool develops AI cognitive assistive tools designed to help workers with acquired cognitive impairments (e.g. resulting from a head injury or stroke) to return to work after rehabilitation and remain employed, particularly in knowledge-intensive work environments. They offer a cognitive assistive aid that helps professional knowledge workers who experience executive function challenges due to cognitive disabilities such as ADHD or brain injury. The cognitive assistive aid supports overcoming challenges by helping a worker increase his or her self-awareness during work situations and by offering personalized interventional strategies, based on the worker’s individual challenges. It aims to provide AI-based cognitive assistive technologies to knowledge workers experiencing temporary or permanent cognitive challenges at work.
