Head-Mounted Credibility Assessment Screening System (HMCASS)
HMCASS is a compact, automated tool designed to rapidly assess the credibility of individuals during questioning.
At its core is a state-of-the-art pupillary sensor embedded in an adjustable goggle device, monitoring subtle physiological responses. Electrodermal Activity (EDA) and heartbeat (PPG) are also continuously tracked to enhance confidence in results. Custom software collects and processes real-time data, while an advanced credibility algorithm generates a numeric score indicating the subject’s veracity.
Durable and fast to deploy, the HMCASS fits into a single rugged transit case. Its intuitive operator interface improves speed and ease of use, requiring no highly specialized training and enabling operation across a wide range of environments.
Jointly developed by senior U.S. Government scientists and Azimuth engineers, the HMCASS was purpose-built to meet the portable credibility screening needs of U.S. military, law enforcement, and intelligence community professionals.
