Paper Abstract

There is a critical need to conduct operational interviews in a wide range of interview and assessment situations, including conventional structured interviews as well as cases in which subjects are unconstrained. Current progress of three advanced prototype instrument development projects looking at non-contact sensing of human physiology to determine the veracity of human communications are presented. These include: 1) Thermal Facial Screening (TFS); 2) Turnkey Remote Assessment of Concealed Knowledge using Eye movement Recordings (TRACKER); and 3) Laser Doppler Vibrometry (LDV). Signals are measured with superior technical quality, in comparison to those obtained with conventional contact methods. Depending on the operational need and the specific context, these instruments can be used as stand-alone techniques or integrated into a multi-modal evaluation of human credibility. Thus, a comprehensive assessment using multiple physiological response systems is possible. A description each technique, the current state of these research efforts, and an overview of the potential for each of these emerging technologies will be provided.
