BioSignals V-18 AI Polygraph System with 3D Camera

Bring physiological recordings and 3D facial movement tracking into the same examination setup. BioSignals V-18 combines a multi-sensor polygraph system, depth camera and integrated ChatGPT AI Assistant to support question preparation and detailed session review.

Integrated ChatGPT AI Assistant

BioSignals brings ChatGPT assistance into the polygraph software workflow. Use case details to help prepare a structured questionnaire and question sequence before the session. After recording, use AI-assisted review to explore the session data and organize observations. The examiner reviews the proposed questions and interpretation throughout the process.

What you can record

• PPG/BVP: records the finger pulse waveform and supports heart rate, inter-beat interval and HRV analysis.
• GSR/EDA: records changes in skin conductance through finger electrodes.
• Skin temperature: adds a peripheral temperature channel for session review.
• Dual respiration: separate abdominal and chest air-pressure breathing sensors.
• Seat movement: an air-pressure seat pad records movement alongside the physiological signals.
• Hand movement: separate left- and right-hand air-pressure sensors.

3D facial movement tracking

The depth camera adds head orientation (yaw, pitch and roll), facial movement and eye-position parameters to the session. The system also provides a camera-based heart-rate estimate from facial color changes. These are additional review channels, not independent conclusions about truthfulness.

Record, review and export

The Windows PC software displays live signals, supports sequential question workflows and saves recordings for later review. Review raw signals and analysis together, adjust session settings and export CSV data for further analysis and documentation.

Technical details

Data transfer rate: 2,400 bytes per second. PPG data supports heart rate, inter-beat intervals and HRV time-domain and frequency-domain analysis.

Setup and compatibility

Windows PC required for initial activation and the main software. Supports BLE and Android OTG connections, with Android and iPhone apps for physiological signal viewing and recording.
