BioSignals BLUE Polygraph Lie Detector - PPG + Respiration Belt

Build a polygraph workflow around software, signals and clear questions. Bring case preparation, computer-based recording and camera observations into a structured workflow. BioSignals BLUE Polygraph Lie Detector - PPG + Respiration Belt combines the BLUE USB interface with BioSignals polygraph software and the sensor configuration shown below. Choose a focused sensor setup or a broader combination of channels, then use the software to connect your questions with the physiological information you record. The value of the package is the working system: hardware, the matching software and a repeatable way to prepare, record and review a session. A software-led approach to the session Live signal viewing: work with the physiological signals from the sensors connected to your BLUE interface. Question-based workflow: prepare a sequence, run the session and review the recording in the context of the questions asked. Recording and review: save the session for later inspection and bring observations together when reviewing the data. Webcam observations: include visible eye, mouth and head movements using a standard compatible computer camera. Use your case details to prepare better-organized questions BioSignals recommends the BioSignals Data Assistant by Eldad Wasserman, available in ChatGPT, as an optional aid to preparing a case questionnaire and examination questions. Start with the situation you want to examine, provide the relevant facts, then use the suggested structure as a draft for your own review. Describe the case: outline the situation and the information you need to clarify. Complete the questionnaire: supply the relevant case details and review the context. Prepare a question sequence: use the assistant to help draft and organize questions, then check and edit them before use. Record and review: conduct the session with the selected sensors and review the physiological recording together with the question context. ChatGPT access is separate from the supplied BioSignals software; a paid ChatGPT subscription is not included. Review and adapt the proposed questions before using them. The assistant helps with preparation and organization, while the reviewer remains responsible for interpretation. Facial-movement analysis through an ordinary computer camera The delivered polygraph software includes camera-based observation of visible movements of the eyes, mouth and head. Use a compatible standard webcam to add a visual dimension to the session without purchasing a specialized camera for this feature. Bring these visible movements into your review alongside the physiological recording. This gives you an additional source of context when looking back at the session, using the camera already available on a compatible computer. Your sensor configuration: what it adds This configuration combines pulse waveform and breathing movement. Compare these complementary signals rather than viewing every change through a single measurement. PPG finger sensor Follow the pulse signal during a session. Use it to explore changes during paced breathing, relaxation exercises and different stages of a recording. Respiration belt Make the breathing pattern visible. Follow the rhythm and changes in breathing movement while practicing a breathing exercise or reviewing a question sequence. What arrives with this package One BioSignals BLUE USB interface One USB-A to USB-C communication cable BioSignals polygraph software PPG finger sensor Respiration belt Use the included USB cable to connect the interface to a compatible computer. A computer and webcam are not supplied. Before ordering, contact us if you need help confirming your computer, operating system or an existing sensor connection. Choose the channels you want to observe A one-sensor package is a focused entry configuration. Two- and three-sensor combinations add complementary observations, while the four-sensor package combines pulse, skin conductance, skin temperature and breathing movement. Your choice determines the physical physiological channels supplied with the package. Use the system for appropriate polygraph recording, demonstrations and research workflows. A structured procedure and careful human review remain central to interpretation; physiological responses and facial observations do not independently establish whether a statement is true or false. Choose the package around your work Every BLUE configuration on this page has its own clearly listed sensor contents. The software follows the product family: biofeedback software with a biofeedback package, or polygraph software with a polygraph package.
