Getting Started

To get started, follow the instructions for one of our currently supported platforms. Each platform has its own integration guide and example applications to help you get up and running quickly. Documentation is available at https://smartspectra.presagetech.com/.

Features

• Cardiac Waveform
  Real-time pulse pleth waveform supporting calculation of pulse rate and heart rate variability.

• Breathing Waveform
  Real-time breathing waveform supporting biofeedback and breathing rate.

• Myofacial Analysis
  Supporting face-point analysis, iris tracking, blinking detection, talking detection, and facial expression classification.

• Relative Blood Pressure Waveform
  Relative blood pressure waveform shape.

• Integrated Quality Control
  Confidence and stability metrics providing insight into the confidence in the signal. User feedback on imaging conditions to support successful use.

• Camera Selection
  Front or rear facing camera selection on iOS or Android and specification of camera input for applications using the C++ SDK.

Model Cards and Limitations

Model cards include:

• Relative arterial pressure waveform
• Heart rate variability
• Pulse rate
• Face analysis
• Breathing rate
• Upper and lower breathing waveforms

Review the SmartSpectra model cards and limitations for metric-specific operating ranges, validation notes, and known limitations.

Authentication

• We support API key authentication for C++, iOS, and Android. We also support OAuth authentication for iOS and Android. See the platform-specific guides for setup instructions.
