Contactless, Effortless - With Just a Camera

Our software uses existing cameras in smartphones and, really, any webcam to see the person or people the app is built for and starts to provide your application with real time information on that user within seconds of starting. 
  HERE ARE THE BASICS
smartphone 1 graphic

Distance can be with a smartphone comfortably held 1-2 feet from the application user.

Illunination

Lighting can vary considerably down to dim conditions with as low as 60 lux of illumination.

Treadmill user 3-5 feet

It can be 3-5 feet if the phone is propped easily or the camera is mounted.

moderate motion

Moderate motion is ok.

 

Hospital with drip stand

Or it can be across the room or, using the back camera, pointed at a person 15-20 feet away.

3-5 seconds

In less time than it takes to get a reading from a digital thermometer, vital signs data is flowing.

Ready for the Real World ...

  • Cardiac Waveform

    Real time pulse pleth modulated relative blood pressure wave form supporting calculation of pulse rate, heart rate variability, and relative blood pressure.

  • Breathing Waveform

    Real time breathing waveform supporting biofeedback, breathing rate, inhale/exhale ratio, breathing amplitude, apnea detection, and respiratory line length.

  • Myofacial Analysis

    Supporting face-point analysis, expression analysis, blinking detection, and talking detection.

  • 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.

  • Continuous or Spot Measurement

    Options for continuous measurements or variable time window spot measurements to support varied use cases.

*** Advanced Applications ***

For specialized measures like absolute blood pressure, electrodermal activity (EDA - sweat),

shock/trauma/compensatory reserve and more...

Here Is The Flow

recent-work-2

1. SDK Integration: Powering Your App

Simple & Flexible – Integrate with just 10 lines of code
 
Step 1: Embed the SDK

Integrate the lightweight SmartSpectra™ SDK into your iOS, Android, or cross-platform app.

Step 2: Connect with the API

Your app sets itself up to make real-time API calls to activate the SDK, control the device camera (and/or microphone, if configured) and be ready to deliver measurements.

Step 3: Configure Output

Choose what biometrics to access and with what frequency (see pricing):
- Heart Rate (HR)
- Breathing Rate (BR)
- Facial Expressions / Stress
- (Optional roadmap: EDA, SpO₂, HRV, blood pressure, etc.)

2. User Experience: Run Your App

Simple & Seamless – No Wearables Required

Step 1: User is seen by camera

Your app will activate the
- Front-facing or rear camera or
- Mounted or room-installed device

Step 2: Real time analysis

SDK checks quality and analyzes the real time video of the user's upper body to extract physiological data using computer vision + signal processing

Step 3: Data flows to your app

Data starts to flow within 3–5 seconds for most metrics

3. Data Output: Create Digital Magic

You control data from there - Powerful, Secure, Private

Step 1: API Returns Data
 
Requested HR, BR, and emotion/stress signals are flowing to your app on the edge
 
Step 2: Your app creates the magic
 
- Display data in-app to users (e.g., dashboards, real time traces, coaching)
- Send data to your backend or cloud
- Integrate with EHR (for clinical or remote monitoring use cases)
- Export to analytics, AI models, or research

What Makes Us So Good?

  • PhDs and more PhDs ... Start with a team with top talent in the contactless sensing fields and smartphone camera design

  • Our own lab facilities ... We run our own lab giving us perhaps the most extensive ML training data sets available

  • We solved the hardest problems first ... Addressing shock/trauma cases makes routine vital sign reporting just a snap

  • Clinical Validations ... We have gone to the most demanding test sites for our clinical and test validations

Frequenty Asked Questions

Can I try this out for myself, on my own smartphone?

Absolutely, click on the INSPIRE button at the top of this page.

Give us a little information so that we can give you access credentials, then we will give you the link to the Apple Store where you can get your free copy.

Yes, that easy.

Can I do this?

Sure you can!

With automated coding tools like Claude Code and the pre-packaged features of the Presage software SDK, your new application for a smartphone, webcam or integrated camera may be as easy as writing a good prompt.

How can I get the code to incorportate into my appliucation?
