Introduction
ordinary people start to have access and control over their own physiological data
they can play a more active role in the management of their health
physiological monitoring typically require users to strap on bulky sensors, chest straps or sticky electrodes
This discourages regular use
propose a new mirror interface for real-time contact-free measurements of heart rate without the need for external sensors.
It was recently presented at the SIGGRAPH 2011 Emerging Technologies program.
Design
designed the Medical Mirror to provide a natural user interface.
utilized an LCD monitor with a built-in webcam to provide an interactive display.
A two-way mirror was fitted onto the frame to present a reflective surface for the users in normal lighting conditions
the LCD monitor and webcam
are not
visible to the user
webcam and the LCD
monitor can be used
to project information onto
the reflective surface of the
mirror.
The monitor
and webcam are connected to
a laptop running the analysis
software in real-time
Technology
combining techniques in computer vision and advanced signal
an automated face tracker detects the largest face within the video feed from the webcam
localizes the measurement region of interest (ROI) for each video frame.
The
ROI is then separated into the three RGB channels and spatially
averaged over all pixels to yield a red, blue and green
measurement point for each frame and form the raw RGB signals
working
The webcam in a monitor captures the changes in the light reflected off the subject’s face
The computer translates the light data into a heart rate reading.
Here we use bland design programming language
developed an algorithm that could pick out the heart rate’s light pattern from all the other reflected light captured by a webcam
Conclusion
This project illustrates an innovative approach to pervasive health monitoring based on state of the art technology.
The Medical Mirror fits seamlessly into the ambient home environment, blending the data collection process into the course of our daily routines.
For example, one can envision collecting health data when using the mirror for shaving, brushing teeth etc.
