The document describes the Medical Mirror, an invention by Ming-Zher Poh at MIT in 2009. The Medical Mirror uses a webcam and two-way mirror installed in a frame to non-invasively measure a person's heart rate when they look at their reflection. It works by detecting subtle light absorption changes caused by blood flow with each heartbeat. The mirror provides real-time heart rate readings and has advantages over traditional sensors by being contact-free and fitting seamlessly into the home environment to conveniently track health. Future work aims to expand its physiological monitoring capabilities.

3. • A new mirror interface for real-
time, Contact-free measurements
of heart rate without the need for
External sensors .
• Users can experience remote
health Monitoring by simply
looking into the medical
mirror(cardio cam).
• Current techniques for physiological
monitoring require users to strap on
bulky sensors, straps etc.

4.  Invented by Ming -Zher poh in MIT Media Lab in 2009.
 In 2009, Ming-Zher Poh and his roommate, Dan McDuff, asked
some friends to sit in front of a laptop. He is electrical and medical-
engineering graduate student at the Massachusetts Institute of
Technology (MIT), was trying to transform the computer’s webcam
into a heart-rate monitor.
 After one year, there was a large framed mirror sits in the MIT
Media Lab. Behind the two-way glass, a webcam-equipped monitor
is wired to a laptop.
 His friend McDuff wrote code to process the data in real time which
is used to generate an instant heart-rate reading in laptop

5. • Medical Mirror to provide a natural user Interface.
• 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 user is visible to the webcam and the LCD monitor is 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.

8. • A single user will be able to interact with the mirror at a time.
• When looking into the mirror, the user will see a box appear
around his/her face and a timer will be displayed on the top corner
of the box.
• Users will be asked to stay relatively still as the timer counts down.
• User’s heart rate will be displayed on the mirror.
• The heart rate measurement will be updated continuously until the
user looks away.

9. •It uses light to measure the information from your body.
• Every time your heart beats, the blood in your vessels
increases very slightly.
• Blood absorbs light and so this increase absorbs more
mono light, decreasing the amount of light being transmitted or
reflected by your body.
• In this case were just using the ambient light around you:
sunlight, room light or anything that is illuminating your
environment.
• The camera then measures the
mono light being reflected off you, in this case your face.

11. • An automated face tracker detects the largest face within the video
feed from the webcam and localizes the measurement region of interest
(ROI) for each video frame.
• It uses light to measure the information from your body.
• The raw RGB signals are decomposed into three independent
components ( patterns) using independent component analysis.
• The user’s heart rate is quantified as the frequency that corresponds to
the highest power of the spectrum within an operational frequency band
(45-240 bpm).

13. • The Medical Mirror fits seamlessly into the ambient home
environment.
•People can play a more active role in the management of
their health, as they have complete access to their
heart rate.
• This interface is intended to provide a convenient means for
people to track their daily health with minimal effort.
•This is beneficial for babies or for people with sensitive
skin or burn wounds.

14. In conclusion, this is an amazing invention
because the relationship between the Medical
Mirror and people could save some people some
discomfort when they visit the doctor and it
possibly could help others save their lives by
noticing the higher heart beat that probably would
go undetected otherwise.

15. •Creating a real-time, multi parameter
physiological measurement platform based
on this technology will be the subject of
future work.

16.  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.
 This interface is intended to provide a convenient
means for people to track their daily health with
minimal effort.
