OUTLINE……. � � � � � Introduction History Design of Medical Mirror Demonstration of Technology Demonstration of Working Interaction Advantages Conclusion and Future scope Reference

INTRODUCTION Ø Ø Ø Current techniques for physical monitoring require users to strap on bulky sensors , straps etc A new mirror interface for real – time , contact - free measurements of heart rate without the need for External sensors. Users can experiences remote health monitoring by simply looking into the medical mirror ( cardio cam )

HISTORY Ø Ø Invented by Ming - Zher poh in MIT lab in 2009. In 2009 , Ming – Zher Poh and his roommate , Dan Mc. Duff , asked some friends to sit infront of a laptop. He is electrical and medical – engineering graduate student at the 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 Medical lab. Behind the two – way glass , a webcam- equipped monitor is wired to a laptop. His friend Mc. Duff wrote code to process the data in real time which is used to generate an instant heart – rate reading in laptop.

DESIGN OF MEDICAL MIRROR

� � � 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 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 runing the analysis software in real – time.

How does the technology works � � � It uses light to measure the information from your body. Every time to 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 , roomlight or anything that is iluminating your environment. The camera then measures the mono light being reflcted off you , in this case your face.

Demonstration of technology :

WORKING � � � An automated face tracker detects the largest face within the video feed from the webcam and localizes the measurements region of interest ( RIO ) 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 )

Demonstration of working

INTERACTION �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

ADVANTAGES � � � The medical mirror fits seamlessly into the ambient home environment. People can play a more active role in the management of their healthy , as they have complete access to their heart rate. This interface is intended to provide a convient means for people to track their daily health with minimal effort. � This is beneficial for babies or for people with sensitivwe skin or burn wounds.

FUTURE SCOPE � � Creating a real – time , multi parameter physiological measurement platform based on this technology will be the subject of future work. In the future , even your bathroom mirror will be a computer.

WHAT WE CONCLUDE…. � 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 be that probabaly would go understand otherwise.
