1 : THE MEDICAL MIRROR Presented by: Chanda bakshi M.Sc(cs)-2NDsem 20121610017
2 : Introduction Digital medical devices promise to transform the future of medicine with their ability to produce exquisitely detailed individual physiological data. Access and control over their own physiological data, they can play a more active role in the management of their health. Current techniques for physiological monitoring typically 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 have the experience of remote health Monitoring by simply looking into the medical mirror(cardio cam).  
3 : history Medical Mirror is invented by Ming -Zher poh in MIT Media Lab in 2009. He won the award in 2011. 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, was trying to transform the computer’s webcam into a heart-rate monitor. He hoped that his software would allow doctors to check the vital signs. After one year, a large framed mirror embedded with a more refined version of Poh’s system 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.
4 : features Diagnose and treat illness Understand patient’s overarching goals Anticipate future problems Understand contextual risks and perceptions Provide contextual information Enhance efficiency and appropriateness of care Augment public health Manage conflicts and burden of multiple recommendations Access and initial triage of symptoms Avoid over- or under treatment Supply decentralized source of local health care
5 : DESIGN 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 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
6 : DESIGN OF THE MEDICAL MIRROR
7 : How does this technology work?? 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.
8 : Demonstration of technology
9 : working
10 : 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 using independent component analysis. The power spectrum of the component containing the strongest blood volume pulse signal is then computed. 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).
11 : advantages The Medical Mirror fits seamlessly into the ambient home environment. This interface is intended to provide a convenient means for people to track their daily health with minimal effort. You could also use it on a phone or laptop or any device that has a camera. The Medical Mirror uses imaging software to measure a person’s vitals, from respiration and pulse rates and blood-oxygen to blood pressure. The medical mirror can also transmit important health information to your doctor via email, which is much easier then planning for an appointment. If the mirror is used regularly, it will build an information-rich personal health profile.
12 : conclusion 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.  
13 : Future scope In the Future, Even Your Bathroom Mirror Will Be a Computer. After that future , ipad will be a bathroom mirror.
14 : Any query ???
15 : thanks
