Webcams and Telemedicine: New Software Allows Remote Visual Monitoring of Vital Signs
Wednesday, October 6th, 2010I just caught sight of a promising new development going on in a graduate lab at MIT.
When the tools described below are fully integrated into simple virtual meeting interfaces, we really will have many more choices about how we give and receive healthcare support services, won’t we? How utterly exciting!
MIT Team Developing Tool To Monitor Vital Signs Through Camera
A device under development at the Massachusetts Institute of Technology could monitor changes in a person’s vital signs through a low-cost camera, the Boston Globe’s “White Coat Notes” reports (Johnson, “White Coat Notes,” Boston Globe, 10/5).
Researchers led by MIT graduate student Ming-Zher Poh used public-domain software to identify facial positions and to deconstruct the information into red, green and blue portions of video images.
The device then determines an individual’s pulse by tracking small changes in how light reflects off their face as blood flows under the skin.
The tool could be embedded into a mirror or integrated with a Web-based camera.
In May, researchers published initial results from the project in the journal Optics Express.
Early results found that the MIT device identified pulses accurately within three beats per minute, even when up to three people stood in front of the camera and when test subjects moved (Armstrong Moore, CNET News, 10/5).
The team currently is working on refining the device to take other measurements, such as:
* Blood pressure;
* Oxygen saturation; and
* Respiration rate (“White Coat Notes,” Boston Globe, 10/5).
According to Poh, the device’s noninvasive design could make it useful for several purposes, such as monitoring newborn infants or burn victims.
In addition, the device could be used for telemedicine-based health screenings or remote patient monitoring (MIT release, 10/4).
So, what d’you think about them apples?
