BP can be measured using selfie videos. Could you have ever imagined? No right? But well, it seems like this may be possible. In good news for people who have blood pressure (BP) problems, monitoring BP might one day become as easy as taking a video selfie.
Researchers have tested a technology called transdermal optical imaging. Seems like, this measures blood pressure by detecting blood flow changes in smartphone-captured facial videos.” This study shows that facial video can contain some information about systolic blood pressure.” This was carried out by said researcher Ramakrishna Mukkamala. He is a professor at the Michigan State University.
Ambient light penetrates the skin’s outer layer. As a result, this allows digital optical sensors in smartphones to visualize and extract blood flow patterns. Transdermal optical imaging models can use this to predict blood pressure.
For the study, the research team measured the blood flow of 1,328 Canadian and Chinese adults. Most importantly, it did so capturing two-minute videos using an iPhone equipped with transdermal optical imaging software.
Consequently, the researchers compared systolic, diastolic and pulse pressure measurements captured from smartphone videos. This was done using a traditional cuff-based continuous blood pressure measurement device. Next, the researchers used the data to teach the technology how to accurately determine blood pressure and pulse from facial blood flow patterns.
It’s interesting to note that the device measures BP according to international standards. However, researchers videoed faces in a well-controlled environment with fixed lighting. Hence it is unclear whether the technology can accurately measure blood pressure in less controlled environments, including homes.
Also, the study participants had a variety of skin tones. But the sample lacked subjects with either extremely dark or fair skin. Thus, we can’t tell how successful this device will be. But if it is any good, it’ll be one smart invention!

“A Virtual Lion King Production Process.”
The team behind The Lion King described the making of the film as a “virtual production process.”
Director Jon Favreau told journalists that they aimed to apply the technology used. They wanted live-action filmmaking to the virtual recreation of Serengeti they would develop.
A dedicated team went to Kenya in order to conduct extensive research on the features of the landscapes and wildlife there. A huge number of photographs were taken which would later help the graphics team. The effects team to reimagine that place accurately for a worldwide audience.
The director revealed that AI was used to feed the 3D model of the lion in various scenarios. For scenes like crying or being hungry which were then used in the film, in order to help the computer make a connection between intent and behaviour.
Huge effort and thought go into creating a film like this. Bringing together filmmaking tools and animation in order to create a whole new world.
