The device you're looking at is called the Scanadu SCOUT and, basically, it's a medical tricorder that will give you precise vital information about any human being within seconds, just on contact.
It's very real and it works now. I tried it myself, and knew I was looking at the beginning of a personal health revolution. Star Trek-level stuff. Except it's coming at the end of 2013.
And it's not only SCOUT—the company has two other devices—ScanaFlo and ScanaFlu—which are like having your own medical labs to go. Best of all, those two are so cheap that they are disposable.
SCOUT will not be disposable, though. The unit is a tiny hardware device that reads your vital health information on contact. You simply place it on the left temple and, in less than ten seconds, it will read your pulse transit time, heart rate, electrical heart activity, temperature, heart rate variability and blood oxygenation. Then it sends this information to an app on your iPhone or Android phone, which displays it for you. You can even store your vitals for tracking, which could prove fundamental to many health situations at home.
