BPM phone uses camera to measure heart rate
In Japan, a new category of mobile phones is becoming apparent with functions aimed at elderly users. TechRadar reports.
"A perfect example is the new F884iES, a mobile made by Fujitsu for market-leader NTT DoCoMo's Raku Raku (Easy Peasy) range of phones for OAPs.
The new handset creates a daily health diary for its owner by combining information gathered from two sources built into the phone.
A pedometer measures how far the user walks each day and adds it to data from an ingenious bit of camera trickery.
The phone's camera can be used to measure blood flow in a fingertip pressed to the lens, which translates into an accurate heart-rate reading.
Together, the data are graphed over time, providing a useful, yet simple, tool that could easily be shown to a health professional at a check-up or after a problem has arisen."
