How to detect heart pulse rate without using any instrument in iOS sdk?
I am trying to figure out a way to create an iOS app to measure Heart rate but I am unable to get a start on how to proceed with it.
I read that it could be possibly done using accelerometer or using the camera with the flash to see the blood flow( though I dont know how that works).
Would anyone be able to help me with this or point me at a right direction so that I would be able to figure out what to do?
Solution
You should be able to use the camera to measure pulses, and if the phone is held in such a way that there is a lot of light behind the finger that covers the lense then you can even do without flash, or use a phone that has the flash a bit further from the camera (as I do with my HTC HD).
The Instant HeartRate app for various phone has been tested properly (or so I read in an article) and works well, I've tested it on clients (I am a part time PT)- and compared to reagular heartrate monitors and actually found it to be more accurat as it measures faster before the heartrate drops.
As how to make the app, well I assume you will have to access the camera and detect changes in color and calculate the pulse based on the frequency of the change
I havent done this,- but logically it makes sense. I wish you the best of luck, and please share with us your solution :)
