Pplkpr Tells You Which Friends To Avoid By Analyzing Your Heart Rate
Pplkpr (called People Keeper), a free iOS app, pairs up with any Bluetooth-enabled heart rate monitor and then ranks friendships based on different emotions. The heart rate analyzing app can then do the following for you:
Tell you which friends should be avoided during times of stress
Block people who make you anxious
Send text messages to people who make you happy or calm
Asks if you have left, or are about to meet someone, when you change your location
Below is a prototype of the app in process:
The measurements are based on a metric called ‘heart rate variability’, where even the slightest changes in heart rhythm signal varies in an emotional state. This is then fed into an algorithm to yield the appropriate results.
Pplkpr notifies the wearer when it detects heightened emotion, and asks them to report how they’re feeling. Once the emotion is decided, the app will write text messages, invite people to hang out, or block or delete contacts based on the emotion and the person. You can see all the activity being done by the app on your home screen.
Pplkpr tracks and logs changes in heart rate and, when it notices a shift, asks the user to explain how they’re feeling, where they are and who they’re with. Over time, an algorithm built into the app can then learn which emotions the subtle changes in heart rate relate to.
This makes the app artificially intelligent with time, and has a great deal of benefits psychologically as well. It might just save you a whole series of embarrassment when, in a state of emotional instability, you are about to contact the friend who makes you anxious, but the app prevents you from that.
Moreover, it could help friendships strengthen when it sends a text message to people that make you happy.
“Pplkpr uses GPS and a heart rate wristband to keep track of when you’re coming and going, and when you’re feeling emotional,” said the developers. “[It] implements a complex metric called “heart rate variability… which is correlated with the people you interact with to determine who should be auto-scheduled into your life and who should be removed.”
For people who don’t have a heart rate monitor, the app also lets them add manual emotional readings.
Lauren McCarthy and Kyle McDonald from Brooklyn came up with the app to explore quantified living in relationships, and how people interact.
