pplkpr's emotion classification algorithm was trained on open data published by academic researchers.
Heart rate variability is based on the balance between the sympathetic and parasympathetic nervous system, which operate at different frequencies.
Can I use pplkpr without a device?
Yes. Just add a report manually whenever you feel something, instead of waiting for the notification.
When does pplkpr notify me?
pplkpr notifies you when it detects heightened emotion, and asks you to report how you’re feeling. It also notifies you when you change locations, to ask if you’ve just left or are about to meet someone. The more you use it, pplkpr will learn to match your patterns.
How does pplkpr know my emotions?
pplkpr is based on measurements of heart rate variability, where subtle changes in heart rhythm signal changes in your emotional state. pplkpr knows when you’re having a strong emotion, and lets you decide what that emotion is.
Where is my data stored, and who has access?
pplkpr stores your data on your phone, so only you have access.
What sorts of actions will pplkpr take on my behalf?
pplkpr can compose text messages, invite people to hang out, or block or delete their contact. These actions will appear on your home screen as they happen.
Which heart rate devices work with pplkpr?
pplkpr has been extensively tested with the Mio wristband, but any Bluetooth LE (also called Bluetooth Smart or Bluetooth 4.0) device that transmits heart rate in real time will work. This includes the Polar H7 chest band and the Zephyr HxM.
Is this a real app or an art project?
It is both. It is a fully functioning app based on scientific research. We are two artists that created it as a provocation, a taste of where we may be heading with our quantified living and algorithmic decision making. It relates to some previous projects we’ve made like us+, Social Turkers, and Conversnitch. We hope that seeing and trying the app will enable people to think critically about this future and speak out about what we do and don't want to manifest.
