[A] wearable band that can zap you with electricity is now up on Indiegogo, with its designer hoping to raise $50,000 to develop more features and to begin mass production.
In order to train yourself to stay away from bad habits or continue doing good ones, you’ll need to program the Pavlok app [including] possible software tie-ups such as instructing the wristband to zap you if you send a message to an ex, to beep loudly and embarrass you whenever you step into a McD’s with the help of a navigation app, or to remind you to walk more when paired up with an exercise app.
If you didn’t happen to get the sly reference in the name of the project, check out the article on Pavlovian conditioning on Wikipedia.
