An Indian-American Invents the Pavlok Wristband

An Indian-Indian man invented a wristband by nudging people to wear it to finish work on time, and to keep giving moderate electric shocks if they can't reach their fitness goals or miss deadlines.

Pavlok, a device invented by Maneesh Sethi, is based on positive reinforcement and attempts to change user behavior. The $250 device is likely to be launched later this year. Sethi, who hired a woman to give him a slap in the face and publish it on the Internet, became popular. Every time he blindly opened Facebook, he said that the bracelet began with punishment for bad behavior and moved to positive feedback for good behavior. Users can program bracelets to change habits and open fewer tags from their web browsers.
The Pavlok user assigns himself a goal, then selects "referee" and gets a text message at 7 pm to check in every day. If the user hasn't finished their goal, they get a shock through the bracelet and through the application. If they complete their goal, they will be rewarded.
