Device rewards you with cryptocurrency when you perform the assigned "body actions. What does this mean? For example, they want to insert captcha challenges into your consciousness so you have to solve them to get your bread money:
>[0035] Furthermore, the task(s) provided by task server 110 can include solving a test for distinguishing human from machine input so that humans but not computers are able to pass it, such as, Computer Automated Program to Tell Computers and Flumans Apart (CAPTCHA) and reCAPTCHA which is a CAPTCHA-like system designed to establish that a computer user is human. The task may require user 145 to solve a verification challenge, for example, but not limited to, an image based challenge including instructions prompting user 145 to solve the challenge through interaction with one or more images.
(The typo - "flumans" (presumably humans) above, appears in the original text but is bizarrely relevant.)
