Microsoft had a patent application on a very similar idea: > Television viewing tends to be a passive experience for a viewer[...] To increase interactive viewing and encourage a user to watch one or more particular items of video content, awards and achievements may be tied to those items of video content. [...] Producers, distributors, and advertisers of the video content may set viewing goals and award a viewer who has reached the goals.[...] > Additionally, the viewing behavior may include an action performable by the viewer and detectable by one or more sensors, such as a depth camera.[...] > If the viewing goal has been met, an award may be granted to the viewer. An award may be a virtual award. Such as an addition to a viewer score or an update to an avatar associated with the viewer https://patents.google.com/patent/US20130125161 https://patents.google.com/patent/US20130125161
