There is a project done by Human Element Inc./Philipp Schmitt in which somewhat of an intervention is placed at a bus stop. The concept is that while people wait for the bus they engage with a machine that tasks them with things that advance computer knowledge on human behavior. It is not completely an intervention because it is just a machine, people only choose to engage if they go up to it and interact with it. The incentive for people to participate is that they will earn a small amount of money for each minute they spend completely these tasks. The machine may just tell the person to stare into the camera it possesses while it shows different images on the screen. This is so that the computer can obtain information on how the persons expression may change depending on what they are viewing. It is a super interesting idea I think and there are two other parts of the project that also involve collecting information on human behavior for use by computers.
