The computer's emerging capacity to communicate an individual's affect raises critical ethical concerns. Additionally, designers of perceptual computer systems face moral decisions about how the information gathered by computers with sensors can be used. As humans, we have ethical considerations that come into play when we observe and report each other's behavior. Computers, as they are currently designed, do not employ such ethical considerations. This project assess the ethical acceptability of affect sensing in three different adversarial contexts, where within each context there are also different kinds of motivations (self-oriented and charity-oriented) for the individuals to perform as best as they can.
