Expression analysis is performed in response to a request for an expression. The expression is related to one or more mental states. The mental states include happiness, joy, satisfaction, and pleasure, among others. Images from one or more cameras capturing a user's attempt to provide the requested expression are received and analyzed. The analyzed images serve to gauge the response of the person to the request. Based on the response of the person to the request, the person can be rewarded for the effectiveness of his or her mental state expression. The intensity of the expression can also be used as a factor in determining the reward. The reward can include, but is not limited to, a coupon, digital coupon, currency, or virtual currency. |
