What do you think about customer feedback through gestures?

I will appreciate your help to validate our MVP (Gestualy). The system is capable of recognizing in real time the gestures of people passing in front of a camera, estimating whether it is a gesture of approval or disapproval and even predicting gender, age and mood. All information inferred in real time is stored in the cloud in order to generate useful reports for businessman or event organizer. Thanks in advance.
