The 21st century has seen that interaction mode and experience value have become the key factors for improving the product competitiveness. Generalized interaction involves not only the traditional human-computer interaction, but also the person-to-person interaction triggered by the products. Traditional product interaction design mainly focused on the practical function of physical dimension and on the use-pattern of behavior dimension.

Giving priority to the humanity value and the social effect is the value orientation of generalized interaction design.
