There exist many problems in designing a human-to-human communication medium though people recognize the significance of medium as a communication tool. The ''affordance'' theory provided an ecological alternative to cognitive approaches and the concept is popular in the field of user interface design. We extend the concept to cover human-to-human communication and propose the novel concept of ''human affordance,'' which is afforded from humans, not artifacts. We describe the significance of affordance augmentation which creates or enhances mutual understanding in communication by media processing technologies. Also, we introduce two case studies of human affordance; value sharing in text-based communication focused on evaluation differences of the strength of agreement / disagreement phrase, and Electronic Yosegaki (E-Yosegaki) as an N-to-1 communication tool, which enables message communication by hand writing from multiple people to an individual on a tablet computer.
