The relationship between the objects and mind caused attention and researches in the field of cognitive and human-computer interaction. Riches of evidence on affordance come from the field of neuroscience and behavioral science. On the neuroscience side, studies of brain imaging revealed that when individual was observing an object some cortexes active. For example, in the process of perception of tools’ affordance promoter and parietal cortex activate. And on the behavioral side, compatibility paradigms were used to investigate the issues of affordance. For example, individual with precision grip for small objects responded faster than with power grip. However, the physiological basis of affordance remains unknown. Fortunately, the finding of mirror neurons contributes to explaining the physiological mechanisms of affordance. Mirror neurons refer to the neurons that fire when the animal observe and act the same action as what others perform. These neurons were observed not only in monkey not but also in humans. In humans, the cortexes involving in mirror neurons are premotor cortex and the inferior parietal lobule. The potential relationship between mirror neurons and affordance provide a new view to further answer this question and to understand the physiological basis of the affordance. Further explore more accurate neural basis of affordance from the perspective of mirror neurons is beneficial for us to deeply make sense of the phenomenon of human psychological behavior. Objects do not elicit only one kind of affordance but multiple affordances. An object activates affordance related with grasping or touching (such as object size, orientation) and affordance related to how to facilitate its function. Firstly, different kinds of affordances ranging from structural affordance and functional affordance are introduced. Structural affordance relates to properties of objects that can vary (such as the orientation and angle of an object), and functional affordance relates to properties of objects that keep constant between different experiences of individuals (such as the way to catch a cup). Then, the relations between different kind
