Distance perception
Distance perception is the estimation of the distance between an object and one's own body. This assessment can be made with the hearing, see distance hearing , or with the eyes, see binocular vision , or with the skin senses . For example, with the heat and touch sensors of your own face, the distance to another face can be estimated using its body heat and the vibrations of the air you breathe. Likewise, vibrations in the ground caused by approaching steps can provide information about the current distance.
