Abstract
A system providing various improved perceptions techniques for haptic feedback above interactive surfaces that require no contact with either tools, attachments or the surface itself is described. A range of receptors in a perceiving member which is part of the human body is identified to create substantially uniformly perceivable feedback. A vibration frequency that is in the range of the receptors in the perceiving member is chosen and dynamically altered to create substantially uniformly perceivable feedback throughout the receiving member.
