    • 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.
    • Claim:
      1. A method comprising: i) producing an acoustic field from a transducer array having known relative positions and orientations; ii) defining a plurality of control points wherein each of the plurality of control points have a known spatial relationship relative to the transducer array; iii) assigning an amplitude to each of the plurality of control points; and iv) moving the plurality of control points within the acoustic field while adjusting the changes experienced within the acoustic field so that the changes fall under a predetermined threshold.
