In order to guide a hand to an imaged position of an arm in mid-air, this paper proposes an aerial guide illumination that is formed with aerial imaging by retro-reflection (AIRR). When acquiring a clear image of a hand or an arm in a noncontact way, it is necessary to use a lens with a low F-number. Then, it is necessary for a user to adjust their hand position precisely at the imaged position with non-contact restraint. In order to solve this problem, our propose method utilized the aerial image for guiding the user’s hand. Our previously developed aerial guiding illumination was an aerial flat plane and has problems with precision in the hand position and the depth perception. Since there is a difference in the recognition of the aerial guide depending on the reaching method, reaching experiments were conducted for the aerial guiding illumination. Effectiveness of the aerial guiding illumination has been quantitatively confirmed.
