“…A currently very studied method to create an aerial interface is by utilizing a 2D image reconstructed in mid‐air using optical devices for aerial image formation such as a Fresnel lens, 16 dihedral corner reflector arrays (DCRA), 17 or aerial imaging by retro reflection (AIRR) 18 . This technique reproduces the same 2D image displayed by a standard display in mid‐air upon the real image formation by those optical devices.…”

This paper presents an interactive three-dimensional (3D) touch and gesture user interface that utilizes a light-field display and a 3D sensor. In contrast to conventional gesture interfaces, in which usually the image space and gesture space are separated, a user can directly interact with the 3D image in this interface system. To achieve this trait, the 3D registration between the sensor and display coordinate systems is necessary. In this study, we propose a method to automatically match the position of the reconstructed 3D image with the position of the hand of the user based on scattered light detection. The proposed calibration process is automatic and enables self-calibration during practical operation without laborious measurement work. The method allows us to use the gesture detection capabilities of the leap motion controller to develop an interface where content and gesture positions match. We show some examples of 3D touch and gesture interactions in which the gesture position and the generated content match on a light field display.

“…Several interactive systems based on these mid-air imaging optics have been proposed. Yamamoto et al [7] developed a mid-air display that can be operated with a fingertip by combining the mid-air image display using AIRR and gesture recognition using a high-speed camera. MARIO [8] and Scooplit [9] are systems that display mid-air CG characters using MMAPs and enable interaction with the characters by sensing the behavior of the user.…”

Previously, a telepresence system, called Levitar, was proposed to allow communication through computer-graphics (CG) avatars in real space. Levitar employs micro-mirror array plates (MMAPs) to display mid-air images and optically transfer the camera viewpoint to the mid-air image-display position optically. This system captures the first-person view of a mid-air image avatar; however, it has a limitation that the stray light caused by MMAPs reduces its range. Therefore, in this study, we propose an optical system to capture a wider range of mid-air viewpoints. The proposed optical system uses aerial imaging by retro-reflection (AIRR) instead of MMAPs for mid-air image display and camera viewpoint transfer. AIRR is a mid-air imaging system that includes a beam splitter and retro-reflector. However, in contrast to MMAPs, it does not generate stray light. The optical transfer of the camera viewpoint by AIRR enables the capture of a large area. To evaluate the range of the capturing area when using cameras with MMAPs and AIRR, we conducted experiments under different camera gaze directions and effective angle of view. The results indicate that AIRR maintains a constant resolution up to 40 • of the camera gaze direction, whereas MMAPs have a lower resolution above 30 • , and the area of the marker detection rate of over 80% is approximately 54% larger for AIRR than for MMAPs. This implies that AIRR achieved a wider imaging range than MMAPs for mid-air telepresence systems.INDEX TERMS Avatar, mid-air image, viewpoint transfer, wide imaging range.

“…This visual interface system allows for contactless interaction, making it an appealing solution for addressing concerns related to infection transmission. In the investigation of aerial imaging techniques, the method utilizing retro-reflection, such as the dihedral corner reflector array (DCRA) 6,7) , the ASKA3D plate 8) the AIRR 9) , and the roof mirror array 10), has gained considerable interest, because the advantage of having fewer aberrations, and the absence of a focal length allows for a compact configuration compared to lenses and concave mirrors.…”
