| IDEMO-3 | Variable POP Display Which Enables to Change Apparent Shape on Frame Design Kunio Sakamoto1, Anna Kamo1, Karin Ikeda1 1. Konan University (Japan) Related IDW ’25 paper: EPp1-2 |
 |
| POP cards are useful for eye catchings of customers but they are not reusable because of nonrecyclable design. The authors have researched variable imaging board system for reproducting various shapes. We show variable transparent POP display using a polarization control technique and coloring technology. We will demonstrate two types of POP display units (opaque and transparent board), image switching technologies, color generating technologies and polarization control techniques and at I-Demo session.

| IDEMO-4 | Invited UserDetect - Driver Passenger Touch Discrimination Hirohisa Onishi1, John Shanley2 1. Microchip Technology Japan K.K. (Japan), 2. Microchip Technology, Inc. (USA) Related IDW ’25 paper: INP3-3 |
 |
| When used in an automotive environment the touchscreen allows both driver and passenger to select the same items on the panel. User detection provides the option to limit the touch panel from taking input from one or either of the operators. This provided an extra layer of safety and security for functionality such as navigation input, while the vehicle is in motion, or for other inputs such as hazard warning on or off. Indeed, as automotive moves towards hands free driving, and fully automated driving systems, it becomes more essential to have this kind of user detection to ensure that critical systems are operated by the correct user. | ||
| IDEMO-5 | Experiencing Symptoms of Tooth Decay Using Cross-Modal Perception Naoya Tanigaki1, Takeshi Watanabe1, Keiichiro Watanabe1, Kenji Terada1 1. Tokushima University (Japan) Related IDW ’25 paper: 3D8-2 |
 |
| Tooth brushing is important to prevent dental caries. However, it is difficult to maintain motivation. If there is a tool to experience just how painful tooth decay is, it may be useful to motivate to brush teeth to prevent dental caries. Cross-modal perception refers to the sensations created by the interaction of various human senses. We attempted to induce tooth decay symptoms by visual and auditory information from devices such as autostereoscopic display, headphone, and head mount display. We will demonstrate the experience of tooth pain by cross-modal perception (Figure 1). | ||
| IDEMO-6 | Zero-Shot Noise2Noise Denoising for Underwater Image Enhancement Yi-Tsung Pan1 1. National Taiwan University of Science and Technology (Taiwan) Related IDW ’25 paper: IST4-2 |
 |
| Underwater images suffer from complex noise patterns due to light attenuation, scattering, and sensor limitations. And it's difficult to have a clean-noisy image pairs at the same time. How to denoise underwater images without high computing power, or a known noise model, or have a sufficient number of clear quality images is the research goal. In this research, a simple 3-layer network is demonstrated. Modified from Mansour, Y. et. al. , which can quickly achieve improved quality images without any pre-training data or knowledge of the noise distribution, and remove noise at a lower computational cost than conventional research papers. | ||
| IDEMO-7 | A Flat Panel Detector with Computational Pixel Design Enabling High SNR and HDR Haorong Xie1, Weikang Yan1, Kai Wang1 1. Sun Yat-Sen University (China) Related IDW ’25 paper: IST2-1 |
 |
| Previously, a 75µm² 2T1D 256×256 array was trialed, proving its logarithmic exponential operation, high gain and wide dynamic range for low-dose X-ray static imaging, but no dynamic performance due to small scale. Now, a 300µm² 2T1D 0816 512×256 array has confirmed higher gain, plus no tailing and high refresh rate, fitting indirect low-dose online rapid dynamic X-ray detection. Simulations show 2T pixels (removing PD for X-ray direct-conversion materials) work for X-ray direct-conversion, with 3×10âµ single-pixel gain and 0.1MHz max frequency, boasting great potential in direct low-dose online rapid dynamic X-ray detection. | ||
| IDEMO-8 | 3D-OLED Display Peter Levermore1, Rajan Giller1, Ion Forbes1, Daping Chu1, Donal Bradley1 1. Excyton Limited (UK) Related IDW ’25 paper: OLED7-3L |

| Reflective displays (RDs) are quite ecological because of their low power consumption compared with emissive displays. However, the week point was limitation of dynamic range. We demonstrate our newly developed MDR image generation technique suitable for RDs, where the dynamic range is able to be compressed to only approx. 30:1 from HDR images with approx. 10,000:1, that employing only Global-Tone-Mapping (GTM). The dynamic range of hMDR is also 1/3rd compared with conventional SDR or HDR-tone, that employing Local-Tone-Mapping (LTM), where their dynamic range is approx. 100:1. You will be able to observe printed images on A3 paper. | ||

 |
| This demonstration presents a novel Maxwellian optical system that combines a Transmissive Mirror Device (TMD) with our proposed Spherical Multi-Pinhole (SMP). The system eliminates the image loss that occurs during eye rotation in conventional setups, allowing stable and clear image presentation independent of gaze direction. Moreover, owing to the characteristics of Maxwellian viewing, participants with refractive errors such as myopia or hyperopia can perceive sharp retinal images without the need for corrective lenses. The proposed system achieves a wide field of view and shows strong potential for application in next-generation VR/AR display technologies. | ||

| Brushing teeth every day is tough work. To help maintain motivation for tooth brushing, we developed tailor-made tooth brushing training. In the VR space, your own teeth appear right before your eyes, allowing you to learn their shape and where plaque tends to accumulate. You can clearly see the shape of your back teeth, which are difficult to view in a mirror. Furthermore, you can brush your own teeth before your eyes in the VR space (Figure 1). Using this tool may foster a sense of attachment to your own teeth, making you want to brush them every day. | ||

| IDEMO-19 | Optical Design for Super-Multiview Integral 3D Display Hayato Watanabe1 1. Japan Broadcasting Corporation (NHK) (Japan) Related IDW ’25 paper: 3D10-1 |
 |
| We demonstrate a super-multiview (SMV) integral three-dimensional (3D) display aimed at reducing the vergence-accommodation conflict. The 3D display consists of only a display device and a lens array. By optimizing the arrangement of the lens array and elemental image array, the density of the light rays forming a 3D image is increased in exchange for narrowing the viewing zone to only the periphery of the pupils. We also demonstrate a conventional integral 3D display that provides a wide continuous viewing zone covering both pupils. You can experience the difference between the conventional and SMV integral 3D displays. | ||

This demo system consists of a laser light source and a hologram placed on the surface of a contact lens. When the laser light enters the hologram, the recorded image is projected. Since the image is displayed at a distance from the eye, users can focus on it even though the contact lens is positioned close to the eye. In the future, we plan to use electronic holograms to switch images and display videos. | ||

 |
| A two-layer aerial image display will be demonstrated. The conventional aerial display systems require considerable depth and the two-image generation requires two aerial display systems. The new aerial display that we developed can produce a front image (aerial image) and a rear image (light source array) with a flat form factor by use of polarization optical elements. The proposed system is suitable for combining with large LED display panels so that it will be used for outdoor advertisement and ultra large-screen displays at concert halls and stadiums. A small-scale verification system using 8×7 LEDs will be shown. | ||

The demo system is structured as a force input-visual presentation position output system. Users apply force from their palms to load cells to lift and drop objects, and the system uses sensor values to control the movement of the hand object in the VR space. The images are then output to a monitor, allowing users to perceive the weight. In this way, users can experience dynamic changes in weight in real time. | ||

| IDEMO-33 | Developing of Ultra Low Refractive Index Material for Light Guide of AR glass Keisuke Sato1, Daisuke Hattori1 1. Nitto Denko Corporation (Japan) |
 |
| AR-glass is expected to be a next-generation device. Especially, optical waveguide AR-glass which has the properties of lightweight and compact is expected to become mainstream. In AR-glass, Air-Gap part adjacent to the waveguide is essential for keeping the light guide in the waveguide, but concurrently it embraces some issues due to only the Air-Gap. In this time, we developed Ultra-low refractive index layer which is composed by high porosity material. It is effective as a part of the Gap-less type AR-glass by using it instead of Air-Gap. Through this demonstration, we explain about the importance of ULRI material in AR-glass. | ||

The simulator automatically determines the location of the aerial image by use of the positions of the retro-reflector and the light source. During rendering, pixels outside the computed viewing area are excluded to reproduce the appearance of the aerial image in real time according to the observer’s head motion. Using the passthrough function of a VR headset, the virtual aerial image can be overlaid on the real environment for comparative analysis | ||

| IDEMO-37 | Full-Color Holographic AR Effect Display Using Stacked Computer-Generated Volume Holograms Shion Okai1, Hirohito Nishi1, Kyoji Matsushima1 1. Kansai University (Japan) |
 |
| We will demonstrate a holographic AR effect (HARE) display, where three transparent computer-generated volume holograms (CGVH) placed in front of the physical object generate full-color 3D images around the object (Fig.1(a)). Each CGVH having a size of over 10cm×10cm is created from a full-parallax computer-generated hologram (CGH) with approximately 34 billion pixels. Because the CGVHs produce not only parallax but also accurate focus adjustment, viewers can see color 3D images blended with physical objects seamlessly (Fig.1(b)). In addition, HARE produced behind the physical object is natural because of proper occlusion processing. | ||
