In the IDW ’24, we are introducing a new “I4D Contest” targeting students from colleges of technology (KOSEN). Outstanding demonstrations will be awarded the I4D Best Demonstration Award.
Colleges of Technology (KOSEN)
Colleges of Technology are higher education institutions for junior high school graduates. There are 58 colleges of technology in Japan, and their excellent education system, known as the “KOSEN education system”, has been highly praised domestically and internationally. KOSEN institutions have also been established overseas, including in Mongolia. KOSEN students actively present their research achievements in academic conferences, and their accomplishments in robot contests and programming contests have attracted media attention.| Date: | December 5, 2024 |
| Place: | Main Hall, Sapporo Convention Center |
| Hours: | Demonstration: 12:30-16:00 Award Ceremony: 17:30-18:00 |
(1) Evaluation Method
The judging will be conducted by an I4D Award Committee. The judges will visit the booths during the contest and evaluate them.

| I4D-1 | Design of AR/VR Optical Systems Based on Micro-lens Array Teshima & Hattori Lab. National Institute of Technology, Sasebo College |
(Introduction Video)
|
| This research aims to establish an optical system that renders images directly onto the retina and conducts optical design and image generation for AR/VR based on microlens arrays. The demonstration uses a display device consisting of a display, a pinhole spacer and a honeycomb-structured microlens array and aims to enable virtual images to be seen at only a few centimeters from the eye. The images on the display consider the overlapping and distortion of the images caused by the microlens array. This optical system is intended for future use in terminals used at a distance close to the eye. | ||
| I4D-2 | Distance Based Rear Mapping on Transparent Film Deluilu National Institute of Technology, Nagaoka College |
(Introduction Video)
|
| This project aims to create an interactive display system that keeps the projected object at a consistent visual distance, regardless of whether the user moves closer or farther from the screen. The system includes a Raspberry Pi, a rear projector, and sensors along a path to detect the user’s position. As the user moves, the projection adjusts dynamically so the object appears to remain the same size and distance, creating the illusion of a stable object. The system receives data from the sensors, calculates it in Unity, and adjusts the camera distance based on the user’s position. | ||
| I4D-3 | Development of an Inexpensive and Interactive Electronic Whiteboard System Using a Web Camera and Projector AR Lab. National Institute of Technology, Kagoshima College |
(Introduction Video)
|
| We demonstrate the development of an original system employing an existing projector and a web camera to build a simple digital whiteboard. For input, we use an original device that combines a laser pointer and a toggle switch. The web camera captures the trajectory of the laser pointer, which is then displayed on the projector. The toggle switch changes the mode to move the trajectory or erase it. The benefit of this system is that it is highly cost-effective and affordable, and we intend for it to be used in small offices and schools. | ||
| I4D-4 | Quantification of Kinesthetic Motion and Power by Using Hand Force Myography Yamamoto Shoji Lab. Tokyo Metropolitan College of Industrial Technology |
(Introduction Video)
|
| To ensure better quality of products, it is important to transfer knowledge and skills in manufacturing. We focus on the skill transfer by figure movements in our research. An EMG sensing has been used in conventional studies to clarify finger movements. However, these are difficult to use for long periods because of sensitivity for sweating and electromagnetic noise. Therefore, we developed a novel sensor that can tolerate in the field. Our sensor measures the pressure generated by the volume change of the arm muscles (FMG: Forcemyography). Based on this change, we can estimate the movement and force of fingers exactly. | ||
| I4D-5 | AR Systems for Visualization of Hemodynamic Changes Using a Stereo Camera Laboratory of Biological Information Measurement Salesian Polytechnic |
(Introduction Video)
|
| Utilizing a general-purpose near-infrared single-lens camera, this system applies for the creation of technologies for the early detection of symptoms like heat stroke which are brought on by changes in blood flow. By building a system with "Nvidia Jetson," this research aims to encourage the broad application of this method. This demonstration proposes a system that uses augmented reality (AR) with a stereo camera and a Jetson to display hemodynamic changes. Furthermore, this research addresses a previous work on a system that visualizes hemodynamic changes by automatically analyzing images taken with a camera that has been adapted for near-infrared imaging. | ||
| I4D-6 | Diverted Corner-Cube Retroreflector (D-CCR) for Projection Screen Under Sunny and Automobile's Conditions Wako Lab. National Institute of Technology, Sendai College |
(Introduction Video)
|
| We will demonstrate a new type of projection screen that can display bright and vivid images even under sunlight or in bright environments. By changing the shape of the Corner-Cube Retroreflector and optimizing the design (Diverted-CCR, D-CCR), the projected image is focused on the viewer and external light that becomes noise is blocked. By this method, it makes possible to display bright and vivid images even in bright environments. As an example of its application, it can be installed on the pillars of a car and used for projection mapping, which can eliminate blind spots and contribute to improving safety. | ||
| I4D-7 | Differences in Gaze Direction of 3D- and 2D- Avatars: from Viewpoint of “Mona Lisa Effect” VISION223 International College of Technology, Kanazawa |
(Introduction Video)
|
| We will demonstrate two contrasting AR effects by employing Meta Quest 3. One is the so called “Mona Lisa effect”; the 2D avatar’s gaze appears to continually track the observer, disturbing perceptual reality. This suggests that 3D avatars, like stereographic image of real faces or 3D-CG faces, are strongly required. This is due to “Leonardo’s paradox”; the 2D projection yielded by binocular fusion, a part of human perception, is geometrically incorrect. The other effect is that artificial information like texts is generally more comprehensible in 2D formats because 2D symbols are created by humans. | ||
| I4D-8 | Personalized Tabletop Illusion Display with Dynamically Adjustable Sweet Spot Kuchii Lab National Institute of Technology, Kitakyushu College |
(Introduction Video) |
| We will demonstrate a personal tabletop illusion display that dynamically adjusts the sweet spot to provide a three-dimensional visual effect from multiple directions. This display overcomes the limitation of conventional optical illusion displays and 3D signage, which only provide stereoscopic effects from certain perspectives, and is one of a number of displays that provide a new visual experience that users can view from any angle. | ||
| I4D-9 | Smoothing Human Movements with Easing Functions Social Creation Laboratory National Institute of Technology, Nagaoka College |
(Introduction Video)
|
| In the process of creating a game or other application, an easing function is used to indicate the degree of motion. The creator must find the function that achieves the ideal movement from among the many easing functions available. This is a very difficult task. Therefore, we developed a system to find an easing function from human movements. The purpose of this system is to reduce the time required to select an easing function by obtaining an easing curve that is close to the hand motion. | ||
| I4D-10 | Aerial Image Display Device with Cylindrical Infinity Mirror Broadcasting Club National Institute of Technology, Yonago College |
(Introduction Video)
|
| We developed the signage device using AIRR (Aerial Imaging by retro-reflection) with a semi-cylindrical infinity mirror and retroreflector. Using a flat infinity mirror, there is a large loss of light and it is difficult to obtain a floating image, but by deforming it into a semi-cylindrical (concave) shape, we were able to obtain a floating image. This method is energy-saving because it can obtain more light spots with fewer light sources. We created a variety of signage by mechanically changing the curvature of the cylindrical infinity mirror, or devising the color and number of light sources. | ||
