We will exhibit at the HAI Symposium on March 5 (Tuesday) and March 6 (Wednesday), 2024.

Let's learn about the types of the human visual system and eye movements!

We would like to introduce the basics of eye tracking, which we hope will be useful not only for those considering starting research or surveys using eye tracking but also for those who are already using it. This is structured in three parts, so please take a look. In the first part, we explain how eye trackers work. In this article, we cover: - The human visual system - Types of eye movements - Fixation filters We hope this will be helpful to you. *For more details, please refer to the PDF materials or feel free to contact us.

It can enhance the user's immersion.

Eye tracking (gaze tracking/gaze measurement) allows for: ▶ Interaction between humans and computers ▶ Quantification and visualization of attention and interest ▶ Natural behavior of agents For example, it enables a more realistic representation of avatars and virtual characters. It allows for intuitive connections with metaverse users through real eye contact. Characters and environments that can respond to gaze and user interest create an immersive experience. Additionally, it is possible to evaluate UI/UX based on how the system is perceived. For instance, understanding intentions and responding with UX can streamline the interface through intuitive gaze-based interactions. By creating environments that capture user attention and leveraging reactions, smooth UX control can be achieved. *For more details, please refer to the PDF document or feel free to contact us.

A glasses-type wearable eye tracker that can tell where a person is looking.

The Tobii Pro Glasses 3 is an eye tracker that allows subjects to move freely while measuring their gaze. ■ Five Features 1) Recording and Playback on Smartphone Compatible with smartphones (Android), allowing for recording and playback without the need to carry a computer. This makes it easier to obtain a larger amount of data. 2) No Obstruction of Field of View By integrating the LED and eye camera required for corneal reflection methods into the lens, the field of view is not obstructed. 3) Expanded Field of View The scene camera's angle of view has been widened, expanding the vertical and horizontal field of view. It can capture gaze during tasks viewed upward as well as tasks at hand/foot level, allowing for measurement in a natural state. 4) Enhanced Outdoor Measurement Capability By attaching the optional G3 protective lens (for sunlight protection), outdoor measurement capabilities are enhanced. The area for conducting measurements is expanded. 5) Compatible with Helmets Designed to be worn under various helmets. This allows for gaze measurement in diverse environments, making it easier to use across a wide range of professions and research. For more details, please contact us or download the catalog.

"Mobile Research Lab" Tobii Pro Fusion

◢◤ "Tobii Pro Fusion" combines excellent accuracy and precision ◢◤ Like the Tobii Pro Spectrum, which is the highest precision eye tracker, it is equipped with two eye cameras. This allows for a more accurate estimation of the distance to the eyeball, enhancing precision. It can also respond more flexibly to head movements, eliminating the need to require participants to keep their heads fixed or maintain a stationary position. This is a significant advantage, especially in experiments involving children or the elderly. *For more details, please refer to the PDF materials or feel free to contact us.

On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
