Device IVA-HW100 that can determine handwashing through image recognition using AI technology.
The Ministry of Health, Labour and Welfare recommends a 6-step handwashing procedure for food hygiene, audited by AI (artificial intelligence)! AI handwashing assessment system IVA-HW100.
This product is a system device that automatically determines the correctness of handwashing actions in six steps using AI (artificial intelligence) technology for image recognition. By accumulating learning of the inference model through demonstration experiments with food manufacturers, it assesses the correctness of each handwashing step with an accuracy of over 95% (Note 1). It has established technology that accurately recognizes the use of disinfectants and hand soap, as well as running water conditions, which are considered difficult to detect with conventional image processing. This product is an appliance equipped with a display computer device that has waterproofing for everyday use and is loaded with dedicated software that has undergone AI training. By adopting NVIDIA's AI module Jetson, it enables advanced AI processing and comes standard with a dedicated camera, power cable, and a self-standing support, allowing for immediate operation upon purchase. (Note 1) This refers to the accuracy rate of our inference model's judgments using our evaluation dataset.
basic information
**Main Highlights** - This is a system device that automatically determines the correctness of the six-step handwashing method recommended by the Ministry of Health, Labour and Welfare using AI technology. - The Food Sanitation Act has been amended, making the introduction and operation of hygiene management in accordance with HACCP (Hazard Analysis and Critical Control Points) mandatory. - While the six-step handwashing method is considered effective in food hygiene and its implementation is progressing, standardization and record-keeping remain challenges. - It assesses the correctness of the six-step handwashing method with over 95% accuracy and standardizes it. - It is an easy-to-implement appliance that allows for user authentication, storage of implementation records, and integration with external systems. - A training mode is available to practice the six-step handwashing method. - Messages can be displayed in Japanese and English, and additional languages can be added. It can also be utilized for hygiene management training for foreign employees. (Note 2) HACCP is a hygiene management method in which food business operators identify hazards such as contamination by foodborne pathogens or foreign substances and manage critical processes to eliminate or reduce these hazards throughout all stages from the receipt of raw materials to the shipment of products, ensuring product safety.

Applications/Examples of results
By introducing this product, we will solve the challenges faced by restaurants, food factories, and medical settings, such as preventing missed handwashing implementation/recording and reducing the workload of supervisors, while also contributing to food safety assurance. It is equipped with user authentication features using IC cards and QR codes, and can store handwashing record data, allowing for monitoring records of handwashing processes in accordance with HACCP. It also has FTP network communication capabilities, enabling integration with external systems. Additionally, this product features a training mode that allows efficient practice of the six steps of handwashing with AI. It can display messages in Japanese and English, and additional languages can also be added. It can be utilized for hygiene management education for foreign employees.
Detailed information
-
A system has been developed that recognizes the correct handwashing procedures using AI from footage captured by a 3D camera. Contec has created this system to identify the proper handwashing steps through AI, enabling the recording of correct handwashing practices in environments where hygiene management is essential, such as restaurants, food factories, and medical settings. It can recognize proper handwashing with over 95% accuracy by assessing the cleaning processes and required time for each step in the "6 Steps of Proper Handwashing" recommended by the Ministry of Health, Labour and Welfare.

■AI recognizes the correct poses and procedures for handwashing. The judgment results are visually displayed. We have achieved accurate judgment even in conditions that are considered difficult for conventional image processing, such as with disinfectants, hand soap, and running water. The screen displaying the correct handwashing procedures and methods will visualize and display the handwashing judgment results through AI image processing. This can also be utilized as a learning tool for new workers and in school education for proper handwashing. As a hygiene management tool in accordance with the "Law Amending Part of the Food Sanitation Act," which has been in effect since June 1990, it can be used to verify whether proper handwashing is being correctly implemented in line with the hygiene management method "HACCP."

■Example Configuration of a Handwashing Judgment System Utilizing AI Technology The images from cameras installed for facial recognition and handwashing recognition at the handwashing station are processed by an AI edge computer to determine handwashing compliance. Workers can focus on the handwashing task by following the guidance on the monitor. Additionally, by installing a facial recognition camera at each handwashing space, it is possible to identify the workers. This allows for centralized management of the workers, the time spent on handwashing, and the quality of the handwashing.

By coordinating multiple locations and integrating with core systems, it becomes possible to establish a hygiene management system.
