Sumiyoshi Kogyo Co., Ltd. (Head Office: Chofu Ogi-machi, Shimonoseki City, Yamaguchi Prefecture; President: Narushi Nakamura), which creates enriched lives for people through town development centered on construction, industrial waste disposal, and real estate development, is pleased to announce that it has developed and newly obtained a patent for its "Skill Instruction System." This system focuses on the "gaze" of construction machinery operators and automatically determines skills and skill characteristics using AI based on recorded data. This system enables multi-faceted analysis and judgment of construction machinery operation skills, which have been difficult to verbalize, and facilitates efficient skill transfer tailored to individual aptitudes. Moving forward, we will propose a new form of skill transfer to address the escalating issues of labor shortages and the aging of skilled workers in the construction industry, thereby contributing to the development of young talent. ■Patent Overview Patent Number: Patent No. 7867735 Patent Holder: Sumiyoshi Kogyo Co., Ltd.
