Xi Mou

Dr. Mou has dedicated years to optical evaluation and international standardization research in fields such as light health, VR/AR/MR, the Metaverse, and autostereoscopic displays. Currently, she is a researcher at Stanford University and the Technical Director at Hangzhou Santai Testing Technology Co., Ltd. Mou was awarded the 2024 IEC 1906 Award for her significant contributions to the development of international standards for AR display image quality testing methods. She is a registered expert for various international technical committees, including IEC TC110 "Electronic Displays" and ISO TC274 "Light and Lighting," where she coordinates the standardization of health protection for personal display wearables. She has led the development of multiple international standards, such as IEC63145-22-20 for AR image quality testing. Her work, particularly in areas like AR glasses’ ambient light contrast, color gamut, and virtual image resolution, has established internationally recognized evaluation methods. Recently, she has been a key technical contributor to China’s 14th Five-Year Plan, leading the development of new standards for autostereoscopic displays and digital signage.

Tongsheng Mou

Professor Mou at Zhejiang University and a visiting researcher at the U.S. National Institute of Standards and Technology (2009/2010), he is an internationally recognized senior standards expert. His main research areas include photobiology and health, as well as evaluation and international standardization of Virtual Reality (VR/AR).

He is currently a registered expert for several international standardization committees, including "Optical Radiation Safety" (IEC TC76), "Electronic Displays" (IEC TC110), "Audio/Video Equipment" (IEC TC100), and "Light and Lighting" (ISO TC274). He serves as the Chinese national representative for the "Photobiology and Photochemistry" division of the International Commission on Illumination (CIE). As an ISO liaison officer, he coordinates international standardization efforts between ISO TC274 and ISO TC159/SC4 regarding health lighting environments. He is also an IEC liaison officer, coordinating international standards related to light safety and health for electronic display products under IEC TC110 and IEC TC76. In addition, he leads eight international standards projects in areas such as lamp and lighting system photobiological safety, VR/AR, and laser displays, driving the development of new international standards. He is a member of the "Photobiological Safety" group (IECEE CBTL/WG6), promoting unified certification for global optoelectronic products.

In recognition of his outstanding contributions to international standardization across multiple sectors of the optoelectronic industry, he has received the IEC 1906 Award three times (2010, 2015, 2022) and the CIE Outstanding Contribution Award in 2015.

The evaluation and international standardization of Metaverse and Virtual Reality/Augmented Reality (VR/AR) products

This technical seminar will focus on “Evaluation and International Standardization of Metaverse and Virtual Reality/Augmented Reality (VR/AR),” covering measurement methods and evaluation standards for metaverse applications and VR/AR technologies. The talk will explore how to establish unified testing standards to ensure compatibility and reliability of these technologies globally. Additionally, we will introduce the latest work by international standardization organizations, particularly how bodies like IEC and ISO are driving the standardization of VR/AR products in terms of performance, user experience, and safety. Through discussions on relevant evaluation methods, participants will gain in-depth insights into product testing and certification to keep up with the evolving VR/AR technology. The aim of the seminar is to provide participants with the latest information on VR/AR product evaluation and offer practical experience and recommendations to support the advancement of international standardization efforts.
