The Hong Kong Polytechnic University and OPTICAL 88 announced initial results of artificial intelligence diabetic retinopathy screening

In an effort to alleviate the burden on public primary eyecare departments, The Hong Kong Polytechnic University (PolyU) and OPTICAL 88 have pioneered a diabetic retinopathy (DR) screening project. This project is part of the "Smart primary healthcare and eyecare service: From data to algorithms and real-world solutions," supported by Prof. Mingguang HE, PolyU Chair Professor of Experimental Ophthalmology at the School of Optometry. Prof. He, also a Global STEM Scholar under the Global STEM Professorship Scheme and Henry G. Leong Professor in Elderly Vision Health, has developed a low-cost, portable, self-testing retinal fundus camera integrated with a bespoke artificial intelligence (AI) system. This innovation has been tested on 320 eligible individuals, demonstrating an impressive accuracy rate of nearly 90% in detecting referable DR. Of these, 13 positive cases were identified, with 5 confirmed as diabetic retinopathy after further evaluation by ophthalmologists. The team has conducted telephone interviews and surveys to assess the diagnostic accuracy, efficiency, and practicality of the system, aiming for broader implementation across Hong Kong. Fundus Screening of 50 to 59-year-old Saw Success Rates of Up to 97% The research team conducted DR screening for eligible personnel across OPTICAL 88 outlets at Cityplaza, Telford Plaza, and The Optometry Clinic at The Hong Kong Polytechnic University. During the examination, a shot of either eye clearly showed the participant’s fundus, which were graded for risks of diabetes. Success was classified as det ection within 3 shots. The study saw that the screening resulted in nearly a 90% success rate; 100% for participants under 50 years old; 96% for those aged 50 to 59 years old; and 69% for participants who are 70 years old or above. Evidently, the success rate declines with age. 11% of participants saw unsuccessful fundus photographs; while more than half of the participants suffered from small pupils or cataracts. Nearly 30% of participants were unable to obtain gradable fundus photographs within 3 shots; and about 10% of participants were unable to take the photographs due to their inability to focus on the target within the fundus camera. 13 positive cases were identified during the screening: symptoms were found in their fundus photographs. 5 participants were diagnosed with DR after further examination by the research team at the School of Optometry at The Hong Kong Polytechnic University. AI Fundus Screening: Simple & Convenient – Enhance Optometrists’ Efficiency and Public Awareness of Optical Health Ho Kai Wing, OPTICAL 88 Registered Optometrist (Part I) involved in the project, says “The performance of the AI DR screening was exceptional. Compared to traditional DR screening, the AI version is simpler, faster and accurate – thus more appealing to those who may be less aware on ocular health. Pupil-diluting eye drops aren’t necessary for the screening, and the process can be done through the AI system at the optical shop to ensure early detection. He adds, “Optometrists recommend everyone should undergo a comprehensive eye examination once a year to ensure early detection on eye diseases. However, awareness for ocular health is still low in Hong Kong. The latest AI DR screening system hopes to not only increase the quality and efficiency of the work of optometrists, but it also educates the importance of regular comprehensive eye examinations.” AI Portable DR Camera Improves Primary Eyecare in Hong Kong Expanding the Network of Small and Low-Cost Self-Service Optical Screening In addition to convenience for patients and eyecare professionals, the AI DR screening system is also cost-effective. Each screening takes only 5 minutes, a substantial reduction from the 30-minute traditional DR exams. The AI DR screening can process 2000 patients every month, while the latter can only process approximately 400. The former only costs 46% of the traditional method. To process 1000 patients, for example, the traditional exam requires approximately 2 months; while the AI DR screening needs only 10 days, meaning the screening of 1.5 million Hong Kongers aged 65 or above would only take 3 years, rather than 20 years in the traditional method. Prof. Mingguang HE, PolyU Chair Professor of Experimental Ophthalmology of the School of Optometry, says his DR screening method combines technology and AI to solve 3 major issues in optical screening, thus realising the possibility of conducting optical screening in general outpatient clinics and optical shops. First, the small and low-cost cameras have reduced the cost issues for clinics. Second, the self-service screening process reduces dependency on technicians. Third, the AI diagnostics technology aids technicians in producing timelier and more accurate reports. Looking forward, AI diagnostic technology will not only be able to assist in the diagnosis of diabetic retinopathy, but also help diagnose a wider range of eye diseases, and offer specific treatments, thereby making these screenings more accessible, affordable and accountable. Mr Joshua S. Kanjanapas WONG, Executive Director & Co-CEO of OPTICAL 88 says, “Helping our customers to maintain good eye health  is the top priority at OPTICAL 88. We have joined hands with The Hong Kong Polytechnic University to launch the AI DR screening research project with the aim to not only enhance the quality of our professional eye examinations, services and products, but to also promote primary  eye care in Hong Kong. The project can screen out patients with DR signs in a timely manner, so they can seek for medical consultation and treatments when necessary. This project had also collected useful data that can be used to evaluate the benefits of AI technology in primary eyecare. It can also promote the usage of self-service eye health screening tools, and provide insights for the future development of technology in eye care.”   AI Diabetic Eye Screening Research Programme Programme Date: March 1 – April 12, 2024 Candidate Eligibility: 50 year old or above; 18 year old or above with diabetes who hadn’t conducted an eye exam in the past 12 months Participants: 320 Participants’ Average Age: 60.9± 8.3 years old Participants’ Age Range: 32-89 years old Screening Details: Participants were tested for the risk of DR via an AI fundus camera. Results were available 1 minute after test completion. Optometrists then conducted vision tests and explained the results to the participants, who were referred to a specialist or general practitioner for follow-up shall further investigation or treatment was required.   ***END***

PolyU researchers introduce pioneering metaverse-enabled expressive arts therapy programme to foster empathy in adolescents

Innovative technology continues to drive educational transformation, not only enhancing the teaching experience and its effectiveness, but also providing support for students with diverse learning needs. An interdisciplinary research team from The Hong Kong Polytechnic University (PolyU) has designed an expressive arts therapy programme utilising metaverse and virtual reality technologies to foster empathy and self-expression among adolescents, thereby improving their social skills and mental well-being. Led by Prof. Eric CHUI, Chair Professor and Head of the Department of Applied Social Sciences; Dr Grace NGAI, Associate Professor of the Department of Computing; Dr Richard LI, Assistant Professor of the Department of Applied Social Sciences and the Department of Computing; and Dr Peter NG, Assistant Professor of the Department of Computing and the Department of Rehabilitation Sciences, the research team collaborated with Sheng Kung Hui (S.K.H.) St. Christopher’s Home to provide an eight-week therapy course for 30 adolescents aged between 12 and 18 from March to December 2023. The course was delivered by a licensed expressive arts therapist online via a virtual platform on a one-to-one basis. Through virtual reality technology, the course enabled the expressive arts therapist and the adolescents, who were situated in different locations, to engage in real-time interaction and collaborate in three-dimensional art creation based on a variety of themes. During the course, adolescents created their own personalised virtual avatars and made use of a wide range of virtual tools for their artistic expression, while the therapist provided guidance and support to them on how to express themselves and understand the feelings and thoughts of others, through art. The research team surveyed the participating adolescents before and after the course. They found that over 70% showed significant improvement in empathy, with a nearly 40% increase in their scores in relation to interpersonal response, while older participants exhibited greater progress. The findings indicate that the course is effective in fostering adolescent ability to imagine and understand the perspectives and situations of others. Meanwhile, assessments from the art therapist further revealed more than 70% of participants were willing to open up and share their emotions during the course, while almost half of them engaged in self-exploration and self-reflection. The research team concluded that, built upon metaverse and virtual reality technologies, this novel platform for art creation allows adolescents to freely present their thoughts and feelings, while a virtual environment provides them with a sense of security which facilitates closer and more comfortable interaction and communication between them and the therapist. Positive feedback was also received from the adolescent participants who said that they were delighted to be exposed to a new way of creating art and to gain a better understanding on how to build positive relationships with others and the community. They were also excited about participating in similar innovative programmes in the future. Prof. Eric Chui believes that, with ever-evolving social needs and technological advancements, social workers have the responsibility to stay updated on relevant technology so as to be able to offer innovative and timely services. This programme is evidence of an innovative and successful use of metaverse technology in the development of adolescent mental well-being, while also illuminating the potential of educational innovation. He added that the younger generation in Hong Kong is facing numerous pressures, and therefore any method encouraging them to share and relax is worth the social welfare sector exploring. Ms Kiann WONG, registered social worker at S.K.H. St. Christopher’s Home, said that this innovative programme has been profoundly beneficial to the growth of adolescents, allowing them to explore new technologies like the metaverse and virtual reality, and to learn about the importance of empathy. She hoped to continue collaboration with PolyU and provide more innovative learning opportunities for young people. With an aim of supporting a broader range of communities in need, the research team intends to fine-tune the design of the course based on the experience and findings from the programme and expand it to a more diverse audience base, especially including adolescents with special educational needs or facing behavioural and other mental difficulties.   ***END***

PolyU and Diocesan Girls’ School establish AI Swimtech Laboratory, developing biomechanical training to enhance swimmers’ performance

A team led by Dr Billy SO, core member of the Research Institute for Sports Science and Technology (RISports) and Assistant Professor of the Department of Rehabilitation Sciences at The Hong Kong Polytechnic University (PolyU), is committed to enhancing the performance of swimmers by integrating sports technology with biomechanics. By employing advanced wearable sensors and an underwater camera system, the team captures and analyses data on swimmers’ start jump motion and swimming postures, including body movement and muscle activity, thereby assisting coaches in designing training programmes for athletes. The student swimming team of the Diocesan Girls’ School (DGS) is currently adopting these biomechanical training methods into their routine training with the aim of achieving greater effectiveness. To catalyse joint research in the fields of sports science and technology, PolyU RISports and DGS have entered into a Memorandum of Understanding to establish the “PolyU-DGS AI Swimtech Laboratory”. Under the agreement, DGS will provide swimming facilities, where PolyU researchers will install equipment for data collection and will arrange student swimmers to participate in a research trial. This collaboration aims to strengthen research on enhancing elite athletes’ performance and talent identifications by more fully unleashing their potential, thereby maximising athletic performance at school level and nurturing more outstanding swimmers for the local community in the long run. It also aspires to promote STEM education and foster a culture of innovation and technology on campus. Prof. Christopher CHAO, PolyU Vice President (Research and Innovation) remarked, “In recent years, Hong Kong’s ‘flying fishes’ continue to shine on the international stage. The integration of technology in athletic training not only more effectively unlocks their potential, but also helps them achieve notable results. PolyU is committed to the translation of research outcomes and so is delighted to collaborate with Diocesan Girls’ School to enhance their student athletes’ competitiveness. We believe that students can gain valuable immersive learning experiences by participating in research work, which helps cultivate their interest in innovation and technology, as well as develops knowledge in mathematics, science and engineering.” Mrs Stella LAU, Headmistress of DGS stated, “Diocesan Girls’ School, a school with over 160 years of history, has been at the forefront in promoting innovative technology education in recent years. Today, RISports team from PolyU is collaborating with our swimming athletes to put their research achievements in artificial intelligence and biomechanics into practice. Not only will this empower our student athletes to excel in their swimming performance, it will enhance our students’ practical application capabilities in sports science as well as their problem-solving skills using artificial intelligence. This project better equips our students for today’s vast innovation and technology-driven world.” Each subtle movement can be the key to victory in competitive swimming, especially in short course competition. With this in mind, Dr Billy So aspires to develop systematic biomechanical training and explore its effectiveness in enhancing swimmers’ performance. The key findings of his research are as follow: (1) Start jump motion analysis The start jump in swimming demands precise timing, speed and angle of both the jump and entry into the water. The team places patches of a surface electromyography system on athletes’ lower limbs to capture start jump motion. With the use of a reaction time start board and video analytics, the system also provides immediate data on jump reaction, entry angles and speed, to assist swimmers in promptly adjusting their start jump posture. Approximately 30 DGS swimming team students were invited to participate in a six-week training programme, employing this system during 50-metre freestyle swimming practice twice a week for 20 minutes per session. The participants are found to have improved their performance by an average of 0.127 seconds on start jump. By utilising the system to compare and analyse the start jump reaction of participating athletes before and after training, the results show that their average reaction time improved by 0.127 seconds. With the use of surface electromyography system, a reaction time start board and video analytics, the system captures start jump motion with a view to assisting athletes in promptly adjusting their posture. (2) Propulsive force analysis The propulsive force in swimming originates from stroking and kicking, while the stability of core muscles aids in increasing the propulsive force generated from these movements. The team employs an underwater surface electromyography system and a tethered swimming testing system to analyse the propulsive force generated by athletes during swimming. This helps coaches adjust athletes’ techniques and develop suitable training to enhance swimming performance. Approximately 30 student athletes from PolyU and local sports organisations participated in an eight-week muscle training programme focused on core stability. The two systems were then employed to evaluate the athletes’ performance in utilising core muscles during swimming and the propulsive force generated. The results indicate that the average swimming propulsive force generated by the participating athletes increased by about 10%, while their speed in the 50-metre freestyle improved by 0.02 to 0.03 metres per second. Employing an underwater surface electromyography system and tethered swimming testing system helps the team analyse the propulsive force generated by athletes during swimming. This aids coaches in adjusting athletes’ techniques and developing suitable training to enhance swimming performance. (3) Muscle activity analysis The team uses waterproof wearable surface electromyography sensors and an underwater camera system to capture muscle activity of swimmers’ arms, shoulders, legs and trunk during start jumps, strokes and turns in freestyle swimming. The system will be tested in the swimming pool at DGS with the participation of its elite student swimmers. Looking forward, the team will collaborate with PolyU’s Department of Computing to integrate video motion analysis and wearable motion inertial sensors to leverage the collected data in developing a novel artificial intelligence model, thereby further enhancing the accuracy of the system. The team has employed waterproof wearable surface electromyography sensors and an underwater camera system to capture muscle activity of swimmers during freestyle swimming. The graphic shows the muscle activity pattern.   ***END***

PolyU develops and manufactures space instruments for the Nation’s Chang’e-6 mission, successfully completing the first lunar far side sampling in human history

In support of the Nation’s landmark sample return mission from the far side of the moon, a research team at The Hong Kong Polytechnic University (PolyU) collaborated with the China Academy of Space Technology (CAST) to develop and manufacture the “Surface Sampling and Packing System” for this historic task. On June 3, the PolyU-developed system accomplished the tasks of automatic sample collection and packaging on the lunar surface, following the soft landing of the Chang’e-6 probe, marking a milestone in human space exploration. The probe has already taken off from the moon with the cargo of the first-ever lunar soil samples from the far side set to return to Earth on June 25. Prof. Christopher CHAO, Vice President (Research and Innovation) at PolyU, congratulated the research team on their outstanding achievement, and said, “With over 30 years of experience in deep space research, PolyU is the only university in Hong Kong that has participated in various national space projects. We feel honoured and grateful for the Nation’s continued trust and support in our research endeavours. We look forward to leveraging our expertise and collaborating with researchers in the Mainland to make meaningful contributions in national space missions.” Commenting on Hong Kong’s contribution to the national space mission, Prof. YUNG Kai-leung, Sir Sze-yuen Chung Professor in Precision Engineering, Chair Professor of Precision Engineering and Associate Head of the Department of Industrial and Systems Engineering, and Director of the Research Centre for Deep Space Explorations of PolyU, said the team is deeply grateful for the opportunity granted by the motherland. “Because the Moon’s rotational period is tidally locked in sync with its orbital period around the Earth, the moon’s far side remains invisible to Earth’s observation, making direct communication with the vehicle impossible. As a result, the difficulties and challenges of sampling on the lunar far side are greater than those encountered on the near side. Drawing on our experience from previous projects, we’ve successfully integrated numerous enhancements into the system, enabling a timely sampling within a more restricted timeframe. We are very grateful to our Nation for entrusting us with the task, showcasing Hong Kong’s space research capabilities and playing a pivotal role in the journey of our Nation’s space missions,” Prof. Yung explained. Unlike previous methods adopted by other countries involving drilling or manual excavation, PolyU’s “Surface Sampling and Packing System” is designed as fully automated multi-point lunar surface sampling and with a packaging mechanism. In Hong Kong, PolyU was involved in the design and manufacturing of Samplers A and B, together with two accompanying high temperature Near-field Cameras for multiple-point surface sample collections, and automatic vision guidance of the sampling, sample deposition and sample container pickup and precision placement into the ascender. The PolyU-designed and manufactured flight units also included a primary sealing and packaging system that consisted of a sample container and its sealing mechanism. The sampling process briefly started with the Near-field Cameras mounted on the robotic arm next to Samplers A and B. These Cameras guided the sampling and sample deposition into the PolyU sample container in the primary sealing and packaging system. Upon the completion of the sampling process, the sample container was sealed by the sealing and packaging device for picking up by the sampler which was vision-guided by the Near-field Cameras for automatic precision insertion into the ascender for transporting back to Earth. Since 2010, PolyU has been participating in the Nation’s space exploration programmes and collaborating with the China Academy of Space Technology to develop and manufacture sophisticated space instruments. PolyU researchers have also used advanced topographic mapping technologies to evaluate and identify the best landing sites for spacecraft. These contributions supported the success of the Nation’s lunar exploration missions, including Chang’e-3, Chang’e-4 and Chang’e-5, as well as the Mars exploration mission Tianwen-1.
