Prologic Robotics is a local brand based in Hong Kong, established in 2010. The Prologic Robotics brand team focuses on developing cutting-edge intelligent automatic robots and launched the intelligent automatic vacuuming robot in the same year, committed to simplifying people’s lives through technology. In order to expand its influence in the market, we have conducted market analysis of Prologic using IBM data analysis technology. Firstly, we collected and organized a large amount of market data, including market share, consumer demand, and competitors’ information, based on its target market (Hong Kong). Secondly, we conducted descriptive statistical analysis to help Prologic understand the basic features of the data, such as mean, median, standard deviation, and the distribution of the data, in order to better understand market trends and consumer demand. Then, we used time series analysis, regression analysis, and machine learning algorithms to conduct predictive analysis, which helps the Prologic brand predict future market trends. Finally, we conducted market data mining for Prologic, helping the company discover patterns and relationships hidden in the data. In the future, in order to expand Prologic’s market competitiveness, we will continue to collect and organize market data from foreign markets (such as Seoul, Tokyo, Taipei, and Singapore) that Prologic benchmarks against, and continue to track and analyze Prologic’s market performance using IBM data analysis technology, providing more specific and accurate market analysis reports for the company. We believe that through these market analysis efforts, Prologic will be able to better meet consumer demand, improve market competitive-ness, and achieve sustainable development.

Based on the literature review, researchers reported that at most, 24.6% of young children in the world were estimated to have speech delay or speech sound disorder (SSD). Once children with SSD are identified, speech-language pathologists (SLPs) select initial therapy programs for children with regular review and adjustments on therapy. The success of therapy highly re-lies on the effectiveness of long-term home training. In this project, we carry out human voice analysis and design and implement a virtual teacher for home training in speech therapy. For the first part of this project, we conduct a sound analysis research to see if children’s Cantonese pronunciation is correct. Once the children’s voices are captured, human voices can be automatically transferred for waveform analysis, allowing a large number of tasks to be completed quickly. The created waveform is compared to the standard waveform. If the majority of the waveform is inconsistent, it suggests that the pronunciation of children is not standard. As a result, it points out children’s pronunciation problems and generates feedback quickly. Through the waveform diagram, our system can accurately process and analyze the sound, as well as eliminate the inaccuracy caused by varied timbres of children, making the analysis more accurate and effective. For the second part of this project, we implement a virtual teacher to carry out training for speech therapy. It can achieve low-cost popularization, timely correction of children’s pronunciation problems.

Nowadays, mobile games are commonly used for children training and therapy. Literature show that multisensory activities help raise the children’s interest in their learning, raise their concentration and reinforce their memories. Portable multi-sensory games can provide an immersive training environment for children anywhere. In this paper, we design and develop a portable multisensory educational game, Fun2Write, to help children to learn and recognize Traditional Chinese words. It could also help to evaluate how effective it is on encouraging children to learn and effectiveness of game-based inter-active teaching method. The game mechanism is based on whack-a-mole game, each mole holds a card with a Chinese character, players have to whack the correct mole in order to gain points, which is the metric to assess how well does the player recognize Chinese characters. Unlike conventional control such as mouse, keyboard or screen tapping, Fun2Write utilize con-troller that has in-built gyro system (Such as Nintentdo’s Joycon) to simulate real life mole-whacking experience. The controller’s mechanism is similar to laser-pointer, which allows pointer movement in 3D space, and accurately tracks the movement of the players hand and adjust the pointer’s position accordingly. When the pointer hovers above the mole. Upon locking onto the target, the player can then perform swinging gesture to simulate swinging a hammer, this design is intuitive and help reducing cognitive load on re-learning controls. The game can be accessed on most of the hardware such as smart phone and computer. To extend the portability, we design and develop a low-cost portable cave by using projectors. The output results demonstrate the effectiveness of a portable immersive environment application.

The Government plans to renew the Kowloon City district (The KC-017 scheme). In order to preserve the history of the Old Kowloon City and promote Sustainable development goals for sustainable cities and communities, “VR Metaverse in Kowloon City” is created. The 3D model of the four key historical buildings namely Lok Sin Tong Primary school, Kowloon Walled City Park, Wong Chun Chun Thai Restaurant and Kowloon City Hospital were built and virtually presented. Mini-games and interactive education activities are incorporated in the project to make it more interesting and to allow player to get familiar with the unique characteristics of Kowloon City. For example, in the chat room, users may share their experiences inside the Kowloon City as if they were meeting face-to-face. Users may “walk” inside the Lok Sin Tong Primary School to visit the school using the first-person view. They may also “walk” the Kowloon Walled City Park, and collect the play cards which show the lifestyle of the locals in 90s. In the famous Thai Restaurant, user may even “order” the dishes and experience the Thais living in Kowloon City. It is hoped that this project can help promote the importance of history conservation among the public.

MedMate is a user-friendly medication management solution designed for seniors. It ensures medical compliance by providing timely reminders and clear instructions. The system includes an Electronic Health Record (EHR) platform that connects patients, doctors, and pharmacists, facilitating data sharing and adherence tracking. The dispenser, refilled by pharmacists, has clearly labeled compartments for safe storage and accurate medication. It dispenses pills automatically at the correct time, with reminders provided through a red light, verbal announcements, and SMS for compatibility with older mobile devices. MedMate includes sensors to ensure pill count accuracy and to check if medication has been taken. Unused pills are automatically disposed of after 30 minutes to prevent confusion. The system is set up by placing labeled drug bottles into corresponding racks. As doctors update medication details in the EHR system, pharmacists refill the bottles accordingly. The app generates reports of patients’ medication patterns, shared with doctors through the EHR system. Ideal for seniors dealing with polypharmacy, MedMate can be set up remotely by pharmacists, and the dispenser’s racks are detachable for easy refill. The service operates on a monthly subscription model, providing flexibility for users..
