【2020 Solutions】 Always Measure Temperature, Prevent Wandering, AI Helps with Wuhan Virus Isolation

As the novel coronavirus epidemic continues to spread, the number of quarantined and isolated individuals steadily increases, becoming an 'unbearable weight' for managers. SITU Technology, along with Myte Electronics, Ai Micro Science, and String Cloud Technology, have collectively developed a 'Home Isolation Personal Location Tracking System' for COVID-19, addressing the issues of isolated individuals wandering and holes in epidemic tracking.

On the afternoon of February 12, 2020, as the novel coronavirus epidemic continued unabated, home-isolated individuals were seen wandering around, causing widespread alarm, with anxious faces hidden beneath white masks. A 'Public Cloud Location and Monitoring Seminar' held in Taipei unexpectedly helped forge a significant epidemic prevention coalition.

Formed by a coalition of established and startup companies including SITU Technology, Myte Electronics, Ai Micro Science, and String Cloud Technology, they introduced the COVID-19 'Home Isolation Personal Location Tracking System'. In the abodes of those quarantined, whether in centralized isolation spots or home setups with temperature monitoring platforms, an automated reporting process alerts immediately if abnormalities are detected, significantly reducing the burden on epidemic staff and preventing quarantined individuals from easily leaving their premises, thus plugging the gaps in epidemic tracking.

Home Isolation Wandering, Epidemic Phones Not Enough

As the number of confirmed cases of the coronavirus rises, in order to effectively prevent community transmission, the Central Epidemic Command Center has specified that all entrants must undergo individual home isolation, home quarantine, and self-health management; those in home isolation and quarantine must rest at home for 14 days and must not go out, during which community leaders and police officers should ensure at least two temperature checks daily.

However, as the epidemic intensifies and the number of people requiring a 14-day home quarantine skyrockets, there is a dire shortage of equipment and personnel. This includes 2,000 location monitoring phones provided by the government being insufficient; additionally, the limited number of epidemic personnel face increasing work pressure, urgently necessitating the use of technological tools to aid the situation.

Shih-Juan Lin, founder and CEO of SITU Technology, explains that the COVID-19 'Home Isolation Personal Location Tracking System' is divided into hardware and software components. The hardware includes a temperature patch from Ai Micro Science and an unlimited location tracking device (USB receiver) provided by String Cloud Technology. The patch, which must be placed in the armpit of the quarantined individual, is capable of measuring temperature 24 hours a day; the receiver uploads temperature and location data to the SITU Technology's cloud positioning engine. This data is analyzed to track temperature trends and accurately predicts the likelihood of diagnosis.

Temperature Measurement + Indoor Positioning System Reduces the Likelihood of Community Infections

SITU Technology was officially established in 2015, with co-founders from various fields including indoor positioning, robotic platforms, imaging graphics, machine learning, and cloud computing. Shih-Juan Lin states that the unified epidemic phone GPS systems, whether used for centralized quarantine, centralized isolation, home quarantine, or home isolation, have two drawbacks: the resolution is too high; and they cannot track vertical movements, meaning that they cannot detect movements from one floor to another, or from one room to another, which greatly increases the potential for community transmission.

Compared to traditional methods, SITU Technology's positioning sensing system uses various devices, including optical lenses, LIDAR, and ultrasound, to sense wireless signals at each point like an indoor Google car, accumulating extensive and comprehensive data to build an accurate floor plan. Simply said, by crossing-comparing wireless signals received by multiple indoor receivers and using AI deep learning, the positioning can break through spatial restrictions and achieve greater accuracy.

In addition to precise positioning, by analyzing the mobility tracks of isolated individuals and groups and tracking their contact history, it is further possible to grasp the virus transmission routes, offer early warnings, and avoid community infections.

On the management side, computers and large electronic displays can observe the temperature, battery usage, and signal strength of the group patches (isolated individuals). Once it is detected that an isolator has left their designated location, an automatic alarm signal is immediately triggered, allowing management personnel to take immediate action. On the other hand, isolators can also record their own temperature changes on their phones, and in the event of an abnormal situation, they can immediately notify the quarantine unit for further checks.

This system was conceived and formed on February 12, and within just over a month, has been empirically tested in centralized isolation facilities in Taipei City and New Taipei City of around 50-bed scale, with effective implementation. In the future, there is the potential to expand to factories, offices, and other larger scale, high-risk areas for temperature management. After the epidemic, this system can also be expanded for use in emergency rooms, maternity wards, postpartum centers, and long-term care institutions.

Complete checkout in 1 second, Viscovery AI image recognition assists smart retail

Artificial intelligence AI has gradually changed the way various industries operate in recent years However, most of the work is still done by humans, with AI playing a supporting role This has led to emergence of the term "AI Copilot," which stands for "AI-driven tools or assistants" that aim to assist users in completing various tasks and improve productivity and efficiency The concept of AI Copilot comes from the role of "co-pilot" During flight, the co-pilot assists the main pilot in completing various tasks to ensure flight safety and efficiency In fact, there have been signs of various "machines" beginning to play the role of "copilot" in different fields since the Industrial Revolution, assisting humans in completing heavy physical and repetitive tasks, greatly improving factory production efficiency, and driving rapid economic development Following the advancement of computing equipment and breakthroughs in machine learning, deep learning, and image recognition technologies, the concept of AI Copilot has gradually taken shape The development of AI Copilot marks the transition from "machine-assisted to AI-assisted" Early robots could only complete preset repetitive tasks, but today's AI copilot can learn and adapt to new environments and tasks, and continuously optimize its performance in practical applications This transformation not only changes human-machine interactions, but also has a profound impact on various industries The application scope of AI copilot covers various industries, including finance, healthcare, manufacturing, education, retail, etc, and are everywhere to be seen Application of AI copilot in the retail industry AI image recognition checkout In the retail industry, the application of AI copilot has begun to show concrete results Take Viscovery's AI image recognition checkout system as an example This system is a type of AI copilot model that helps store clerks speed up checkout or assists consumers in simplifying the self-service checkout process The store clerk needs to scan the product barcodes one by one in the regular checkout method If a product does not have a barcode, such as bread and meals, the clerk needs to first visually confirm the items, and then input them into the POS checkout system one by one Based on actual measurements at a chain bakery, it takes 22 seconds for an experienced clerk from "visual recognition" to "entering product information of a plate of 6 items into the checkout system" New clerks may need even more time In addition, according to a Japanese bakery operator, it takes 1 to 2 months to train employees to become familiar with products Now with AI image recognition technology, store clerks let AI handle the "product recognition" step, and AI will play the role of copilot, quickly identifying items within 1 second, speeding up checkout to save 50 of checkout time, and optimizing customers'shopping experience The time cost of training employees to identify bread can also be effectively shortened Even for products with barcodes, AI can quickly identify multiple items in one second, which is more efficient than scanning barcodes one by one The self-checkout system "assisted" by AI image recognition allows consumers to successfully complete shopping without the help of store clerks, eliminating the trouble of swiping barcodes or searching for items on the screen, which improves the shopping experience In a time when store clerks are hard to hire due to labor shortage, this also helps stores reduce operating costs AI quickly identifies multiple checkout items in just one second Source of image Viscovery Recently, startups dedicated to developing AI image recognition checkout solutions have emerged in various countries The most lightweight solution currently known is in Taiwan It can be immediately used by installing a Viscovery lens and a tablet installed with Viscovery AI image recognition software at the checkout counter to connect to the store's existing POS checkout system There are various integration methods, including plug-and-play and API solutions integrated with the store's POS system Viscovery AI image recognition system can be painlessly integrated with the store's existing POS system Source of image Viscovery Example of AI image recognition checkout Currently, the Viscovery AI image recognition system is being used in bakery chains in Taiwan, Chinese noodle shops in Singapore, micromarkets in department stores in Sendai, Japan, and Japanese bakeries and cake shops Over 7 million transactions were completed through this AI system, which identified more than 40 million items These use cases demonstrate the extensive application of the Viscovery AI image recognition system in the retail industry In the future, the company will continue to explore the various possibilities of using Vision AI in retail and catering nbsp The Viscovery AI image recognition system is already being used in bakeries, cake shops, restaurants, and convenience stores in Japan, Singapore, and Taiwan Source of image Viscovery
