Connected Worker Solutions

The complexity of fieldwork, the decline in the working population due to aging, the mass retirement of skilled workers, and the necessity for remote support due to COVID-19 are urgent issues across all industries. Our connected worker solutions for on-site DX simultaneously “maintain and improve on-site utilization rates” and “eliminate lost sales opportunities.”

Our solutions support digitization across the entire workflow by connecting on-site workers to the Internet at any time without stress. That enables real-time remote support for on-site work, digitalizing experienced workers’ skills to pass on, and improving efficiency by reducing non-core office workers.

On-site workers merely need to install THINKLET®️ without learning new operations. They can use PCs or smartphones to to activate on-site video distribution from the support base remotely.
The software swiftly connects the site with headquarters to provide audio and video support for the site.

THINKLET®️ Features

  • A lightweight, ergonomic, neck-mounted design for operator’s ease of use, leaving their hands free for work
  • The device is equipped with 5 microphones, making it possible to record both the wearer’s voice and the voices of people the wearer is speaking to.
  • “Mimi® XFE” AI voice processing enables clear voice recording even in noisy environments
  • The device’s 8-megapixel wide-angle camera allows recording clear and detailed images during work
  • Equipped with Wi-Fi and 4G LTE, the device is always connected to the cloud. Data can be collected and verified in real time.
  • The USB Type-C socket enables the device to be linked with external devices such as smart glasses and wearable sensors.
  • The device is waterproof to IP54 standards and dustproof; hence, it can be used in the rain.


We established a study group about on-site DX/connected workers with multiple partner companies in building development/construction/real estate. Through the study group, we discussed labor shortages, the impact on sites due to recent changes in the external environment, such as COVID-19, and industry issues faced by each company and other industries. After sharing information on how different industries digitalize the site, we discussed our target site issues, hypotheses to confirm, and the best way to realize these hypotheses technically.

We also demonstrated how to create an educational manual for process division and an application for multilingual speech translation. After discussing the confusion that emerged in various fields due to COVID-19, we introduced the topic of DX conversion using connected workers by demonstrating wearability, and the practicality of the delivered audio and video, with an actual THINKLET®️ device.

We received feedback from the participating companies about use cases and discussed various hypotheses for remote virtual viewing in the construction and real estate industries that involved advanced rush response, remote support for site supervisors, and inspection evidence and form creation support regarding the use cases from other industries.

Moreover, ideas were discussed for the construction and real estate industries about new use cases for the remote product inspection of steel frames, the construction of cutting-edge equipment, and the expansion of potential job applicants in the industry through on-site video distribution during advanced work.

We also shared the importance of proof of concepts (PoC) for future development by introducing PoC flow using connected workers. That is, if multiple inspections are performed at once, the content of any improvements cannot be properly clarified, and the resulting PoC will be of poor quality.


The study group provided valuable output on the optimal ways to utilize connected workers in the construction and real estate industries through the active exchange of opinions with participating companies, with several points to keep in mind. In remote virtual viewing, appealing aspects of real estate can be demonstrated in a realistic manner, including the exterior and surrounding environment. However, some elements can only be directly experienced when on-site, such as odors and minute sounds. This confirms the importance of creating an environment wherein real estate contacts can be created remotely with peace of mind by providing proper communication and ensuring guarantees are in place from the site.

We confirmed the importance of actively utilizing skilled workers after retirement to avoid overwhelming the retired workers. We also confirmed the importance of quickly determining whether rushing is necessary when designing a flow that allows for the smooth matching of skilled workers. A sophisticated rush response through remote support enables early recovery by rushing in the event of equipment failure/trouble. Moreover, a record of response evidence leads to faster response times and reduction of the response costs incurred by the company.

It was also pointed out that, similar to rush responses, remote support of on-site supervisors emphasizes the need to utilize skilled workers after retirement and the establishment of a system for assignment and pre-handling. In addition, the skills required for on-site and remote guidance vary. The need to develop rules for the provision of remote support that consider human relationships in the construction industry was also raised.

This confirmed the advantages of THINKLET®, which enables interactive complementation by voice recognition, in that it allows inspection evidence and form creation support to be concentrated on core work by automating work records and report creation using on-site audio and video data. However, even in this form, the granularity of information will vary due to differences in skill level.

Future Developments

We are working on a white paper for the construction and real estate industries about THINKLET® packages. Moreover, we are looking for partners who are interested in participating in PoC to help define requirements for product development, solve problems at different sites, verify the effectiveness of the product, and implement de facto standards for the industry as a whole.

Japan has many “workplace skills” considered to be soft power assets. However, they are not being exported overseas due to the barriers presented by Japanese personalities, language, and culture. At the same time, these “workplace skills” are also increasingly rare assets that are being lost due to the declining birthrate, aging population, and the mass retirement of skilled workers. Our goal is to use technologies such as voice recognition, multilingual translation, and remote control to digitize “workplace skills” before they are lost. This is to enable succession by the next generation and overseas expansion through connected worker solutions.

This will enable the globalization of Japanese quality and the maintenance of the country’s international competitiveness through the use of Japanese-made AI. Fairy Devices aims to create a future in which its products thrive as people’s partner fairies to support them. THINKLET® offers “a world in which people and machines live in harmony” with “skilled craftsman AI” from Japan that uses Japan’s unique knowledge and technology strategies to capture the global market, which would be difficult for GAFAM or BATH to achieve.
