In the past, managing and using a space required a huge workforce. However, different users mean different function needs. This leads to more input in management. The National Library of Public Information has designed and built “So Young Hall” for young people. By importing IoT, RFID, webcams, and web-based interfaces, librarians can remotely manage and adjust the environment in real-time, including lights, curtains, speaker volume, and windows transparency, etc. So Young Hall is not just a static space for lectures or workshop, it can also be used for dynamic activities, such as dancing practice for young people or board game play for parents and children. About The board game service, it is combined with QR codes for readers’ self-service. Readers can use the space by scanning the QR code on the board game box to activate the hall. In addition, young people can also use this hall for learning, discussion, or practicing dancing through online reservations. The library also provides an app for readers to use as a self-service to control devices in the hall, according to their specific usage needs. When managing the hall, librarians can also use a tablet or PC to automatically schedule different environmental conditions according to the needs and time of daily activities. Adapting IoT makes the usage of this hall more economical and efficient and improves usage flexibility and management efficiency. It reduces the management burden and makes services more in line with user needs.
