Asukanet Co., Ltd. (Hiroshima, Hiroshima; President: MATSUO Yuji), MIRAIBAR Inc. (Yatsushiro, Kumamoto; Chief Executive Officer: TAMAMIZU Haruki) and Mitsui Chemicals, Inc. (Tokyo: 4183; President & CEO: HASHIMOTO Osamu) today announced that their jointly developed touchless aerial display solution has been adopted for use at Sakai Town Office (Mayor: HASHIMOTO Masahiro) in Ibaraki Prefecture. Ticket machines using the technology were installed at a service desk for local citizens on May 18.

Intended for use by local citizens wishing to complete such procedures as notifying the town of a change of residence or applying to register their official seal, the ticket machines feature a display that appears to float in midair. Without actually touching the screen, the user can “press” the midair button for the department handling the relevant procedure, upon which the machine prints out a number indicating the user’s place in the queue for that department. Sakai’s decision to adopt the technology was motivated by the recognition that touchless displays could help prevent the spread of COVID-19. The project partners intend to work with Sakai as it considers the introduction of these displays at other municipal facilities in the town.

The three companies aim to continue collaborating in efforts to resolve the challenges faced by customers in a variety of sectors, including local government, hotels, food distribution and real estate.
