On the occasion of Tactile Paving Day,*2 ACCESS Co., Ltd. (President & CEO: Kiyoyasu Oishi; head office: Chiyoda-ku, Tokyo, Japan; hereinafter “ACCESS”), Seiko Holdings Corporation (Chairman & Group CEO, CCO: Shinji Hattori; head office: Chuo-ku, Tokyo, Japan; hereinafter “Seiko”), Sakai Silk Screen Co., Ltd. (President: Shoji Taniguchi; head office: Yoshida-gun, Fukui Prefecture, Japan; hereinafter “Sakai Silk Screen”), and PLAYWORKS Inc. (President: Keita Takizawa; head office: Fujimi, Saitama Prefecture, Japan; hereinafter “PLAYWORKS”) are pleased to announce the joint development of the world’s first*1 “thin tactile paving block with built-in solar beacon” and commencement of provision and field testing of a prototype for railways, airports, and public facilities, etc. by ACCESS.

The “thin tactile paving block with built-in solar beacon” is the world’s first product to feature a solar-powered Bluetooth® Low Energy (BLE) beacon installed in a thin tactile paving block for installation on walking surfaces to safely guide the visually impaired. By installing this tactile paving in and around places such as train stations and airports, it is possible to provide directions and facility guidance to the visually impaired via the transmission of BLE radio signals to their smartphones. If the user is wearing earphones connected to their smartphone, they can receive audio guidance and other information without having to take their smartphone out of their bag or pocket.

BLE radio signals transmitted by the “thin tactile paving block with built-in solar beacon” are picked up by smartphone.
Hands-free reception of audio guidance via smartphone

This tactile paving block is a sheet-type paving block made using weatherproof polyurethane that is very thin, having a thickness of just 7 mm (protrusion height: 5 mm; sheet thickness: 2 mm) even while having a solar-powered beacon installed. With an adhesive aluminum sheet on the back, it can be easily affixed to any flooring material. It can also be used to easily replace existing tactile paving. Because of its use of highly efficient photovoltaic (“solar”) power and power-saving control technology, it can operate sufficiently under light with a brightness of indoor lighting and does not require maintenance such as battery replacement. Moreover, because any type of characters/symbols can be printed onto the tactile paving, it can also be used to provide visual guidance for the non-visually impaired. This truly is the ideal product for urban development in the age of SDGs with the aim of achieving a sustainable, diverse, and inclusive society.

The structure of the tactile paving block incorporates a small, low-power-consumption BLE transmission module and solar panel developed by Seiko Holdings Group into Sakai Silk Screen’s thin special sheet. (Patent application has been made.) In addition, the development of a smartphone app that provides guidance and other information for the visually impaired has been achieved by combining ACCESS’ software development capabilities with PLAYWORKS’ comprehension of the issues and needs of the visually impaired, as well as their service design capabilities. Business and sales promotion and implementation support related to the beacon will be overseen by ACCESS.

Together, ACCESS, Seiko, Sakai Silk Screen, and PLAYWORKS are supporting the development and provision of services to help businesses that build social infrastructure, such as railways and airports, to achieve the United Nations’ SDGs.
