BB BB BB • Proposal of a method for distributing content between electronic paper signage using human movement as a communication medium • Verify the basic operation of the proposed method by implementing a prototype BB A Proposal of an Information Delivery Method using Human Movement as a Communication Medium for Electronic Paper Signage Hokkaido Information University Takafumi Akiba and Tsubasa Yumura Proposed Method Prototype implementation Abstract Electronic Paper Signage (EPS) • A type of digital signage that uses electronic paper technology • Electronic paper consumes power only when the screen is updated Information display in mountainous areas without power or communication infrastructure • Displaying information and warnings on paper • Local governments and conservation groups patrol for replacement: high renewal costs Introduction E-paper E-link Solar Powered 13.3inch Display | AVLink Digital Signage https://www.lcdhome.live/product/e-paper-e-link- solar-powered-13-3inch-display/ • EPS is expected to replace paper media. • Frequent information updates require updates via Internet communication • In mountainous areas where communication infrastructure cannot be established, it is difficult to update information from remote locations Realization of an EPS update method that is energy efficient (normally off) and independent of communication infrastructure. Transporting updated EPS content via devices owned by individuals • Mobile devices such as smartphones store and deliver content • Transferring content when a mobile device approaches an EPS BB Future work Detects human proximity and activates microcomputer (proximity drive function) • EPS remains in sleep mode at all times and activates when someone approaches • Aiming for a normally off design Use case examples •Use at amusement facilities and outdoor festivals Receive Send Hardware • Using M5Paper v1.1 • Touchscreen-compatible E-Ink device • Equipped with ESP32 (BLE communication possible) Communication standards • Bluetooth Low Energy (BLE) オン Mobile Terminal Piezoelectric Element Mat EPS Microcomputer Mändjala Study Trail | Visit Estonia https://visitestonia.com/en/mandjala-study-trail Content exchange •Mobile devices and EPS perform short-range wireless communication •EPS performs content version comparison processing A) Data is the same: No updates B) EPS data is outdated: Update EPS content C) ESP data is new: Mobile device content update
