Towards a Wireless and Low-Power Infrastructure for Representing Information Based on E-Paper Displays

Abstract

There has been much interest in replacing traditional information supports with more technological solutions in recent years. New technologies which allow paper-like perception with minimal power needs have emerged as low-power wireless scenarios. A priority for these new supports is to create the architecture for a scalable solution which maintains minimal power requirements. The retail industry demands a new information infrastructure that improves customer and employee satisfaction. In this work, authors propose an information provision architecture based on E-Paper and carry out an experiment where different smart labeling architectures based on Paper, E-Paper, LED liquid crystal display (LCD) and Dot-matrix LCD were tested in order to determine which is best suited for a real labeling environment. Enclosed in a research project called SMARKET, the authors pilot-tested the work in a real supermarket, having the opportunity to survey employees and customers about satisfaction and frustration with the use of the architectures proposed in this research work.

Protecting Private Communications in Cyber-Physical Systems through Physical Unclonable Functions

“…This configuration is vulnerable to physical attacks (i.e., people physically manipulating the device), as the key could be read from the memory by unauthorized people. This risk, moreover, is especially relevant in CPS, as many deployments are isolated, unmanaged, and unattended [10]. New mechanisms to create or protect keys against any cyber or physical attacker are, then, required.…”

Improving Learning Tasks for Mentally Handicapped People Using AmI Environments Based on Cyber-Physical Systems

“…is proposal aims to turn into the basic document for the future commercial CPS. For example, following this line, some research works have investigated the use of low-energy devices in order to display information in different scenarios such as supermarkets, production systems, or hospitals [9,10]. e basic idea is to employ new, open, and more efficient technologies such as the electronic ink in order to improve the current automatic industrial systems based on proprietary technologies [11,12], programmable logic controller (PLC) [13,14], and very lowlevel protocols such as OPC (Object Linking and Embedding for Process Control) [15].…”
