“…An approach with wireless pixels is an ambitious goal but would be very powerful in terms of enabling savings on structure and installation costs and facilitating a wide range of artistic expression. Although supplying wireless power is still a major challenge [Roundy et al 2004;Paradiso and Starner 2005], the use of 2D sheets [Lifton et al 2005;Nakatsuma et al 2008;Makino et al 2005] can offer a possible starting point for addressing this problem.…”

Large-scale displays for public spaces---constellation of departure

The use of large visual displays in public spaces such as large buildings has become increasingly popular. Public art can make use of the characteristics and context of the site. However, it is difficult to install new displays in existing buildings because of the large, rigid hardware associated with such displays. In this article, we describe a robust, lightweight, low-profile, and fully restorable display system that can be easily and quickly installed for use in existing public buildings. We considerably reduced the number of physical components and the system weight with our proposed method, which can be optimized for any planned content. We describe the technical design and implementation of the display system and discuss some of its applications for public audiences. We then report a three-month field trial that we conducted at an airport terminal building. We discuss the advantages and effectiveness of this system in light of the field trial results.

“…Then, we discuss some seminal works on real-time communication in multi-hop networks and traffic shaping to provide communication bounds for real-time applications. A multi-modal sensor network was proposed in [14], as a scalable sensor network with up to hundreds of nodes per square meter. However, due to the wireless nature of the links (infrared), contentions and collisions substantially increase the cost of communication.…”

XDense is a novel wired 2D-mesh grid sensor network system for application scenarios that benefit from denselydeployed sensing (e.g. thousands of sensors per square meter). Itwas conceived for closed-loop cyberphysical systems (CPS) thatrequire real-time actuation, like active flow control (AFC) onaircraft wing surfaces. XDense communication and distributedprocessing capabilities are designed such that they enable toextract complex features within bounded time and in a responsivemanner. In this paper we tackle the issue of deterministic behaviorof XDense. We present a methodology that uses traffic shapingheuristics to guarantee bounded communication delays and thefulfillment of memory requirements. We evaluate the model forvaried network configurations and workload, and demonstratethe effectiveness of running real-time applications supported onXDense.

Abstract-This paper shows the possibility of two-dimensional communication between electronic devices by using only one conductive surface. An analysis of the expected magnitude of the signal at the reception point as a function of distance and electrical parameters of the conductive surface is presented. Measurements on surfaces from 0.4 to 2.56 m 2 and with sheet resistances from 77 to 1462 ohm/square prove the correctness of this analysis. In addition, practical rules to locate and orient the transceivers are given. Prototype transceivers connected to a plane with one conductive surface able to communicate at 100Kbit/s at a distance of 2m are described.
