城市环境越来越多地充斥着数字显示系统，这些系统不灵活、扁平、有限、高分辨率和反应迟钝。在本文中，我们探索了物理实例化像素的潜力，使灵活，可重构，无界，低分辨率和响应的城市显示成为可能。城市像素是城市空间物理像素无线网络中的节点。每个像素单元包括一个微控制器、射频收发器（433 MHz）、LED模块（10个明亮的白光LED）、可充电锂离子电池组、红外传感器和可再生能源，如光伏电池。两个亚克力半球体（直径4英寸）保护组件免受元素。通信不需要额外的布线，单元可以单独安装到任何表面。2008年6月1日至6月7日，一个由50个城市像素组成的小规模原型网络在苏格兰因弗内斯的伊甸园庭院剧院的一个舞台上展出。市民可透过短信更改展览图案，或透过手电筒与个别单位互动。几个晚上，我们观察并非正式地采访了剧院的客人和与舞台互动的路人。基于这些结果，我们概述了一个令人兴奋的问题空间，用于设计城市的显示和照明系统。
Urban environments are increasingly filled with digital display systems that are inflexible, flat, bounded, high-resolution, and unresponsive. In this paper, we explore the potential of physically instantiated pixels that enable flexible, reconfigurable, unbounded, low-resolution, and responsive urban displays. Urban Pixels are nodes in a wireless network of physical pixels for urban spaces. Each pixel unit includes a microcontroller, RF transceiver (433 MHz), LED module (ten bright, white LEDs), rechargeable Li-Ion battery pack, IR sensor and renewable energy source such as photo-voltaic cells. Two acrylic half-spheres (4-inch diameter) protect the components from the elements. No additional wiring is needed for communication and the units can be mounted individually to any surface. A small-scale prototype network of fifty Urban Pixels was displayed on a façade of Eden Court Theater in Inverness, Scotland from June 1 - June 7, 2008. The public was encouraged to change display patterns via SMS or to interact with individual units via flashlights. We observed and informally interviewed theater guests and passers-by interacting with the façade for several nights. Based on these results, we outline an exciting problem space for designing displays and lighting systems in cities.
