The broader impact/commercial potential of this project is to dramatically transform the way people interact with and take information away from their physical environments. As information displays and mobile devices continue to multiply, they give access to ever increasing amounts of information. However, limited by their narrow input and output interfaces, personal devices inadvertently isolate their users from their immediate surroundings, instead focusing their attention toward the digital content in the cloud. Natural and effortless interaction could reconnect us to the physical world. Enabling seamless public-private communication has the potential to revolutionize physical display media, outdoor advertising, and public signage. It can generate new interactive experiences which are both immersive and personalized to the user bringing second screen applications beyond dedicated space, such as living room or airplane seat. Furthermore, it can shift digital content delivery from cellular networks to much more granular proximal networks. Going forward, in the advent of wearable camera-enabled devices, such technology can become the primary source of local context and intent information, relieving the user from the task of manual or vocal input. It will become the essential stepping stone as information services move from ?request? to a more powerful ?suggest? mode.This Small Business Innovation Research Phase I project will develop visual tags which can be scanned from afar while remaining visually unobtrusive. Visual barcodes trade small size, large decoding distance, and robustness. The proposed technology overcomes this trade-off by re-evaluating the characteristics of the usage scenario and fundamentally reorganizing the object-scanner relationship. This research will result in a practical system design which shifts considerable complexity from the scanner to the infrastructure. With lower complexity, the visual tags can be decoded quickly, robustly, and at distances beyond the reach of 2D barcodes. Additionally, by leveraging a novel spatio-temporal display technique, called VRCodes, the proposed visual tags are essentially imperceptible. This research will advance this technique to use no dedicated visual real estate. A side outcome of this work is a better understanding for how much information can be transmitted through the visible light channel unbeknownst to the end viewer.

该项目更广泛的影响/商业潜力是极大地改变人们与其物理环境交互的方式，并从他们的物理环境中获取信息。随着信息显示和移动设备的不断增加，它们提供了对不断增加的信息量的访问。然而，受输入和输出接口狭窄的限制，个人设备无意中将用户与周围环境隔离，转而将他们的注意力集中在云中的数字内容上。自然和毫不费力的互动可以将我们重新连接到物理世界。实现无缝的公私通信可能会给实体展示媒体、户外广告和公共标牌带来革命性的变化。它可以为用户带来身临其境和个性化的新互动体验，将第二屏幕应用程序带到专用空间之外，如客厅或飞机座椅。此外，它还可以将数字内容交付从蜂窝网络转移到更细粒度的近端网络。展望未来，随着可穿戴式摄像头设备的出现，这类技术可以成为本地上下文和意图信息的主要来源，将用户从手动或语音输入的任务中解放出来。它将成为信息服务从？请求？向？变得更强大？建议？模式。这个小型企业创新研究第一阶段项目将开发可从远处扫描的视觉标签，同时保持视觉上的不显眼。视觉条形码的代价是体积小、解码距离大和健壮性。建议的技术通过重新评估使用场景的特征并从根本上重新组织对象-扫描仪关系来克服这种权衡。这项研究将产生一个实用的系统设计，将相当大的复杂性从扫描仪转移到基础设施。以较低的复杂性，可以快速、稳健地解码视觉标签，并且可以在2D条形码无法到达的距离内解码。此外，通过利用一种称为VRCodes的新的时空显示技术，所提出的可视标签基本上是不可感知的。这项研究将推动这项技术的发展，不使用专用的视觉空间。这项工作的一个附带结果是更好地理解了有多少信息可以在终端观众不知道的情况下通过可见光通道传输。
