摘要

提出了一种标签系统,为普适计算提供了一种实用的方法。它提供了易于分发的小而低功耗的标签;不需要特殊的设备来读取标签(未来),从而使其随时随地使用;并且在角度和距离上具有广泛的读取范围,扩展了基于标签的应用的设计空间。该标签由一种液晶(LC)和一个反向反射器组成,通过切换液晶来发送自己的ID。使用发射红外线的深度感测相机作为标签读取器;我们假设它将成为用户日常设备的一部分,比如智能手机。实验证实了其潜力,并对普通红外相机进行了测试以进行比较。结果表明,该标签系统在距离(高达8m)和视角偏移方面具有较宽的可读范围。还开发了几个应用程序来探索设计空间。最后,讨论了当前设置的局限性和可能的改进。

Tag system with low-powered tag and depth sensing camera
A tag system is proposed that offers a practical approach to ubiquitous computing. It provides small and low-power tags that are easy to distribute; does not need a special device to read the tags (in the future), thus enabling their use anytime, anywhere; and has a wide reading range in angle and distance that extends the design space of tag-based applications. The tag consists of a kind of liquid crystal (LC) and a retroreflector, and it sends its ID by switching the LC. A depth sensing camera that emits infrared (IR) is used as the tag reader; we assume that it will be part of the user's everyday devices, such as a smartphone. Experiments were conducted to confirm its potential, and a regular IR camera was also tested for comparison. The results show that the tag system has a wide readable range in terms of both distance (up to 8m) and viewing angle offset. Several applications were also developed to explore the design space. Finally, limitations of the current setup and possible improvements are discussed.
