A Research of Optical Tag System : Attaching Audio Data to Real World Object

在这项研究中，提出了一种新的光通信设备，它使用户能够选择他/她的指向动作的发射机。该系统的目的是为用户提供大量的数据，触发他/她指向真实的世界对象。实验结果表明，该系统具有足够的空间分辨率和时间分辨率，可以实现用户指示选择光发射机和利用脉宽调制光信号传输声音数据。所实现的系统连接到手机和用户的自然眼睛，并且这两个系统执行几乎相同的空间和时间分辨率。

In this research, a novel optical communication device, which enables a user to select a transmitter by his/her pointing action, is presented. The aim of this system is to provide a user to large amount of data, triggered with his/her pointing to real world object. Several experiment with implemented system prove this system has enough special resolution and temporal resolution to 1) select optical transmitter with user's pointing, 2) transmit sound data with pulse width modulated optical signal. Implemented system is attached to cell phone, and user's natural eye, and both systems performing almost same spatial and temporal resolution.
