In this paper, we propose a new ubiquitous computing environment composed by visual markers and event-driven compact devices. We employ the VCC (Visual Computer Communication) method, which we have al- ready proposed as the information displaying method on visual markers. In the VCC method, a marker is composed of multiple tiles and their color changes at a certain interval of time, by which the marker can send dozens byte of information. In our research, in order to enhance the facility of VCC marker, we use rule-based compact devices to process various types of data and to change information shown in a VCC marker dynamically. The combination of VCC markers and compact devices enable various services such as presentation of real world information collected by compact devices and control of appliances via compact devices.
