We propose an efficient, augmented reality system for education utilizing scenarios acquired from the metadata of quick response (QR) code. Our system enables interaction using an assembled robot in a virtual environment. First, we build a virtual environment around the robot according to the metadata. In addition, we create and manage a wide variety of content using metadata. We estimate the camera pose by using both markerbased and markerless methods. Lastly, we use a Bluetooth module and metadata of QR codes to interact with objects in the virtual environment.

Overview

• Acquire the input stream using the camera
• QR code recognition from captured image
• Analyze the metadata and request content metadata
• Receive the content resource from a contents-data server

Metadata

• Two Types of metadata
  • QR code Metadata : basic contents information
  • Contents metadata : visualization for virtual environment
• Capacity of QR code is larger than other types of markers
• Content initialization in the virtual environment
• It easily manages various scenarios of contents
