Abstract

With technologies available now, there are only a few virtual objects that augmented reality content can create. So, wider application of it is limited. If people want to realize any augmented reality content, out of a vast amount of materials available as well as virtual objects, the number of virtual objects that markers can render should be made to go up along with the content. In a precedent study, IR LEDs markers render marker information following On-Off signals. The number of LEDs should be raised to render as much information as possible, subsequently leading to the problem of oversized markers. This problem can be solved by generating data signals through the blinking of LEDs. This research puts forward OOK Code algorithm that represents the mode of data transmission using the light of LEDs. The amount of information that can be rendered by a marker increases and the size of the marker gets smaller, which is a merit, when it receives data signals from light.
