Abstract

In the recent years, several papers have implemented methods which seamlessly integrate data streams into high frame rate monitors without affecting casual viewer experience. This paper proposes an improvement to existing systems which can in theory increase the data throughput of the data stream several times. Exploiting the same characteristics of human vision as related papers, grid containing different colours is encoded into a video. Testing was conducted to determine the possible uses of this approach. It was determined that 2x or even higher increase is possible however there seems to always be a visual artifact present. The testing also revealed a need for further testing to determine the best possible configuration (amount of colours) to use as well. This testing would also increase the reliability of the data gathered as the experiment was limited by time.
