Commanding the Cloud by Moving a Camera Phone

Abstract

Major innovations are based on novel input devices, for example, the mouse and its role in revolutionizing the PC world. Some innovations are even over-looked, such as the touch screen, until it made quite a trendy return in the shape of the Apple iPhone. All such specialized devices will dwarf into remote handling applications in the cloud by a generalized device, that is, the camera phone. This paper shows that camera movement can be extracted from capture images by a limited block-matching based search. The CPU load is less than 20% and does not increase with image size.
