In this project, we use a camera-equipped mobile phone to view a PC screen (or public display) and we can control many interactions between the two devices. The essence of the idea is that, after estimating the planar projective mapping (homography) between the image on a mobile and a (possibly distant) display, any 'click' on the mobile's touch screen can be projected onto the correct corresponding point on the distant display. Of course, a wireless communication link is required so that the mobile can send its image to the display's PC, along with the point 'clicked' on its touch screen. Our idea has been reportred in a 'New Scientist' article in January 2008. This report made the top ten articles in the ACM TechNews alert, and it has been reported in many press articles and on many websites around the world.
More recent work by Boring et al (CHI 2010) has coined the term Touch Projection for this idea, as a user's touch on the mobile's screen is projected to another device's screen, wherever the particular interaction is occuring (see Touch projector website).
The key publication is number 2 below. Paper 1 describes a new markerless registration scheme, based on scale invariant features such as SURF and SIFT. Paper 3 is the original publication on the `display registration' idea.
