Touch-screens can simplify navigation by far but the vast majority of phones on the market are not equipped with them. Cameras, on the other hand, are widespread even amongst low-end phones: in this paper we propose a vision-based pointing system that allows the user to control the pointer's position by just waving a hand, with no need for additional hardware.1 aGallo, O1 aArteaga, S1 aDavis, J  uhttp://users.soe.ucsc.edu/~orazio/demoICIP08.html
