Croix is the French word for “Cross”. The concept of analog cross navigation has been applied to the overall user experience – as in constant data transmission on a progressive continuum, as opposed to discrete transmission from one item to another; hence the name, Croix. Croix is the backbone of a series of finger touch-based mobile phones with full touch screens; it features an intuitive interface through on-screen touch input mapping which supports five different ways of interaction. An optimal distribution of the operational area and toolbox makes touch access much easier.
