So true! At PlayStation Meeting 2011, when they were demonstrating the virtues of the LiveArea user interface on stage, and during it... anyone remembers the yellow-ish circle marks present when they showed certain actions, on the simulated screen? Well, when I first saw that I guessed it was a cursor that appeared when you touched the back (or the front), as an input guidance (a reference) for the user interface. I thought it was pretty cool as a way to navigate the menus without blocking the view on screen.I definitely agree with this. Would have been nice.
Later, on the translated version of the presentation, I saw that they explained specifically the marks were a representation of tactile inputs on the touch screen itself...
