One change I REALLY want is with the light glow. Why not have it extend around the perimeter of the touchpad? That way, it can serve as a better visual cue for things like health meter, visual indicator (grenade indicator flashes), etc.
As well, could the little pores in the touchpad be holes for light to shine through? That way, light can be used to divide the touchpad into its own little buttons! Developers could customize the light sources to manipulate into their own little inputs, dividing the touchpad into colour coded segments for touch-based buttons.
More generally, when playing in the dark, the controller would need to light up the touchpad, right? Unlike normal buttons, the touchpad requires more hand(finger?)-eye coordination. Playing in the dark and finding the touchpad becomes harder, unless the touchpad lights up, at least around the perimeter
The light source that stems from the back of the controller could probably shine through the touchpad. And on top of that, the controllers are already fitted with four lights, presumably more. It's the perfect substitute for half-assing a touchscreen/making the controller even pricier.
This could also be a good way to integrate some kind of keyboard onto the touchpad too. What do you guys think?
To me, the little pores on the controller seem to be perfect for light to shine through. What else could be under it lol. And why didn't they use the face button shapes for the pad found on the VITA? Why even have a texture at all, unless the holes act as some transparency for light?
Bah, just a guess
