Hi all,

What size of objects did you experiment with, what would be too small for an adult ?
For a child ??

Like touch and drag

    I try not to make any object that you have to tap smaller than 50x50. That's just me though. I want to see what I'm tapping! The blocks in Danger Cats are 52x52.

    Understand also that the resolution of the iPhone is greater than that of the desktop...
    I believe it's 160dpi as opposed to 72dpi?

    so that 50x50 looks like 32x32 or thereabouts...

    I like to try to keep things 'icon' sized if you have to interact with them.

    I have big fat hands, so things that completely disappear under my finger are annoying. But then again, I was probably the ONLY guy who was mad when they made the XBOX controller smaller. I loved the big one....

    I used 20x20 for the bombs in Detonate! and I am planning on resizing them a bit larger for the next version. I can always click and drag them in the iPhone, but I made the game and have more experience with it. I think first time users would have a problem.

    I use 50 x 50 & set the graphic to fixed. That way my graphic may only be 32 x 32, but it won't looked stretched & you still have plenty of button space.
