I have an aging parent who I want to acquaint with using an Android smartphone. Gestures are a bit of a problem for him, and I want to acquaint him with swipe-down, swipe right, long-press, single tap, double tap, pinch zoom. Preferably but not necessarily in the context of actual Android phone use – bringing down settings, moving a shortcut around on the desktop, moving a shortcut to another page on the desktop, etc.
