Touch UI can be broken down into the following three components:
Touch target—The area defined to accept touch input, which is not visible to the user
Touch element—The visual indicator of the touch target, which is visible to the user
Touch control—A touch target that is combined with a touch element that the user touches
The touch target can be larger than the touch element, but should never be smaller than it. The touch element should never be smaller than 60% of the touch target.
