Touch Hit Testing

Purpose

The topics in this section provide an overview of support for Touch Hit Testing in Windows 8. Touch Hit Testing enables identifying an input target based on whether the content area of a UI element falls within the contact area or includes the contact point.

For Windows 8, touch hit testing uses complex contact geometry for the entire touch area rather than a single interpolated x-y coordinate. Using the entire contact geometry greatly improves precision and accuracy when you're identifying the most likely target of touch input.
