Welcome to Android Central! Are you able to boot into Recovery Mode and wipe the cache partition? This won't erase any personal data. Reset: Samsung Galaxy Tab 3 | T-Mobile Support

If it still doesn't work, then the digitizer may have failed. You'd have to contact Samsung (if still under warranty) or bring it to a repair shop.
