Touch　interaction　is　usually　implemented　on　a　computer　screen　or　a　projected　surface.　However,　tactile　quality　of　paper　is　attractive　and　intuitive　for　people　to　manipulate　in　traditional　paintings　and　storytelling.　In　order　to　enable　touch　interaction　on　paper,　we　present　MagicPAPER,　a　shadow-art　device　that　consists　of　a　pen,　kraft　paper,　a　projector,　a　gesture　sensing　device,　and　a　software　system.　With　the　purpose　of　illustrating　how　MagicPAPER　effectively　integrates　the　art-design　process　with　the　computer　and　communication　technology,　we　have　developed　eight　interactive　applications　simply　based　on　kraft　paper　and　mark　pen:　the　Dimension　Door,　Balls,　Palette,　Flat　Cube,　Piano,　Color　potion,　Fast　mask-　changing,　and　Candle.　Finally,　we　experimented　with　MagicPAPER　and　demonstrated　its　interactive　effects　by　detecting　the　gesture　of　a　finger　and　pen　on　kraft　paper　and　projecting　it　into　eight　interactive　applications.　Our　research　results　show　that　MagicPAPER　successfully　carries　out　paper-based　touch　interactions.　©　2018　Copyright　is　held　by　the　owner/author(s).
