Tsumiki Castle in LAVALVIRTUAL2013 http://youtu.be/EAAveGvxR0U The system gives players an experience that blocks stacked in the real world are dynamically transformed to a castle in a virtual world. The system enables players to create a realistic castle that reflects shape of blocks. Moreover, the system smoothly connects physical-world to virtual-world by means of a tangible interface and real-time computer graphics. The system was exhibited at "Ishikawa Dream Festival" for two days. We surveyed the evaluation of the system by questionnaires in the event, and found that the system was easy to play and gave enjoyment to everybody. We also exhibited this system in LAVAL VIRTUAL2013(FRANCE), and many people enjoyed TSUMIKI CASTLE. presented by Japan Advanced Institute of Science and Technology Miyata lab つみきキャッスルは、現実の世界でつみきをお城の形に積むと、それがバーチャルの世界でお城に変わる、そんな「新しいつみき遊び」です。 専用の筐体につみきを落として入れる事で、つみきを積み上げます。 積まれたつみき機の形状を各種センサで認識し、バーチャルの世界でお城に変換します。 発表・展示 学会発表：エンターテイメントコンピューティング学会２０１２ 展示：いしかわ夢未来博２０１２ , LAVAL VIRTUAL2013, NT金沢2013 企画：北陸先端科学技術大学院大学　宮田研究室 永井淳之介　沼野剛志　東孝文　Matthieu Tessier
