“Tworlds”: Twirled Worlds for Multimodal ‘Padiddle’ Spinning & Tethered ‘Poi’ Whirling;
「トワールドズ」(回転する世界)：360度パノラマ環境に近い携帯と固定／ルームウエアー インタフェース 全体を使ったエンターテイメント

• Abstract: The Spatial Media Group at the University of Aizu is exploring on "mobile ambient" systems featuring individualized control of public display. Augmented virtuality scenes have been rigged to accept realtime data from distributed mobile devices. For instance, magnetometer data from tablets, phablets, and smartphones can modulate aspects of the scene, including virtual affordances, objects, and camera position. “Whole body” interfaces feature “poi”- and “padiddle”-style twirling. A unique feature of the augmented reality scenes is that the avatars are strategically ambidextrous and self-conscious, switching hands when the virtual camera moves around in a rotation & revolution phase-locked "inspection gesture," preserving intuitive alignment in both tethered and mirrored displayed projection modes.
• Description (E): Ambient media refers to a space's expressive channels, typically driven through fixed-location, public display equipment, such as computer screens, projection systems, stereo speakers, loudspeaker arrays, etc. Mobile media, in contrast, is portable but basically personal. "Mobile ambient" applications integrate these interaction styles, featuring cross-scale interactivity that exploits both personal mobile devices and location-based public displays. For particular instance, sensors on smartphones and tablets can measure orientation, which data can modulate ambient displays, including whirling of panoramic and turnoramic images and spatial sound, as well as avatar or rigged model attributes in augmented virtuality or mixed reality scenes.
  "Poi" is a performance art combining dance and juggling featuring a weight whirled at the end of a tether; “padiddling” is a playful activity featuring spinning objects such as plates or flying discs. Mobile ambient “smart-toy” groupware applications can support and amplify poi and padiddling recreations by leveraging modern multimedia and distributed roomware, mo-cap-style software for smart spaces and reactive rooms.
• Description (J): アンビエント メディアとは、空間を表現する方法です。コンピュータスクリーン、プロジェクター、ステレオスピーカー、複数のスピーカーなど固定されたものがあります。モバイルメディアは、対照的に小型で持ち運びが可能です。モバイルアンビエント アプリケーションは、これらを併せ持ったもので例えばスマートフォン上で動くリモートコントロールは無線でデレビを調節できます。
  個人レベルのモバイル装置や、固定された公共スクリーンなど、両方を開発する　“Smartoys”やゲームの開発。私達の最初の研究では、スマートフォンやタブレットのセンサーを使う事で，方向測定や周囲のディスプレイの調節ができます。それにより、空間音声、パノラマ画像、周囲の機器、アバターの調節ができ、拡張現実や複合現実を可能にさせます。
  「Poi」とは、アートとシャグリングとを持ち合わせたロープパフォーマンスです。「Padiddling」とは、皿やフライングディスクのように、回すオブジェクトの特色を持った活動を言います。モバイルアンビエントアプリケーションは，現代のマルチメディアを使ってポイやフライングディスクを回す事は，スマートスペースと反応する空間のルームウィアーを拡充し、サポートすることが出来ます。
