Abstract

本論文では,ネットワーク接続された多数の情報家電を一元的かつ直観的な操作により遠隔地からの制御を可能にする情報家電リモコンのフレームワークUbiREMOTEを提案する.UbiREMOTEは,ホームネットワークが敷設された空間の間取りとそこに設置された多数の情報家電を模した3D仮想空間を構築し,対象となる空間と情報家電の動作状況を3Dグラフィックスでリモコン端末に表示する機能,および,一般的な赤外線リモコンを用いて操作する手順に似せたインタフェースによる直観的に家電を操作するGUIを提供する.提案フレームワークを実現するため,処理能力の低い携帯端末上において軽快な動作を可能にする軽量3Dグラフィックス表示機構,仮想空間へ対象空間の情報を自動反映する機構を提案する.UbiREMOTEの有用性を確かめるため,本フレームワークに基づいたリモコンのプロトタイプをタブレットPCへ実装し,提案する3Dグラフィックス表示機構におけるフレームレートの測定およびユーザビリティについてのアンケート評価を行った.その結果,3Dグラフィックスの表示速度は提案する軽量3D描画機構を使わない場合と比べて約100倍向上し,ユーザビリティについてはテキストベースのものと比べ,家電の見つけやすさ,設置場所の認識のしやすさ,操作性,動作状況の確認のしやすさにおいてより優れていることを確認した.In this paper, we propose a framework named "UbiREMOTE" for controlling information appliances connected to a home network with a unified and intuitive user interface from a remote place. UbiREMOTE provides users with a way to control appliances in a home through a virtual space drawn on a mobile terminal screen which reflects the latest conditions of the real appliances and the rooms in the home. In addition, UbiREMOTE provides users with an intuitive and familiar way of controlling appliances by using a control window imitating the real remote controller for each appliance. To realize UbiREMOTE, we propose a lightweight 3D rendering mechanism that improves the drawing speed of 3D virtual space on mobile terminals and a mechanism that automatically reflects condition changes of the real space in the virtual space. We implemented a UbiREMOTE prototype on a tablet PC and conducted evaluation experiments. As a result, compared with the method that draws all objects, the rendering speed was improved about 100 times in the proposed method. Moreover, the usability of UbiREMOTE terminal outperformed the text-based terminal in finding the target appliance, recognizing its relative position in the space, and operating it.
