Abstract
本稿では、ユーザの方向感覚を保持するための全方位表示ウォークスルーシミュレータ(WTS)について述べる。本シミュレータでは、歩行者デッドレコニング(PDR)に用いられる小型無線センサモジュールによってユーザの足踏み(WIP)や向きの計測することで仮想環境内を移動する。これによりハンズフリーな操作が実現されるため、環境側の設計とハンドヘルドデバイスや手持ちの紙媒体資料の組み合わせの評価を行うことができる。さらにWTSユーザと指示者などの遠隔ユーザとの対面コミュニケーションを写実的アバタを通じて行うこともできる。
We present a walkthrough simulator (WTS) in which the display is omni-directional so as to preserve the viewer's sense of direction. A small-sized wireless sensor module for locomotion interface based on walking-in-place (WIP), detecting the viewer's step and orientation, is also presented to navigate the virtual constructions. The sensor module attached to the viewer's belt realizes the hands-free operation, which makes it possible to evaluate the usability of handheld devices or even just a paper map while walking around in virtual environments. In addition, the proposed WTS supports face-to-face communication between the simulator and a remote computer to help the subject reach their destination. The WTS is then applied to navigation in photorealistic environment for viewers to tour the remote indoor place without visiting in person, as an application of the proposed simulator. Based on the hands-free operation and omni-directional display, the proposed WTS can provide the viewers with a feeling that they experience the virtual environment as similar as possible with the real world.
