ハンドトラッキングを用いたVRインタラクションでは，物理的フィードバックの欠如を補う視覚刺激が重要となる．本研究は，ハンドトラッキングによる選択操作において，3種類の視覚刺激（指先形状変化，ターゲット色変化，ターゲットの押し込み変化）を単一および複合提示し，ユーザーのパフォーマンスと主観評価への影響を調査した．ISO 9241-9準拠のマルチディレクションタッピングタスクとFittsの法則を用いて評価・分析した結果，色変化は移動時間を有意に短縮させ，押し込みはエラー率を減少させるが移動時間が増加するというトレードオフを示した．一方，指先形状変化は錯触覚，操作性，空間知覚の主観評価で高い評価を得た．本研究の知見は，VRアプリケーションの目的に応じた視覚刺激の設計指針を提供し，3D空間UIデザインの向上に寄与する． In hand-tracking-based VR interactions, visual stimuli are crucial to compensate for the lack of physical feedback. This research investigates how three types of visual stimuli―fingertip shape change, target color change, and target depression―affect user performance and subjective evaluation in selection tasks. These stimuli were presented both singularly and in combination. Evaluation and analysis, conducted using a multi-directional tapping task compliant with ISO 9241-9 and Fitts's law, revealed that the color change stimulus significantly shortened movement time. The target depression stimulus, however, demonstrated a trade-off, reducing the error rate but increasing movement time. Conversely, the fingertip shape change stimulus earned high subjective ratings for pseudo-haptic sensation, usability, and spatial perception. The findings from this study provide design guidelines for visual stimuli tailored to the objectives of VR applications and contribute to the enhancement of 3D spatial UI design.
