This article examines the "Full-Dive" concept (as seen in SAO) by defining its core requirements. It explains why conventional VR, which involves physical body movement, falls short of being a true Full-Dive. Furthermore, it details the five essential elements—Movement Suppression, Sensation Suppression, Motor Intention Acquisition, Simulation, and Sensory Feedback (Presentation)—and clarifies the positioning of Motion-Less VR within this framework.

Is Full-Dive Possible? | Artificial World Implementation Laboratory

Motion-Less VR（モーションレスVR）を中心に、運動の抑制・運動意図の取得・運動感覚提示を統合し、人工世界内で行為と感覚が完結するインターフェースの実現を目指します。

研究（Motion-Less VR）- 人工世界実装研究室

SAOのフルダイブを「成立条件」から整理する。現実で身体が動くVRがフルダイブと言いにくい理由を示し、運動の抑制・感覚の抑制・意図取得・シミュレーション・感覚提示の5要素とMotion-Less VRの位置づけを解説する。

## Core page: /fulldive
Topic: Can full-dive be realized?

Definition used on the page:
Full-dive is a state in which actions within an artificial world are established with bodily and sensory consistency.

Key distinction:
VR that relies on real-world body movement tends to make the basis of action and sensory consistency depend on the real world (i.e., “leak” outside the artificial world), so it should be treated as distinct from full-dive.

Five elements (treated equally; no priority):
1) Motion suppression
2) Sensation suppression
3) Motor-intention acquisition
4) Simulation
5) Sensory presentation (including kinesthetic sensation; e.g., kinesthetic illusion)

Positioning:
Motion-Less VR is an engineering approach that aims to satisfy these establishment conditions within an artificial world.

BCI note:
Brain-direct approaches (BCI) are often discussed, but for general use they face major constraints (sensor limitations, required resolution, robustness, safety, and operational cost). A reasonable inference is that if brain-direct full-dive becomes practical for general use, the conditions addressed by Motion-Less VR would already have been satisfied beforehand.

本研究室では，バーチャルリアリティとロボティクス技術を用いて人工世界を実装し，「現世界はコンピュータでシミュレートされた世界なのではないだろうか」という仮説の検証を試みます．
