• Combining head-gaze for targeting with non-invasive tongue pressure for input significantly outperforms position-only tongue interfaces in ease of use, system response, and sense of control.
• Physiological input variability, typically suppressed in interface design, can be leveraged as a 'texture' for game feel by mapping residual effort signals to in-game tension or animacy.
• Tongue pressure input allows for hands-free interaction that avoids common XR issues like 'gorilla arm' fatigue and the 'Midas-touch' problem associated with gaze-only interfaces.
