Gesture Language
The overall modality by which humans communicate with embodied AI systems through gestures, including hand signals, posture, and movement that the system detects and interprets. It names a communication channel rather than a single bounded event.
Operational Definition
Superordinate framework term; not operationalized as a per-interaction event. Specific measurable sub-constructs (for example, gesture-recognition accuracy or repair rate) would be operationalized individually.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Not directly measured as a single instrument; superordinate modality term. Component studies may report gesture-recognition accuracy or interpretation error rates, but the channel itself is not one measured construct.
