Gesture recognition is a computational technique that maps patterns in sensor data to intentional human body movements — hand signs, head nods, full-body motions — using pattern-matching algorithms trained on annotated gesture corpora. Its parameters are: (1) a sensor modality that captures kinematic data (optical, depth, inertial, or multimodal), (2) a feature-extraction pipeline that reduces raw data to salient movement descriptors (joint angles, velocity profiles, spatial trajectories), (3) a classification model (template-matching, hidden Markov model, convolutional network, or transformer) that assigns labels to feature vectors, and (4) a threshold for confidence that determines whether a detected pattern qualifies as a recognized gesture. The persistence mechanism is the training dataset — a labeled corpus of gesture exemplars that defines the space of recognizable gestures for a given system. Without this dataset, the technique has no referents and cannot operate. [formal: gestus | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made computational technique for identifying intentional human movements from sensor data (camera images, depth sensors, inertial measurements). Built to persist through standardized algorithms, training datasets, and implementation protocols across consumer devices and industrial systems.

Gesture-recognition depends on feature extraction: the process must first extract distinguishing features from raw sensory data before it can recognize patterns. Remove feature extraction and gesture-recognition cannot operate — it has no features to recognize.
- cmref5f1v005og8vu7ubhlj26INSTANCE_OF →
gesture-recognition is a specific kind of technology — a human-made system for detecting and interpreting body movements. A competent speaker would call gesture recognition 'a technology' (e.g., 'gesture recognition technology'). The removal test does not apply to INSTANCE_OF.

Sensor fusion combines data from multiple sensors specifically to serve gesture-recognition systems with richer, more reliable input data. Per Law 8d: for whose sake? The fused sensor data (servant) points at gesture recognition (master) — recognition is the designed purpose.
