gestikuid
Gestikuid is a term used in some discussions within biometrics and human–computer interaction to denote a stable gestural signature that can function as a unique identifier for an individual during interactive tasks. Etymologically, the word blends gestik (gestures) with uid (unique identifier). In this sense, gestikuid refers to a pattern of movements rather than a static biometric trait.
A gestikuid emerges from a conjunction of kinematic features: handshape sequences, trajectories, velocity profiles, timing, and
Measurement and analysis: gestikuid data are typically captured with cameras or inertial sensors, and analyzed using
Applications and status: in experimental settings, gestikuid could enable new forms of continuous authentication for smart
Limitations and concerns: high intra-person variability, changes in fatigue or health, cultural or individual differences in
