False Activation

An interaction error in gesture-based systems where the system incorrectly interprets a user's resting hand position or unintentional movement as a deliberate input command. In virtual reality, false activations are particularly problematic for users with motor impairments whose natural resting hand positions may closely resemble gesture poses—for example, a person with arthritis whose hand naturally rests in a near-closed position may constantly trigger grasp gestures. False activations increase frustration, reduce trust in the system, and force users to consciously maintain unnatural hand positions to avoid triggering unwanted interactions. Addressing false activations requires gesture recognition systems that can learn and accommodate individual users' resting positions and involuntary movements.
