Beyond Accuracy: Auditing Allocative Harms in Facial-Gesture Recognition for People with Motor Impairments

Camera-based facial-gesture interfaces offer hands-free access for people with motor impairments (PwM), yet most recognition models are trained on able-bodied data and implicitly assume normative motor control and proprioception. We conducted a mixed-methods empirical study of 37 above-neck gestures performed by 11 Pw…
