Interaction- and asymmetry-aware facial blendshape analysis for objective quantification of Parkinsonian hypomimia

Reduced facial expressivity (hypomimia) is an early motor feature of Parkinson’s disease (PD), yet its assessment still relies on subjective, coarse-grained clinical scales. Using ExpressionTracker, a consumer-grade application built on Apple’s ARKit framework, we derived 261 facial expression features during standardi...
