Controlling health care costs requires that limits be placed either on prices, quantities of services, or both. Prices are measurable and more easily controlled than is quantity and, consequently, health care cost containment has frequently focused on mechanisms for controlling prices. Regulatory approaches, however, may create market distortions and change access patterns. An alternative appro...

Studies on affordances typically focus on single objects. We investigated whether affordances are modulated by the context, defined by the relation between two objects and a hand. Participants were presented with pictures displaying two manipulable objects linked by a functional (knife-butter), a spatial (knife-coffee mug), or by no relation. They responded by pressing a key whether the objects...

Model-based approaches to 3D hand tracking have been shown to perform well in a wide range of scenarios. However, they require initialisation and cannot recover easily from tracking failures that occur due to fast hand motions. Data-driven approaches, on the other hand, can quickly deliver a solution, but the results often suffer from lower accuracy or missing anatomical validity compared to th...
