Motor-Intuitive Interactions Based on Image Schemas: Aligning Touchless Interaction Primitives with Human Sensorimotor Abilities

Elicitation and evaluation studies investigated intuitiveness of touchless gestures but did not operationalize intuitiveness. For example, studies found that users fail to make accurate 3D strokes as interaction commands. But this phenomenon remains unexplained. In this paper, we first explain how making accurate 3D strokes is generally unintuitive, because it exceeds our sensorimotor knowledge. W...
