Playing Charades With Your Car –The Potential of Free-form and Contact-based Gestural Interfaces for Human Vehicle Interaction

摘要

Modern cars include a host of secondary in-vehicle technology that requires control by the driver.Center-stack touch-screen displays are a popular way to accommodate the proliferation of additionalfunctions through a flexible and scalable interface. However, touch-screens require visual attention formanual selection and provide poor tactile feedback to the driver, which can pose a significant riskwhile the vehicle is in motion. Inspired by a bimodal control approach, we propose the use of asteering wheel mounted thumb-based gestural interface as part of a larger multi-modal interactionstrategy for human vehicle interaction. Following the spirit of Guiard’s (1987) model of bimanualcontrol, a small set of simple gestures for the right hand select appropriate functions within the modeselected by the left hand. A pilot study shows promise of this approach over other, free-form gesturebasedmethods of interaction.
