Abstract
In-vehicle gestural interfaces are easy to use and increase safety by reducing visual demand on the driver. Prototype capacitive proximity sensing and depth-camera-based systems demonstrate that current technologies can recognize finger and hand gestures of varying complexity.
More than a decade, researchers have advocated the need for novel user interfaces that make it easier to control and monitor vehicular systems while driving.3 Research indicates that gestural interaction is a promising means to cover the full range of a driver’s operational needs while minimizing the cognitive and visual workload.Finger and hand gesture recognition systems suitable for in-car use can be broadly divided into (1) systems that require the user to attach colored markers or wear sen¬sors—for example, accelerometers, RFID tags, or data gloves;4 (2) touch-sensitive surfaces;2 and (3) infrastructure-less technologies such as depth cameras, thermal imaging, capacitive proximity sensing, and ultrasonic tracking
