Multimodal and visual-only air gesture systems for navigating menus in the vehicle were developed and compared to a conventional direct touch system in a driving simulator using various distraction metrics. Participants using the multimodal air gesture system exhibited safer secondary task dwell patterns, but took longer to complete tasks and reported(More)
Bone conduction headphones are devices that transmit sound through the bones of a listener's head rather than through the air in their outer ear. They have been marketed as a safer way to enjoy audio content while walking, jogging, or cycling. However, listening to distracting sounds over bone conduction may still disrupt a listener's awareness of their(More)
Three novel interfaces for navigating a hierarchical menu while driving were experimentally evaluated. Prototypes utilized redundant visual and auditory feedback (multimodal), and were compared to a conventional direct touch interface. All three multimodal prototypes employed an external touchpad separate from the infotainment display in order to afford(More)
Drivers using SAE level 2-4 systems are required to supervise the vehicle, and may need to take control when certain conditions arise. While awareness of general automation certainty is crucial, the attention of the supervisory driver could also be directed toward specific areas or objects that the automated system is uncertain about. This video is a mockup(More)
The way a person chooses to utilize automated vehicle systems is not yet well understood. A structural equation model of acceptance of such systems of was constructed, applying theoretical models of automation acceptance to a real survey data set. The model indicated that perceptions of system utility may be more important than user characteristics,(More)
In-air gestures have become more prevalent in the vehicle cockpit in recent years. However, air gesture interfaces are still quite young and users have very little experience with such interactions. In the vehicle, ease of use relates directly to driver safety. Previous work has suggested that gesture sets created through participatory methods tend to be(More)
Three air gesture interfaces for browsing menus while driving were compared for menu selection tasks involving short or long menus. Driving performance, subjective workload, and menu task performance were measured. While performance was similar for short menus, for longer menus a repeated 'swipe' gesture did not perform as well as an 'angle scroll' gesture.(More)
Recent technological advances have led to the ability to reliably track the human body at low cost, allowing for the proliferation of Air Gesture (AG) interfaces. It has been proposed that AGs may be a safe and effective way to interact with in-vehicle technologies. However, designers do not presently have a well developed/adapted set of heuristics, which(More)
