In-vehicle Performance and Distraction for Midair and Touch Directional Gestures

Rising diversity through novel forms of mobility and increasing connectivity through intelligent systems and wireless connection is leading to a complex traffic environment. However, traditional automotive interface research often focuses on the interaction between vehicle and driver, passenger, or pedestrian, not capturing the interconnected relationships among various traffic participants. Therefore, we developed a design space for Cross-Traffic Interaction (CTI) based on a focus group with six HCI experts, encompassing the dimensions: (1) interaction partners, (2) their traffic situations, and (3) their interaction relationship. Through a systematic literature review, we classified 116 publications, showing less-studied interaction possibilities. Illustrating the practical application of our design space, we developed three interactive prototypical applications: Shooting Stars, Flow Rider, and Road Reels. A study (N=12) shows that the applications were received well and could improve traffic experience. Overall, our design space serves as a foundational tool for understanding and exploring the challenges and diverse opportunities within CTI, bridging the gap between traditional automotive interface research and the complex realities of modern traffic environments.

Ultrasound-based mid-air haptic feedback has been demonstrated to be an effective way to receive in-vehicle information while reducing the driver's distraction. An important feature in communication between a driver and a car is receiving notifications (e.g., a warning alert). However, current configurations are not suitable for receiving notifications (haptic device on the center console requiring palmar feedback) as they force the driver to take their hands off-the-wheel and eyes off-the-road. In this paper, we propose “knuckles notifications,” a novel system that provides mid-air haptic notifications on the driver's dorsal hand while holding the steering wheel. We conducted a series of exploratory studies with engineers and UX designers to understand the perceptual space of the dorsal hand and design sensations associated with 4 in-car notifications (incoming call, incoming text message, navigation alert and driver assistant warning). We evaluated our system with driver participants and demonstrated that knuckles notifications were easily recognized (94% success rate) while not affecting the driving task, and mid-air sensations were not masked by background vibration simulating the car movement.
