Numerous studies have provided vibrotactile warning patterns for vehicles, but efforts to faithfully incorporate users’ designs were difficult to find. This work adopts a participatory design using a vibration authoring tool to fully utilize user-defined design and determine representative patterns for various warning scenarios. We consider a driving seat with three vibrotactile actuators stimulating the driver’s back and two thighs. Haptics experts also craft two sets of vibrotactile warnings, which emphasize spatial consistency to warning event directions and prioritize congruence to commercial auditory warnings, respectively. The user-defined and two expert-designed sets are compared by a user study, which reveals the general drivers’ preference for simple and clear patterns. Specific pattern configurations and design implications across diverse warning scenarios can serve as practical guidelines for in-vehicle warning designers.

摘要

Numerous studies have provided vibrotactile warning patterns for vehicles, but efforts to faithfully incorporate users’ designs were difficult to find. This work adopts a participatory design using a vibration authoring tool to fully utilize user-defined design and determine representative patterns for various warning scenarios. We consider a driving seat with three vibrotactile actuators stimulating the driver’s back and two thighs. Haptics experts also craft two sets of vibrotactile warnings, which emphasize spatial consistency to warning event directions and prioritize congruence to commercial auditory warnings, respectively. The user-defined and two expert-designed sets are compared by a user study, which reveals the general drivers’ preference for simple and clear patterns. Specific pattern configurations and design implications across diverse warning scenarios can serve as practical guidelines for in-vehicle warning designers.
