FabriCar: Enriching the User Experience of In-Car Media Interactions with Ubiquitous Vehicle Interiors using E-textile Sensors

Abstract

This work explores e-textiles in the design space of Human-Vehicle Interaction (HVI) and compares distraction levels between e-textile and screen-based interactions during driving tasks. We developed three prototypes (in the steering wheel, headrest cover, and seat-belt pad) to support tactile interactions (tap, press, and swipe) with car interior elements for non-driving applications (such as media control). Our designs used digital embroidery to achieve aesthetic design qualities and wireless connection. In a deployment study with 16 participants, we collected quantitative and qualitative data through video recording, field observations, and user interviews. The study repeated all scenarios using screen-based interaction for comparison. Our findings present insights into fabric-based sensors including fewer collisions and a 302.7% decrease in eye distraction. These findings suggest new design opportunities, such as retrofitting existing vehicles, designing ideation toolkits for diverse users, devising an e-textile Fitts’ Law for reachability, and expanding vehicle interaction research within the HCI community.
