Visual Distraction Effects between In-Vehicle Tasks with a Smartphone and a Motorcycle Helmet-Mounted Head-Up Display

Abstract

Besides motorists, also motorcyclists need safer user interfaces to interact with useful applications on the road. In this paper, distraction effects of in-vehicle tasks conducted with a head-up display (HUD) for motorcyclists were compared to smartphone tasks with 24 participants in a driving simulator. Compared to the smartphone tasks, the head-up display tasks decreased the percentage of inappropriately long glances by 45 percent. The head-up display tasks were also experienced as less demanding than the smartphone tasks. Additionally, the use of head-up display for navigation did not lead to gaze concentration effects compared to baseline driving. The head-up display is concluded to be a safer option for the tested tasks for motorcyclists than a smartphone. Based on earlier research, we assume that the use of peripheral vision allowed drivers to better maintain situational awareness during the head-up display tasks compared to the head-down smartphone tasks. In addition, the easy-to-learn haptic design of the head-up display handlebar controller could be used without vision.

Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction

“…For measuring the visual distraction potential of different in-car tasks, we used a method introduced by Kujala and Mäkelä (2015), which has been applied in studies by Grahn and Kujala (2018), Kujala et al (2016a) as well as in Kujala and Grahn (2017). The method contains two parts: visual distraction potential testing and driver sample validation.…”
