Do Traffic Warnings on Heads-Mounted Displays Improve Latent Hazard Anticipation? A Simulator Study
The present study examined the potential use of a head-mounted display (Google Glass) to enhance latent hazard anticipation in a variety of traffic conditions. Drivers aged 18 to 50, randomly allocated either to the Google Glass or control condition, all navigated seven different driving scenarios that presented latent hazards. Incoming traffic alerts were sent via a text message to the Google Glass display prior to the posted traffic sign displaying the same message. For example, the impending traffic stop sign was sent as the word ‘Stop Ahead’ to Google Glass. Drivers in the control group only viewed the posted traffic sign while the experimental Google Glass condition were provided both a traffic alert and the posted traffic sign. Participants received the incoming Google Glass text message prior to the hazard event. Participants’ eye-movements were recorded using an eye-tracker which collected point of gaze and fixation data. The results indicated that while the drivers in both groups showed no differences in their near latent hazard anticipation, the proportion of latent hazards anticipated earlier in the scenario (i.e., further upstream) by the drivers in the Google Glass group was 20 percentage points better than drivers in the control condition. Data showed that the warnings on the Google Glass did not distract drivers when compared to control group drivers. The ability to issue traffic alerts via the Google Glass (or any HMD) can help improve driving safety as measured by latent hazard anticipation.
