Abstract:
Background: As Automated Driving Systems (ADS) technology gets assimilated into the
market, the driver’s obligation will be changed to a supervisory role. A key point to consider is the
driver’s engagement in the secondary task to maintain the driver/user in the control loop. The paper’s objective is to monitor driver engagement with a game and identify any impacts the task has
on hazard recognition. Methods: We designed a driving simulation using Unity3D and incorporated
three tasks: No-task, AR-Video, and AR-Game tasks. The driver engaged in an AR object interception game while monitoring the road for threatening road scenarios. Results: There were no
significant difference of means in the groups as per one-way ANOVA (F(2,33) = 4.34, p = .0213)
suggesting little to no impacts on the task involvement. Game scoring followed three profiles/phases: learning, saturation, and decline profile. From the profiles, it is possible to quantify/infer drivers’ engagement with the game task. Conclusion: The paper proposes alternative monitoring
that has utility, i.e., entertaining the user. Further experiments AR-Game focusing on real-world car
environment will be performed to confirm the performance following the recommendations derived from the current test.
