#4 recurrent measurements of user experience in avsauvsilink.org/avs2018/posters/victor...

• Less eyes on road with increased AD experience

• Perceived safety increased and then stabilized with increased AD experience

#4 Recurrent Measurements of User Experience in AVs

- A Method Development Experiment at AstaZero Proving Grounds

Results and conclusions

Future work AcknowledgementsFunded by SAFER Open Research at AstaZero, Knowledge Founda-tion, and Strategic Vehicle Research and Innovation (FFI).

The studies continue in real traffic within the project Trust in Intelligent Cars (TIC).

The experiment used quantitative and qualitative methods to investigate behavior over time when experiencing highly automated driving (AD).Research questions:• How does user behavior differ between two occasions?• What factors indicate a shift from first encounter behavior (tense) to more experienced use (calm)?

• Two occasions à 90 min for each test participant• Within subject design• Highly automated test vehicle (corr. SAE level 4)• 8 test participants (4 female, 4 male )• 80 km on rural road at Asta Zero proving grounds in Sweden

• Variations in driver behavior and first encounter effects were attenuated over time:• 1st occasion: exhilarated (”fun”, ”cool”, ”impressive”) • 2nd occasion: neutral state (”positive”, ”safe”, ”good”, “calm”)

• Several factors indicated the shift from tense to relaxed, e.g.: perceived safety, glance behavior, time to engage in non-driving tasks

• Faster to engage in non-driving tasks with increased AD experience
