Participant Comments● “It’s good to have the map on all the time,

but I want to know when to look at it.”

● “This kind of system may be useful in teaching people to use gestures when biking”

● Multiple participants noted that traffic noise reduced the effectiveness of button beeps as a feedback system.

● “You don’t have to do anything special, it comes naturally and it augments the reality.”

conclusion

● Projections augmenting vehicle headlights with information○ communicate with pedestrians○ showing driver’s intention○ computing & visualizing the field of safe travel

37

● Interface design of bicycles● Bike sharing e.g. Copenhagen bike● Display closer to normal line of sight

could improve safety
