Cycling is an environmentally friendly means of transport with growing popularity. However, there is still potential for increased road safety in the future. We argue that by making assistance systems available to cyclists, accidents could be prevented. In this paper, we focus on potential accidents caused by vehicle doors opening in a cyclist?s path of travel, which can lead to serious injuries to the cyclist. Using a mixed-methods approach, we explored how messages informing about a potentially opening door ahead are perceived and understood regarding usability and intuitiveness in a bicycle simulator study (N=24). We investigated how visual messages, visual messages and auditory icons, and visual and voice messages on a head-mounted device are subjectively perceived. We also assessed our participants? attitudes toward using such systems and mixed reality simulations for bicycle safety research in general. Our results show that participants preferred visual messages and auditory cues and found these types of notifications more enjoyable than visual messages alone. Furthermore, the results suggest that such a system would be used while cycling. Participants agreed that mixed reality simulation is suitable for testing/evaluating novel support systems and finding initial insights in the first step but confirmed that real-world testing on the road is mandatory nonetheless.
