Innovations in the area of mobility often take years, sometimes decades, to become reality. Developing technologies over such long time spans is a risk, since it is unclear whether the public will accept the new technology, once available. This raises the question whether it is possible to evaluate the acceptance of a technology, which cannot yet be tested under real live conditions. Industry and researchers have come up with different solutions to this challenge, using descriptions, sometimes pictures and increasingly also videos and virtual reality demonstrations of the new technology.
So far it is not known whether these different methods of showcasing technology impact the factors that lead to acceptance or rejection of new technologies. In order to arrive at a more correct evaluation of the acceptance of a new technology, it is important to understand what effect the method of showcasing itself has on the user.
The study design included a laboratory experiment with three independent groups, whereby each of the groups was presented the concept of air taxis either via a picture, video, or virtual reality (VR). First, participants were given an informative introduction to air taxis, whereupon they were randomly assigned one of the three forms of media referring to a flight between the German cities Bonn and Cologne (solely Bonn for the VR group). Participants then rated items in regards to the level of immersion, the importance of sustainability, innovativeness, and the acceptance factors intention to use, performance expectancy, effort expectancy, hedonic motivation, social influence, reliability and trust as well as experience with videogames (for picture and video groups) and VR. Ratings referred to a 1-7 Likert scale (completely disagree to completely agree).
In sum, 191 students (VR: 65, video: 64, picture: 62) took part in the study via Unipark, whereas the mean age of participants was 22 years (SD=2.63) and the majority (64 %) were female. Most students had little to no knowledge about air taxis (87 %).
Selected Key Findings
- More than 75 % of respondents could imagine what it would be like to fly in an air taxi, while this perception was significantly more realistic for the VR group. Yet, the groups did not differ in their intention to use air taxis.
- Most participants (61 %) reported that they plan on using air taxis in the future while approximately 31 % could imagine implementing them at least on a regular basis.
- Overall, the acceptance factors effort expectancy, performance expectancy and social influence are significant predictors for the intention to use air taxis.
As indicated by previous research [e. g., 1, 2], this study showed that immersion, or sense of presence is higher in a VR setting than other forms of media. Interestingly, there was no difference between the picture and video group, which lets us draw implications for practice independent from air taxis. For instance, it appears that marketing efforts undertaken by companies do not necessarily have to be more successful if video content is included besides pictures. In addition, as shown by other studies [3, 4], social influence plays an important role when it comes to VR. Yet, these studies rather focus on the social influence related to interaction solely between subjects in the virtual space. Hence, one of the group‘s next studies will spotlight the impact of different forms of media and social influence on the intention to use air taxis.
