The answers to the questions in Table 1 are summarized in Figure 3 (we grouped the related issues as much as possible). In the graph, negative answers are marked in shades of red while 'agreeing' answers are marked in shades of green. When based on the country, green represents Hungary, blue Romania and red Austria. As the number of respondents from the three countries were different, it would not make much sense to plot the number on the charts; instead, we provide percentages. The first few questions were about the \"internal\" data of the built-in navigation device. Figure 3a reveals that at least half of the devices in each country speak the national language. It is remarkable that almost all Austrian drivers use these devices with the German language, while a significant percentage of respondents in the other countries use \begin{table}

Table 1: The questions elaborated for this paper, and the number of respondents for each country. Figure 3: Answers about the sound effects I: (**a**) the output and (**b**) the input possibilities for voice navigation. a language different from their national language (whether the system knows the national language or not). Figure 3b shows the answers to two related questions that are also related to the use of sound in the interface. Whether the system can be controlled with voice instructions is shown here. Austria leads in this category. Lines indicate how many of the voice-controlled devices are used by the drivers. In Figure 4a, the input methods--touchscreen, navigation knob, or voice--are analyzed. The Romanian drivers are mostly touchscreen users. In Figure 3b, the question was whether the system could respond to voice commands--not whether it could only work with voice. The last question was about how the driver reacts to sound when the user accepts/selects something. Based on this, it can be said that the Austrians use this feature the least. After the sound-based questions, the questions were about the system's display. In Figure 5a, the most commonly used views can be seen. Any of the four following view options--Perspective, Top, North-oriented or Travel direction--can be selected.
