Abstract

Online experiments offer several advantages compared to lab studies. We propose that reaction times in takeover requests in automated driving research can be evaluated using online experiments. Furthermore, we assume that online studies can complement simulator studies to some extent. However, online studies have several pitfalls (e.g. an uncontrolled environment). Affecting factors can occur in hardware, software, and human behavior. We provide a detailed methodology and technology section to reduce possible confounding factors and to increase the validity of automated driving online studies. Furthermore, to test the effect of the proposed methodology, we conducted a user study with a takeover scenario as online (n = 42) and simulator (n = 17) experiment. First results indicate that reaction times did not differ between the simulator and online experiment. Thus, we conclude that with some methodical refinements and practices, similar results can be achieved in online studies compared to simulator studies.

在线实验作为自动驾驶模拟器研究的补充:方法论见解

与实验室研究相比，在线实验有几个优势。我们提出可以使用在线实验来评估自动驾驶研究中接管请求的反应时间。此外，我们假设在线研究可以在一定程度上补充模拟器研究。然而，在线学习有几个陷阱(例如，一个不受控制的环境)。影响因素可能出现在硬件、软件和人类行为中。我们提供了详细的方法和技术部分，以减少可能的混淆因素，并提高自动驾驶在线研究的有效性。此外，为了测试所提出方法的效果，我们进行了一项用户研究，其中包括在线收购场景(n = 42)和模拟器(n = 17)实验。初步结果表明，模拟实验与在线实验的反应时间没有差异。因此，我们得出结论，通过一些系统的改进和实践，与模拟器研究相比，在线研究可以获得类似的结果。
