section_content: A Review of Empirical Work by Rouchitsas, A., and Alm, H. (2019). Front. Psychol. 10:2757. doi: 10. 3389/fpsyg. 2019. 02757 In the original article, there were five errors. 

1. The word "only" was used instead of "mainly. "

A correction has been made to section External Human-Machine Interfaces Evaluated Via Empirical Studies, sub-section Studies Employing Physical Prototypes. The corrected sentence reads as follows:

"While the aforementioned studies have used mainly subjective measures to assess interface effectiveness, Clamann et al. ( 2017 ) evaluated a communication interface by using an objective measure, namely decision time, alongside ratings and interviews. "

2. The word "reaction" was used instead of "decision". 

A correction has been made to External Human-Machine Interfaces Evaluated Via Empirical Studies, sub-section VR-Based Studies. The corrected sentence reads as follows:

"All designs proved to be efficient, as evidenced by shorter decision times when compared to the baseline condition (autonomous vehicle without interface). "

3. The word "experimental" was used instead of "behavioral". 

A correction has been made to Discussion section. The corrected sentence reads as follows: "Interestingly, the most convincing evidence were obtained largely from studies conducted in laboratory settings, namely monitor-based and VR-based studies, that utilized mainly objective measures, like reaction time, duration, and accuracy, in the context of behavioral tasks. "

Additionally, there was an error in The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
